Stuff UFS_ in front of a few of ufs's symbols to reduce namespace
pollution. Specifically:
   ROOTINO -> UFS_ROOTINO
   WINO -> UFS_WINO
   NXADDR -> UFS_NXADDR
   NDADDR -> UFS_NDADDR
   NIADDR -> UFS_NIADDR
   MAXSYMLINKLEN -> UFS_MAXSYMLINKLEN
   MAXSYMLINKLEN_UFS[12] -> UFS[12]_MAXSYMLINKLEN (for consistency)

Sort out ext2fs's misuse of NDADDR and NIADDR; fortunately, these have
the same values in ext2fs and ffs.

No functional change intended.

change vflushbuf() to take the full FSYNC_* flags.
translate FSYNC_LAZY into PGO_LAZY for VOP_PUTPAGES() so that
genfs_do_io() can set the appropriate io priority for the I/O.
this is the first part of addressing PR 46325.

Implement extended attribute listing for UFS1.

Modify lsextattr(8) so that it does not expect each attribute name to be
prefixed by its length. This enable extattr_list_(file|link|fd) to
return a buffer matching its documentation. This also makes the interface
similar to what Linux and FUSE do, which is nice for interoperability.

Note that since we had no EA implementation supporting listing, we do
not break anything.

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.

Cleanup ffs fsync and make devices on wapbl enabled file systems work here:

- Replace the ugly sync loop in ffs_full_fsync() and ffs_vfs_fsync() with
  vflushbuf().  This loop is a relic of softdeps and not needed anymore.

- Add ffs_spec_fsync() for device nodes on ffs file systems that calls
  spec_fsync() like all other file systems do and then updates the ctime.

Discussed on tech-kern.

fsync:

- atime updates were not being synced.

ffs_sync:

- In some cases the sync vnode was acting like now dead /usr/sbin/update.
  It was examining vnodes that it should have ignored.

- It would find dirty inodes and try to flush them. Often ffs_fsync()
  cheerfully ignored the flush request due to the fsync bug. Such inodes
  remained dirty and were repeatedly re-examined by the syncer until
  vnode reclaim or system shutdown.

- We were marking our place in the per-mount vnode list even though in
  most cases there was not flush to perform. While not a bug, this wasted
  CPU cycles because a TAILQ_NEXT would have sufficed.

PR kern/40525 panic: ffs_valloc: dup alloc

- A fix for an issue that can lead to "ffs_valloc: dup" due to dirty cg
  buffers being invalidated. Problem discovered and patch by dholland@.

- If the syncer fails to lazily sync a vnode due to lock contention,
  retry 1 second later instead of 30 seconds later.

- Flush inode atime updates every ~10 seconds (this makes most sense with
  logging). Presently they didn't hit the disk for read-only files or
  devices until the file system was unmounted. It would be better to trickle
  the updates out but that would require more extensive changes.

- Fix issues with file system corruption, busy looping and other nasty
  problems when logging and non-logging file systems are intermixed,
  with one being the root file system.

- For logging, do not flush metadata on an inode-at-a-time basis if the sync
  has been requested by ioflush. Previously, we could try hundreds of log
  sync operations a second due to inode update activity, causing the syncer
  to fall behind and metadata updates to be serialized across the entire
  file system. Instead, burst out metadata and log flushes at a minimum
  interval of every 10 seconds on an active file system (happens more often
  if the log becomes full). Note this does not change the operation of
  fsync() etc.

- With the flush issue fixed, re-enable concurrent metadata updates in
  vfs_wapbl.c.

The new API is enabled on a kernel option NEWVNGATE.  This option is
not enabled by default in any kernel config.

Presented and discussed on tech-kern with much input from
Bill Studenmund <wrstuden@netbsd.org> and YAMAMOTO Takashi <yamt@netbsd.org>.

Experimental support for extended attributes on UFS1 file systems, using a
backing file per attribute type indexed by inode number to hold the extended
attributes.

This is working pretty well on my test systems, except for the "autostart"
feature.  I need someone with a better handle on the VFS locking protocol
to go over that.

This is a work-in-progress.  There are parts of this that could be re-factored
allowing this approach to be used on other types of file systems.

Add code to UBCify LFS.  This is still behind "#ifdef LFS_UBC" for now
(there are still some details to work out) but expect that to go
away soon.  To support these basic changes (creation of lfs_putpages,
lfs_gop_write, mods to lfs_balloc) several other changes were made, to
wit:

* Create a writer daemon kernel thread whose purpose is to handle page
  writes for the pagedaemon, but which also takes over some of the
  functions of lfs_check().  This thread is started the first time an
  LFS is mounted.

* Add a "flags" parameter to GOP_SIZE.  Current values are
  GOP_SIZE_READ, meaning that the call should return the size of the
  in-core version of the file, and GOP_SIZE_WRITE, meaning that it
  should return the on-disk size.  One of GOP_SIZE_READ or
  GOP_SIZE_WRITE must be specified.

* Instead of using malloc(...M_WAITOK) for everything, reserve enough
  resources to get by and use malloc(...M_NOWAIT), using the reserves if
  necessary.  Use the pool subsystem for structures small enough that
  this is feasible.  This also obsoletes LFS_THROTTLE.

And a few that are not strictly necessary:

* Moves the LFS inode extensions off onto a separately allocated
  structure; getting closer to LFS as an LKM.  "Welcome to 1.6O."

* Unified GOP_ALLOC between FFS and LFS.

* Update LFS copyright headers to correct values.

* Actually cast to unsigned in lfs_shellsort, like the comment says.

* Keep track of which segments were empty before the previous
  checkpoint; any segments that pass two checkpoints both dirty and
  empty can be summarily cleaned.  Do this.  Right now lfs_segclean
  still works, but this should be turned into an effectless
  compatibility syscall.

The softdep code sometimes use vfs_vget .. vput. For removals, these
would result in a vop_inactive call for the vnode each time, resulting
in vinvalbuf->fsync. The original softdep code avoided the fsync
in vinvalbuf by not calling it if there were no dirty blocks. This
was changed in NetBSD. Also, flush_inodedeps was changed to mark
the inode as modified so that it would do an inode update and flush the
last one. This combination basically caused a sync write for each removed
file in an rm -rf (showing up delayed from the syncer a lot of the time).

If called from vinvalbuf (FSYNC_RECLAIM), and there were no dirty blocks
or pages to begin with, still do everything as normal, so that possible dirty
blocks in transit to disk are properly waited for, etc, but don't pass
UPDATE_WAIT to VOP_UPDATE, since there is no need for it in that case.

a whole bunch of changes to improve performance and robustness under load:

 - remove special treatment of pager_map mappings in pmaps.  this is
   required now, since I've removed the globals that expose the address range.
   pager_map now uses pmap_kenter_pa() instead of pmap_enter(), so there's
   no longer any need to special-case it.
 - eliminate struct uvm_vnode by moving its fields into struct vnode.
 - rewrite the pageout path.  the pager is now responsible for handling the
   high-level requests instead of only getting control after a bunch of work
   has already been done on its behalf.  this will allow us to UBCify LFS,
   which needs tighter control over its pages than other filesystems do.
   writing a page to disk no longer requires making it read-only, which
   allows us to write wired pages without causing all kinds of havoc.
 - use a new PG_PAGEOUT flag to indicate that a page should be freed
   on behalf of the pagedaemon when it's unlocked.  this flag is very similar
   to PG_RELEASED, but unlike PG_RELEASED, PG_PAGEOUT can be cleared if the
   pageout fails due to eg. an indirect-block buffer being locked.
   this allows us to remove the "version" field from struct vm_page,
   and together with shrinking "loan_count" from 32 bits to 16,
   struct vm_page is now 4 bytes smaller.
 - no longer use PG_RELEASED for swap-backed pages.  if the page is busy
   because it's being paged out, we can't release the swap slot to be
   reallocated until that write is complete, but unlike with vnodes we
   don't keep a count of in-progress writes so there's no good way to
   know when the write is done.  instead, when we need to free a busy
   swap-backed page, just sleep until we can get it busy ourselves.
 - implement a fast-path for extending writes which allows us to avoid
   zeroing new pages.  this substantially reduces cpu usage.
 - encapsulate the data used by the genfs code in a struct genfs_node,
   which must be the first element of the filesystem-specific vnode data
   for filesystems which use genfs_{get,put}pages().
 - eliminate many of the UVM pagerops, since they aren't needed anymore
   now that the pager "put" operation is a higher-level operation.
 - enhance the genfs code to allow NFS to use the genfs_{get,put}pages
   instead of a modified copy.
 - clean up struct vnode by removing all the fields that used to be used by
   the vfs_cluster.c code (which we don't use anymore with UBC).
 - remove kmem_object and mb_object since they were useless.
   instead of allocating pages to these objects, we now just allocate
   pages with no object.  such pages are mapped in the kernel until they
   are freed, so we can use the mapping to find the page to free it.
   this allows us to remove splvm() protection in several places.

The sum of all these changes improves write throughput on my
decstation 5000/200 to within 1% of the rate of NetBSD 1.5
and reduces the elapsed time for "make release" of a NetBSD 1.5
source tree on my 128MB pc to 10% less than a 1.5 kernel took.

Never call softdep_sync_metadata() in the FSYNC_RECLAIM case.  Any pending
blocks are detached from the vnode at this point.  When the dependencies are
broken to enable writing the blocks, the vnode will be regenerated.  (The only
reason we sync buffers in this case is that they have to be detached from the
vnode.)

Change the sementics of the last parameter from a boolean ("waitfor") to
a set of flags ("flags").  Two flags are defined, UPDATE_WAIT and
UPDATE_DIROP.

Under the old semantics, VOP_UPDATE would block if waitfor were set,
under the assumption that directory operations should be done
synchronously.  At least LFS and FFS+softdep do not make this
assumption; FFS+softdep got around the problem by enclosing all relevant
calls to VOP_UPDATE in a "if(!DOINGSOFTDEP(vp))", while LFS simply
ignored waitfor, one of the reasons why NFS-serving an LFS filesystem
did not work properly.

Under the new semantics, the UPDATE_DIROP flag is a hint to the
fs-specific update routine that the call comes from a dirop routine, and
should be wait for, or not, accordingly.

Closes PR#8996.

Move vinvalbuf's check for dirty blocks into ffs_fsync, to ensure that
mode and ownership bits are flushed to disk before the vnode is
reclaimed.

The check, introduced in the softdep merge, assumes that if no blocks
are dirty, no file data *or metadata* needs to be flushed to disk.  This
is true of ffs, but is not true of lfs, and may not be true of other
filesystems.
