fix a simonb-timecounters regression.
...
the precision of getnanotime() is not suitable for file timestamps.
esp. when it's nfs-exported.
- introduce vfs_timestamp().
(the name is from freebsd. currently merely a wrapper of nanotime())
- for ufs-like filesystems, use it rather than getnanotime().
XXX check other filesystems.

The UID_MAX limit is not enforced by syscalls such as setreuid(2),
...
so I remove the assertion uid >= 0 && uid <= UID_MAX. This squashes
a bug where Quagga would panic my machine by passing a UID outside
the range [0, UID_MAX].
AFAICT, this restores the historical (pre-kauth) behavior.
It is likely that GIDs do not satisfy the assertion gid >= 0 &&
gid <= GID_MAX, so remove that, too.
Patch from elad.

Add one more buffer pool, for 512-byte buffers. On the one hand, most
...
systems will never, ever need this -- because they use 8k/1k or even,
these days, 16k/2k or 32k/4k filesystems. On the other hand, when you
do need this, you *really* need it: on anoncvs.netbsd.org, for instance,
where /tmp is 4k/512 and the filesystem contains tens or even hundreds
of thousands of single-frag directories, this essentially doubles the
efficiency of the allocator. Since the overhead of keeping one extra
pool around is minimal, just add it by default.

vfs_mountedon() can only and only handle special device nodes and will
...
otherwise generate an UVM trap or will access random memory. This is due to
the dereference of vp->v_specmountpoint that is really
vp->v_specinfo->si_mountpoint. The field v_specinfo is multiplexed with
other structs in the vun union in struct vnode like struct socket.
The patch adds a sanity check for accessing the specinfo fields by only
allowing VBLK nodes to be passed. In theory also VCHR could be valid since
its also a special node though mounting is only done on VBLK so be strict.
