Revert defective O_SEARCH implementation committed by manu@ along with
the *at system calls on November 18th of last year. Reasons to revert
it include:
   - it is incorrect in a whole variety of ways (but fortunately, one
     of them is that the missing and improper permission checks have
     no net effect);
   - it was committed without review or discussion;
   - core ruled that all the new O_* flags pertaining to the *at calls
     needed to wait until their semantics could be clarified.

manu was asked to revert it on these grounds but has ignored the request.

I have left O_SEARCH defined and visible and made open() explicitly
ignore it. This way, most code that tries to use it will continue to
build and run. I've also arranged lib/libc/c063/t_o_search.c so that
the tests that make use of the O_SEARCH semantics will disappear until
O_SEARCH comes back, and fixed some mistakes and/or incorrect hacks
that were causing some of these to succeed despite the broken O_SEARCH
implementation.

Disentangle do_sys_rename.

Elide the fs-wide rename lock for single-directory renames.  This

directories are before we lock the nodes.

what it does and doesn't do, and note some of what needs to change.

Change the syscall API for quotas over to the new non-proplib one.

   - struct vfs_quotactl_args -> struct quotactl_args
   - add sys/stdint.h to sys/quotactl.h for clean userland build
   - install sys/quotactl.h in /usr/include
   - update set lists for same
   - add new marshalling code in libquota
   - add new unmarshalling code in vfs_syscalls.c
   - discard proplib interpreter code in vfs_quotactl.c
   - add dispatching code for the 14 quotactl ops in vfs_quotactl.c
   - mark the proplib quotactl syscall obsolete
   - add a new syscall number for the new quotactl syscall
   - change the name of the syscall to __quotactl()
   - remove the decl of the old quotactl from quota/quotaprop.h
   - add a decl of the new quotactl to sys/quotactl.h
   - update the libc build
   - update ktruss
   - remove proplib marshalling code from libquota
   - update copy of syscall table in gdb ppc sources
   - hack rumphijack to accomodate new quotactl name (as I recall,
     pooka wanted such a name change to simplify something, but I
     don't really see what/how)

This change appears to require a kernel version bump for rumpish
reasons.

- collect the long (and sometimes incomplete) lists of basic flags into
  the header file and use that.
- sort the list of basic flags
- add MNT_RELATIME, ST_RELATIME
- mask all the op flags, for symmetry.

The real bit difference is (which is harmless):
    - mount was missing MNT_EXTATTR
    - update sets MNT_RDONLY twice
    - ops also could or in MNT_GETARGS, but this is impossible because the
      code would have chosen to do getargs then.

Everything new in headers is guarded #ifdef _INCOMPLETE_XOPEN_C063 since
some software (e.g.: xcvs in our own tree) will assume they can use openat(2)
when AT_FDCWD is defined. _INCOMPLETE_XOPEN_C063 will go away once support

Welcome to 5.99.53!  Merge rmind-uvmplock branch:

- Reorganize locking in UVM and provide extra serialisation for pmap(9).
  New lock order: [vmpage-owner-lock] -> pmap-lock.

- Simplify locking in some pmap(9) modules by removing P->V locking.

- Use lock object on vmobjlock (and thus vnode_t::v_interlock) to share
  the locks amongst UVM objects where necessary (tmpfs, layerfs, unionfs).

- Rewrite and optimise x86 TLB shootdown code, make it simpler and cleaner.
  Add TLBSTATS option for x86 to collect statistics about TLB shootdowns.

- Unify /dev/mem et al in MI code and provide required locking (removes
  kernel-lock on some ports).  Also, avoid cache-aliasing issues.

Thanks to Andrew Doran and Joerg Sonnenberger, as their initial patches
formed the core changes of this branch.

merge the bouyer-quota2 branch. This adds a new on-disk format
to store disk quota usage and limits, integrated with ffs
metadata. Usage is checked by fsck_ffs (no more quotacheck)

option QUOTA2 (added where QUOTA was enabled in kernel config files),
turned on with tunefs(8) on a per-filesystem
basis. mount_mfs(8) can also turn quotas on.

Remove the special refcount behavior (adding an extra reference to the
parent dir) associated with SAVESTART in relookup().

Check all call sites to make sure that SAVESTART wasn't set while
calling relookup(); if it was, adjust the refcount behavior. Remove
related references to SAVESTART.

The only code that was reaching the extra ref was msdosfs_rename,
where the refcount behavior was already fairly broken and/or gross;
repair it.

Add a dummy 4th argument to relookup to make sure code that hasn't
been inspected won't compile. (This will go away next time the
relookup semantics change, which they will.)

Abolish struct componentname's cn_pnbuf. Use the path buffer in the
pathbuf object passed to namei as work space instead. (For now a pnbuf
pointer appears in struct nameidata, to support certain unclean things
that haven't been fixed yet, but it will be going away in the future.)

This removes the need for the SAVENAME and HASBUF namei flags.

Introduce struct pathbuf. This is an abstraction to hold a pathname
and the metadata required to interpret it. Callers of namei must now
create a pathbuf and pass it to NDINIT (instead of a string and a
uio_seg), then destroy the pathbuf after the namei session is
complete.

Update all namei call sites accordingly. Add a pathbuf(9) man page and
update namei(9).

The pathbuf interface also now appears in a couple of related
additional places that were passing string/uio_seg pairs that were
later fed into NDINIT. Update other call sites accordingly.

Fix reference counting for vfsops in mount.  Otherwise it's possible
(for an unprivileged user) to force vfs modules to remain loaded
forever.  Also, it's possible for an admin with fat fingers to have
to curse out loud (a lot) and reboot.

.. or at least fix things as much as seems to be possible without
involving 1000 zorkmids.  do_sys_mount() takes either struct vfsops
(which hopefully came properly referenced) or a userspace string
for file system type.  The standard in-kernel calling convention
of "do_sys_mount(l, vfs_getopsbyname("nfs"), NULL," is not to be
considered healthy, kosher, or even tasty (although if vfs_getopsbyname()
fails the whole thing *currently* fails without the program counter
pointing to hyperspace).

Attention: Synchronization Oversight Committee!  In mount_domount(),
I postpone the call mutex_enter(&mp->mnt_updating) until right before
the VFS_MOUNT(9) call because (1) that looks to me like the earliest
possible opportunity for mp to become visible to any other LWP, because
it was just kmem_zalloc(9)'d and (2) it made extracting the common code
much easier.  Tell me if my reasoning is faulty.

PR kern/38141 lookup/vfs_busy acquire rwlock recursively

Simplify the mount locking. Remove all the crud to deal with recursion on
the mount lock, and crud to deal with unmount as another weirdo lock.

Hopefully this will once and for all fix the deadlocks with this. With this
commit there are two locks on each mount:

- krwlock_t mnt_unmounting. This is used to prevent unmount across critical
  sections like getnewvnode(). It's only ever read locked with rw_tryenter(),
  and is only ever write locked in dounmount(). A write hold can't be taken
  on this lock if the current LWP could hold a vnode lock.

- kmutex_t mnt_updating. This is taken by threads updating the mount, for
  example when going r/o -> r/w, and is only present to serialize updates.
  In order to take this lock, a read hold must first be taken on
  mnt_unmounting, and the two need to be held across the operation.

One effect of this change: previously if an unmount failed, we would make a
half hearted attempt to back out of it gracefully, but that was unlikely to
work in a lot of cases. Now while an unmount that will be aborted is in
progress, new file operations within the mount will fail instead of being
delayed. That is unlikely to be a problem though, because if the admin
requests unmount of a file system then s(he) has made a decision to deny
access to the resource.

kern/38135 vfs_busy/vfs_trybusy confusion

The symptom was that sometimes file systems would occasionally not appear
in output from 'df' or 'mount' if the system was busy. Resolution:

- Make mount locks work somewhat like vm_map locks.
- vfs_trybusy() now only fails if the mount is gone, or if someone is
  unmounting the file system. Simple contention on mnt_lock doesn't
  cause it to fail.
- vfs_busy() will wait even if the file system is being unmounted.

Network protocol interrupts can now block on locks, so merge the globals
proclist_mutex and proclist_lock into a single adaptive mutex (proc_lock).
Implications:

- Inspecting process state requires thread context, so signals can no longer
  be sent from a hardware interrupt handler. Signal activity must be
  deferred to a soft interrupt or kthread.

- As the proc state locking is simplified, it's now safe to take exit()
  and wait() out from under kernel_lock.

- The system spends less time at IPL_SCHED, and there is less lock activity.

  block devices. As a bonus remove the unreliable code that prevents
  multiple file system mounts on the same device. It's no longer needed.

Some Veriexec stuff that's been rotting in my tree for months.

Bug fixes:
  - Fix crash reported by Scott Ellis on current-users@.

  - Fix race conditions in enforcing the Veriexec rename and remove
    policies. These are NOT security issues.

  - Fix memory leak in rename handling when overwriting a monitored
    file.

  - Fix table deletion logic.

  - Don't prevent query requests if not in learning mode.


KPI updates:
  - fileassoc_table_run() now takes a cookie to pass to the callback.

  - veriexec_table_add() was removed, it is now done internally. As a
    result, there's no longer a need for VERIEXEC_TABLESIZE.

  - veriexec_report() was removed, it is now internal.

  - Perform sanity checks on the entry type, and enforce default type
    in veriexec_file_add() rather than in veriexecctl.

  - Add veriexec_flush(), used to delete all Veriexec tables, and
    veriexec_dump(), used to fill an array with all Veriexec entries.


New features:
  - Add a '-k' flag to veriexecctl, to keep the filenames in the kernel
    database. This allows Veriexec to produce slightly more accurate
    logs under certain circumstances. In the future, this can be either
    replaced by vnode->pathname translation, or combined with it.

  - Add a VERIEXEC_DUMP ioctl, to dump the entire Veriexec database.
    This can be used to recover a database if the file was lost.
    Example usage:

        # veriexecctl dump > /etc/signatures

    Note that only entries with the filename kept (that is, were loaded
    with the '-k' flag) will be dumped.

    Idea from Brett Lymn.

  - Add a VERIEXEC_FLUSH ioctl, to delete all Veriexec entries. Sample
    usage:

        # veriexecctl flush

  - Add a 'veriexec_flags' rc(8) variable, and make its default have
    the '-k' flag. On systems using the default signatures file
    (generaetd from running 'veriexecgen' with no arguments), this will
    use additional 32kb of kernel memory on average.

  - Add a '-e' flag to veriexecctl, to evaluate the fingerprint during
    load. This is done automatically for files marked as 'untrusted'.


Misc. stuff:
  - The code for veriexecctl was massively simplified as a result of
    eliminating the need for VERIEXEC_TABLESIZE, and now uses a single
    pass of the signatures file, making the loading somewhat faster.

  - Lots of minor fixes found using the (still under development)
    Veriexec regression testsuite.

  - Some of the messages Veriexec prints were improved.

  - Various documentation fixes.


All relevant man-pages were updated to reflect the above changes.

Binary compatibility with existing veriexecctl binaries is maintained.

Split the statvfs functions so that the 'work' is done to a kernel buffer
which can either be copied directly to userspace, or converted then copied.
Saves replicating a lot of code in the compat functions (esp. for
getvfsstat) at a cast of an extra function call in the non-emulated case -
which is unlikely to be measurable given the other costs of the actions
involved (even on vax).
Remove dofhstat() and dofhstatvfs() (and the last caller).
Remove some redundant stackgap_init() calls.

Change the way that emulations locate files within the emulation root to
  avoid having to allocate space in the 'stackgap'
  - which is very LWP unfriendly.
The additional code for non-emulation namei() is trivial, the reduction for
  the emulations is massive.
The vnode for a processes emulation root is saved in the cwdi structure
  during process exec.
If the emulation root the TRYEMULROOT flag are set, namei() will do an initial
  search for absolute pathnames in the emulation root, if that fails it will
  retry from the normal root.
".." at the emulation root will always go to the real root, even in the middle
  of paths and when expanding symlinks.
Absolute symlinks found using absolute paths in the emulation root will be
  relative to the emulation root (so /usr/lib/xxx.so -> /lib/xxx.so links
  inside the emulation root don't need changing).
If the root of the emulation would be returned (for an emulation lookup), then
  the real root is returned instead (matching the behaviour of emul_lookup,
  but being a cheap comparison here) so that programs that scan "../.."
  looking for the root dircetory don't loop forever.
The target for symbolic links is no longer mangled (it used to get the
  CHECK_ALT_xxx() treatment, so could get /emul/xxx prepended).
CHECK_ALT_xxx() are no more. Most of the change is deleting them, and adding
  TRYEMULROOT to the flags to NDINIT().
A lot of the emulation system call stubs could now be deleted.

Split the work for sys_stat, sys_lstat, sys_fstat and sys_fhstat out into
separate functions that don't do the copyout.
This allows all the compat_xxx versions to convert the 'struct stat' to
the correct format without using the 'stackgap'.
The stackgap isn't at all LWP friendly, and needs to be removed from
any compat functions that might involve threads (inc. clone()).
The code is still binary compatible with existing LKMs.

more fixes for the new vnode locking scheme:
 - don't use SAVESTART in calls to relookup() from unionfs,
   just vref() the desired vnode when we need to.
 - fix locking and refcounting in the unionfs EEXIST error cases.
 - release any vnode locks before calling VFS_ROOT(), vfs_busy() is enough.
   this allows us to simplify union_root() and fix PR 3006.
 - union_lock() doesn't handle shared lock requests correctly,
   so convert them to exclusive instead.  fixes PR 34775.
 - in relookup(), avoid reusing "dp" for different purposes,
   the error handling wasn't right.  (actually just get rid of dp.)
   also, change relookup() to ignore LOCKLEAF and always return the
   vnode locked since the callers already expect this.

a smorgasbord of improvements to vnode locking and path lookup:
 - LOCKPARENT is no longer relevant for lookup(), relookup() or VOP_LOOKUP().
   these now always return the parent vnode locked.  namei() works as before.
   lookup() and various other paths no longer acquire vnode locks in the
   wrong order via vrele().  fixes PR 32535.
   as a nice side effect, path lookup is also up to 25% faster.
 - the above allows us to get rid of PDIRUNLOCK.
 - also get rid of WANTPARENT (just use LOCKPARENT and unlock it).
 - remove an assumption in layer_node_find() that all file systems implement
   a recursive VOP_LOCK() (unionfs doesn't).
 - require that all file systems supply vfs_vptofh and vfs_fhtovp routines.
   fill in eopnotsupp() for file systems that don't support being exported
   and remove the checks for NULL.  (layerfs calls these without checking.)
 - in union_lookup1(), don't change refcounts in the ISDOTDOT case, just
   adjust which vnode is locked.  fixes PR 33374.
 - apply fixes for ufs_rename() from ufs_vnops.c rev. 1.61 to ext2fs_rename().

Massive restructuring and cleanup of Veriexec, mainly in preparation
for work on some future functionality.

  - Veriexec data-structures are no longer exposed.

  - Thanks to using proplib for data passing now, the interface
    changes further to accomodate that.

    Introduce four new functions. First, veriexec_file_add(), to add
    a new file to be monitored by Veriexec, to replace both
    veriexec_load() and veriexec_hashadd(). veriexec_table_add(), to
    replace veriexec_newtable(), will be used to optimize hash table
    size (during preload), and finally, veriexec_convert(), to convert
    an internal entry to one userland can read.

  - Introduce veriexec_unmountchk(), to enforce Veriexec unmount
    policy. This cleans up a bit of code in kern/vfs_syscalls.c.

  - Rename veriexec_tblfind() with veriexec_table_lookup(), and make
    it static. More functions that became static: veriexec_fp_cmp(),
    veriexec_fp_calc().

  - veriexec_verify() no longer returns the entry as well, but just
    sets a boolean indicating whether an entry was found or not.

  - veriexec_purge() now takes a struct vnode *.

  - veriexec_add_fp_name() was merged into veriexec_add_fp_ops(), that
    changed its name to veriexec_fpops_add(). veriexec_find_ops() was
    also renamed to veriexec_fpops_lookup().

    Also on the fp-ops front, the three function types used to initialize,
    update, and finalize a hash context were renamed to
    veriexec_fpop_init_t, veriexec_fpop_update_t, and veriexec_fpop_final_t
    respectively.

  - Introduce a new malloc(9) type, M_VERIEXEC, and use it instead of
    M_TEMP, so we can tell exactly how much memory is used by Veriexec.

  - And, most importantly, whitespace and indentation nits.

Built successfuly for amd64, i386, sparc, and sparc64. Tested on amd64.

accessed node was processed first and the earlierst last.

An extra benefit is the removal of the ugly hack from the Berkly days on
LFS.

In the proces, i've also replaced the various variations hand written loops
by the TAILQ_FOREACH() macro's.

First take at security model abstraction.

- Add a few scopes to the kernel: system, network, and machdep.

- Add a few more actions/sub-actions (requests), and start using them as
  opposed to the KAUTH_GENERIC_ISSUSER place-holders.

- Introduce a basic set of listeners that implement our "traditional"
  security model, called "bsd44". This is the default (and only) model we
  have at the moment.

- Update all relevant documentation.

- Add some code and docs to help folks who want to actually use this stuff:

  * There's a sample overlay model, sitting on-top of "bsd44", for
    fast experimenting with tweaking just a subset of an existing model.

    This is pretty cool because it's *really* straightforward to do stuff
    you had to use ugly hacks for until now...

  * And of course, documentation describing how to do the above for quick
    reference, including code samples.

All of these changes were tested for regressions using a Python-based
testsuite that will be (I hope) available soon via pkgsrc. Information
about the tests, and how to write new ones, can be found on:

	http://kauth.linbsd.org/kauthwiki

NOTE FOR DEVELOPERS: *PLEASE* don't add any code that does any of the
following:

  - Uses a KAUTH_GENERIC_ISSUSER kauth(9) request,
  - Checks 'securelevel' directly,
  - Checks a uid/gid directly.

(or if you feel you have to, contact me first)

This is still work in progress; It's far from being done, but now it'll
be a lot easier.

  because this feature is short-lived and there are no affected in-tree

okay, since there was no way to divide this to two commits, here it goes..

introduce fileassoc(9), a kernel interface for associating meta-data with
files using in-kernel memory. this is very similar to what we had in
veriexec till now, only abstracted so it can be used more easily by more
consumers.

this also prompted the redesign of the interface, making it work on vnodes
and mounts and not directly on devices and inodes. internally, we still
use file-id but that's gonna change soon... the interface will remain
consistent.

as a result, veriexec went under some heavy changes to conform to the new
interface. since we no longer use device numbers to identify file-systems,
the veriexec sysctl stuff changed too: kern.veriexec.count.dev_N is now
kern.veriexec.tableN.* where 'N' is NOT the device number but rather a
way to distinguish several mounts.

also worth noting is the plugging of unmount/delete operations
wrt/fileassoc and veriexec.

tons of input from yamt@, wrstuden@, martin@, and christos@.

Apply the NFS exports list rototill patch:

- Remove all NFS related stuff from file system specific code.
- Drop the vfs_checkexp hook and generalize it in the new nfs_check_export
  function, thus removing redundancy from all file systems.
- Move all NFS export-related stuff from kern/vfs_subr.c to the new
  file sys/nfs/nfs_export.c.  The former was becoming large and its code
  is always compiled, regardless of the build options.  Using the latter,
  the code is only compiled in when NFSSERVER is enabled.  While doing this,
  also make some functions in nfs_subs.c conditional to NFSSERVER.
- Add a new command in nfssvc(2), called NFSSVC_SETEXPORTSLIST, that takes a
  path and a set of export entries.  At the moment it can only clear the
  exports list or append entries, one by one, but it is done in a way that
  allows setting the whole set of entries atomically in the future (see the
  comment in mountd_set_exports_list or in doc/TODO).
- Change mountd(8) to use the nfssvc(2) system call instead of mount(2) so
  that it becomes file system agnostic.  In fact, all this whole thing was
  done to remove a 'XXX' block from this utility!
- Change the mount*, newfs and fsck* userland utilities to not deal with NFS
  exports initialization; done internally by the kernel when initializing
  the NFS support for each file system.
- Implement an interface for VFS (called VFS hooks) so that several kernel
  subsystems can run arbitrary code upon receipt of specific VFS events.
  At the moment, this only provides support for unmount and is used to
  destroy NFS exports lists from the file systems being unmounted, though it
  has room for extension.

Thanks go to yamt@, chs@, thorpej@, wrstuden@ and others for their comments
and advice in the development of this patch.

Implement expansion of special "magic" strings in symlinks into

This is enabled on a per-mount basis with the MNT_MAGICLINKS mount
flag.  It can be enabled at mountroot() time by building the kernel
with the ROOTFS_MAGICLINKS option.

The following magic strings are supported by the implementation:

	@machine	value of MACHINE for the system
	@machine_arch	value of MACHINE_ARCH for the system
	@hostname	the system host name, as set with sethostname()
	@domainname	the system domain name, as set with setdomainname()
	@kernel_ident	the kernel config file name
	@osrelease	the releaes number of the OS
	@ostype		the name of the OS (always "NetBSD" for NetBSD)

Example usage:

	mkdir /arch/i386/bin
	mkdir /arch/sparc/bin
	ln -s /arch/@machine_arch/bin /bin

More veriexec changes:

- Better organize strict level. Now we have 4 levels:
  - Level 0, learning mode: Warnings only about anything that might've
      resulted in 'access denied' or similar in a higher strict level.

  - Level 1, IDS mode:
    - Deny access on fingerprint mismatch.
    - Deny modification of veriexec tables.

  - Level 2, IPS mode:
    - All implications of strict level 1.
    - Deny write access to monitored files.
    - Prevent removal of monitored files.
    - Enforce access type - 'direct', 'indirect', or 'file'.

  - Level 3, lockdown mode:
    - All implications of strict level 2.
    - Prevent creation of new files.
    - Deny access to non-monitored files.

- Update sysctl(3) man-page with above. (date bumped too :)

- Remove FINGERPRINT_INDIRECT from possible fp_status values; it's no
  longer needed.

- Simplify veriexec_removechk() in light of new strict level policies.

- Eliminate use of 'securelevel'; veriexec now behaves according to
  its strict level only.

Rototill of the verified exec functionality.
  * We now use hash tables instead of a list to store the in kernel
    fingerprints.
  * Fingerprint methods handling has been made more flexible, it is now
    even simpler to add new methods.
  * the loader no longer passes in magic numbers representing the
    fingerprint method so veriexecctl is not longer kernel specific.
  * fingerprint methods can be tailored out using options in the kernel
    config file.
  * more fingerprint methods added - rmd160, sha256/384/512
  * veriexecctl can now report the fingerprint methods supported by the
    running kernel.
  * regularised the naming of some portions of veriexec.

Fix a partial construction problem that can cause race conditions
between creation of a file descriptor and close(2) when using kernel
assisted threads.  What we do is stick descriptors in the table, but
mark them as "larval".  This causes essentially everything to treat
it as a non-existent descriptor, except for fdalloc(), which sees a
filled slot so that it won't (incorrectly) allocate it again.  When
a descriptor is fully constructed, the code that has constructed it
marks it as "mature" (which actually clears the "larval" flag), and
things continue to work as normal.

While here, gather all the code that gets a descriptor from the table
into a fd_getfile() function, and call it, rather than having the
same (sometimes incorrect) code copied all over the place.

When unmounting a file system, acquire the syncer_lock before
vfs_busy'ing just before the dounmount() call.  This is to avoid
sleeping with the mountlist_slock held -- but we must acquire
syncer_lock before vfs_busy because the syncer itself uses
syncer_lock -> vfs_busy locking order.

Fix kern/7906: race between unmount and getnewvnode()

mp->mnt_flags & MNT_MWAIT is replaced by mp->mnt_wcnt, and a new mount
flag MNT_GONE is created (reusing the same bit).

In insmntque(), add DIAGNOSTIC check to fail if the filesystem vnode
is being moved to is in the process of being unmounted.

getnewvnode() now protects the list of vnodes active on mp with
vfs_busy()/vfs_unbusy().

To avoid generating spurious errors during a doomed unmount, change
the "wait for unmount to finish" protocol between dounmount() and
vfs_busy().  In vfs_busy(), instead of only sleeping once, sleep until
either MNT_UNMOUNT is clear or MNT_GONE is set; also, maintain a count
of waiters in mp->mnt_wcnt so that dounmount() knows when it's safe to
free mp.

tested by running a "while :; do mount /d1; umount -f /d1; done" loop
against multiple find(1) processes.

Per X/Open CAE Spec Issue 5 Version 2, change the buffer size argument of
readlink() from type `int' to type `size_t'.  This isn't an ABI change, since
the calling convention of our only LP64 platform (the Alpha) already promotes
this argument to a `long'.

This may not be the final action on this matter; readlink() still returns
an `int', which may change in a future revision of the standard.

Move the permission check in change_owner() back to ufs_vnops::ufs_chown()
again - the facility required in this context would be a filesystem-specific
super-user determination, which is not available yet.  Also, add some
clarification to a comment.

* Factor out some permission-checking code from ufs_setattr() into
  change_owner().
* Change the semantics of chown(), fchown() and lchown(): when requesting a
  change of the owner of a file, clear the set-user-id bit; analogous behaviour
  for group changes.
* Since the above is a violation of the semantics specified by POSIX and
  X/Open, add corresponding compatibility syscalls: __posix_chown(),
  __posix_fchown(), __posix_lchown().  (Neither fchown() nor lchown() is
  specified by POSIX; the prefix is intended to reflect the semantics.)
* Rename posix_rename() to __posix_rename() to follow the above convention.
