add quota option

Revert vadvise(2) removal

This system call was used in legacy Lisp code, that was inherited to modern
age and still compiled against supported compat layers (e.g. in clisp,
oaklisp, Franz Lisp).

It used to instruct the kernel about paging policy (G/C aware, flush etc).

Newly compiled code (assuming that it will detect vadvise()) will use the
libc stub for vadvise(). The headers for this interface are gone.

vadvise(2) could be marked as COMPAT_80, but as long as we support ultrix,
sunos or aout68k ABI, don't bother with this.

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)
and is covered by the WAPBL journal. Enabled with kernel
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.

Kill fs_nfs.h and #ifdef NFS by making getfh() support unconditional
and nfssvc unsupport unconditional.  nfs server was just a fancy
NOP anyway for all except Ultrix.  I know I'm boring but I couldn't
imagine why someone would want to run an Ultrix nfs server (and I
also doubt that it would work anymore with all the changes to fs
exporting etc).

Remove lfs syscall support from compat.  I can't really imagine
anyone wanting to run lfs megamaid as a e.g. FreeBSD binary.
Besides, the real action has been in fcntl() for >5 years now.
The only place where the compat syscalls might have made the tiniest
bit of sense was netbsd32, but they were unimplemented there.

Convert the syscalls.master to a format from which it is easier
to parse and generate the compat name and basename (e.g. __stat50
and stat).  Use this to autogenerate __RENAME()'s to the rump_syscalls
header so that they can be called e.g. rump_sys_socket() instead
of rump_sys___socket30().

Update haad-dm branch to haad-dm-base2.

merge with head.

Make the emulations, exec formats, coredump, NFS, and the NFS server
into modules. By and large this commit:

- shuffles header files and ifdefs
- splits code out where necessary to be modular
- adds module glue for each of the components
- adds/replaces hooks for things that can be installed at runtime

Replace semid_t with intptr_t. No function change. This is a libc/kernel
private interface and so the name change should not affect any third
party code.

Per discussion with ad, remove most of the #include <sys/sa.h> lines
as they were including sa.h just for the type(s) needed for syscallargs.h.

Instead, create a new file, sys/satypes.h, which contains just the
types needed for syscallargs.h. Yes, there's only one now, but that
may change and it's probably more likely to change if it'd be difficult
to handle. :-)

Per discussion with matt at n dot o, add an include of satypes.h to
sigtypes.h. Upcall handlers are kinda signal handlers, and signalling
is the header file that's already included for syscallargs.h that
closest matches SA.

This shaves about 3000 lines off of the diff of the branch relative
to the base. That also represents about 18% of the total before this
checkin.

I think this reduction is very good thing.

Initial checkin of re-adding SA. Everything except kern_sa.c
compiles in GENERIC for i386. This is still a work-in-progress, but
this checkin covers most of the mechanical work (changing signalling
to be able to accomidate SA's process-wide signalling and re-adding
includes of sys/sa.h and savar.h). Subsequent changes will be much
more interesting.

Also, kern_sa.c has received partial cleanup. There's still more
to do, though.

Hi Perry!

Add FreeBSD sysctl emulation for their undocumented special OIDs rooted at
OID 0.  Only OID 0.3 is implemented for now, it 0.3 is the equivalent of
NetBSD's sysctlgetmibinfo().
This includes a new sysctl kern.osreldate with the value __NetBSD_Version__
for kernels with COMPAT_FREEBSD.

Both of these are used by 3ware's FreeBSD tw_cli, which seems to work now.

Fix the sync with head I botched.

FreeBSD emulation should not depend on NetBSD binary compatibility
options. Include compat_20_sys_*statfs* unconditionally.

Add opt_compat_netbsd.h because we need it for COMPAT_20; pointed out
by Jonathan Stone.

Replace the statfs() family of system calls with statvfs().
Retain binary compatibility.

uuidgen(2) syscall.  Originally from FreeBSD, ported by John Franklin in
PR#23470, with minor updates by me. This is only the syscall support
from that PR, for now.

Changes: port over fix from FreeBSD for multicast address generation.
Changed bcopy to memcpy.  For now, #ifdef notyet the portions of
kern_uuid.c that are meant to be used by (currently nonexistent) other
things in the kernel.  Added syscall to COMPAT_FREEBSD as well, though
that's currently not useful, as any program new enough to use this call
also uses other syscalls we don't (yet) emulate.

add the new syscalls to the list

Add a good enuf emulation of the MAP_STACK flag to the mmap()
syscall.  This allows programs which use MAP_STACK to work instead
of failing in weird and wonderous ways.

Changes to syscalls.master to exclude ntp_adjtime(2) entirely if NTP is not
defined.  Changes to other files will follow in a moment.

implement new signal syscalls in FreeBSD 4.0-RELEASE, using native syscalls:
sigaction, sigprocmask, sigsuspend, and sigpending.

Add names for many syscalls not yet implemented, including those in
FreeBSD 4.0-RELEASE.  Also implement the following using existing NetBSD
syscalls:  pread, pwrite, getsid, mlockall, munlockall, __getcwd.

We have now native issetugid.

pull up rev 1.16 from trunk (tv)

Substantial signal handling changes:
* Increase the size of sigset_t to accomodate 128 signals -- adding new
  versions of sys_setprocmask(), sys_sigaction(), sys_sigpending() and
  sys_sigsuspend() to handle the changed arguments.
* Abstract the guts of sys_sigaltstack(), sys_setprocmask(), sys_sigaction(),
  sys_sigpending() and sys_sigsuspend() into separate functions, and call them
  from all the emulations rather than hard-coding everything.  (Avoids uses
  the stackgap crap for these system calls.)
* Add a new flag (p_checksig) to indicate that a process may have signals
  pending and userret() needs to do the full (slow) check.
* Eliminate SAS_ALTSTACK; it's exactly the inverse of SS_DISABLE.
* Correct emulation bugs with restoring SS_ONSTACK.
* Make the signal mask in the sigcontext always use the emulated mask format.
* Store signals internally in sigaction structures, rather than maintaining a
  bunch of little sigsets for each SA_* bit.
* Keep track of where we put the signal trampoline, rather than figuring it out
  in *_sendsig().
* Issue a warning when a non-emulated sigaction bit is observed.
* Add missing emulated signals, and a native SIGPWR (currently not used).
* Implement the `not reset when caught' semantics for relevant signals.

Note: Only code touched by the i386 port has been modified.  Other ports and
emulations need to be updated.

NFSCLIENT -> NFS

Snapshot of work-in-progress, committed to private branch.

These changes implement machine-independent root device and file system
selection.  Notable features:

	- All ports behave in a consistent manner regarding root
	  device selection.
	- No more "options GENERIC"; all kernels have the ability
	  to boot with RB_ASKNAME to select root device and file system
	  type.
	- Root file system type can be wildcarded; a machine-independent
	  function will try all possible file systems for the selected
	  root device until one succeeds.
	- If the root file system fails to mount, the operator will
	  be given the chance to select a new root device and file
	  system type, rather than having the machine simply panic.
	- nfs_mountroot() no longer panics if any part of the NFS
	  mount process fails; it now returns an error, giving the
	  operator a chance to recover.
	- New, more consistent, config(8) grammar.  The constructs:

		config netbsd swap generic
		config netbsd root on nfs

	  have been replaced with:

		config netbsd root on ? type ?
		config netbsd root on ? type nfs

	  Additionally, the operator may select or wildcard root file
	  system type in the kernel configuration file:

		config netbsd root on cd0a type cd9660

	  config(8) now requires that a "root" specification be
	  made.  "root" may be wired down or wildcarded.  "swap" and
	  "dump" specifications are optional, and follow previous
	  semantics.

	- config(8) has a new "file-system" keyword, used to configure
	  file systems into the kernel.  Eventually, this will be used
	  to generate the default vfssw[].

	- "options NFSCLIENT" is obsolete, and is replaced by
	  "file-system NFS".  "options NFSSERVER" still exists, since
	  NFS server support is independent of the NFS file system
	  client.

	- sys/arch/<foo>/<foo>/swapgeneric.c is no longer used, and
	  will be removed; all information is now generated by config(8).

As of this commit, all ports except arm32 have been updated to use
the new setroot().  Only SPARC, i386, and Alpha ports have been
tested at this time.  Port masters should test these changes on their
ports, and report any problems back to me.

More changes are on their way, including RB_ASKNAME support in
nfs_mountroot() (to prompt for server address and path) and, potentially,
the ability to select rarp/bootparam or bootp in nfs_mountroot().
