Include a prerequisite header (so this is consistent again with the
NFSv2 state).

Second batch of cleanup changes.
This time mostly making a lot of things static and some unused
variables here and there.

Eliminate sloppy common-style declarations. There should be none left for
the LINT configuation.

Changes to support version 3 of the NFS protocol.
The version 2 support has been tested (client+server) against FreeBSD-2.0,
IRIX 5.3 and FreeBSD-current (using a loopback mount). The version 2 support
is stable AFAIK.
The version 3 support has been tested with a loopback mount and minimally
against an IRIX 5.3 server. It needs more testing and may have problems.
I have patched amd to support the new variable length filehandles although
it will still only use version 2 of the protocol.

Before booting a kernel with these changes, nfs clients will need to at least
build and install /usr/sbin/mount_nfs. Servers will need to build and
install /usr/sbin/mountd.

NFS diskless support is untested.

Forward-declare a few structures to avoid warning messages.

Implement fs.nfs MIB variables.

This is a bunch of changes from NetBSD. There are a couple of bug-fixes.
But mostly it is changes to use the list-maintenance macros instead of
doing the pointer-gymnastics by hand.

Prototyping and general gcc-shutting up. Gcc has one warning now which looks
bad, I will get to it eventually, unless somebody beats me to it.

More idempotency....... this is fun :-)

Made NFS attribute cache timeouts kernel config file tunable via
NFS_MINATTRTIMO and NFS_MAXATTRTIMO.

Fix a race that can occur when nfs nfsiod threads are being created.
Without this patch it was possible for a different thread that calls
nfs_asyncio() to snitch a newly created nfsiod thread that was
intended for another caller of nfs_asyncio(), because the nfs_iod_mtx
mutex was unlocked while the new nfsiod thread was created. This patch
labels the newly created nfsiod, so that it is not taken by another
caller of nfs_asyncio(). This is believed to fix the problem reported
on the freebsd-stable email list under the subject:
FreeBSD NFS client/Linux NFS server issue.

Remove the thread argument from the FSD (File-System Dependent) parts of
the VFS. Now all the VFS_* functions and relating parts don't want the
context as long as it always refers to curthread.

In some points, in particular when dealing with VOPs and functions living
in the same namespace (eg. vflush) which still need to be converted,
pass curthread explicitly in order to retain the old behaviour.
Such loose ends will be fixed ASAP.

While here fix a bug: now, UFS_EXTATTR can be compiled alone without the
UFS_EXTATTR_AUTOSTART option.

VFS KPI is heavilly changed by this commit so thirdy parts modules needs
to be recompiled. Bump __FreeBSD_version in order to signal such
situation.

Change the default timeout for caching attributes of a directory in the NFS
client from 30 seconds to 3 seconds. After the recent changes to add
caching of negative name cache lookups, a negative name cache hit will
persist until the client notices the parent directory has changed. The
higher the attribute cache timeout on directories, the longer that can take,
so lower the default timeout for directories to match that of regular files.

Expand the per-node access cache to cache permissions for multiple users.
The number of entries in the cache defaults to 8 but is easily changed in
nfsclient/nfs.h. When the cache is filled, the oldest cache entry is
evicted when space is needed.

I mirrored the changes to the NFSv[23] client in the NFSv4 client to fix
compile breakage. However, the NFSv4 client doesn't actually use the
access cache currently.
