- Fix null-pointer dereference introduced when snapshotting
was introduced. This occured because unlike the previous code,
vn_start_write() doesn't always return a non-NULL mp, as
filesystems may not support the VOP_GETWRITEMOUNT() call. For
now, rely on two pointers, so that vn_finished_write() works
properly.
- Fix locking problems on exit, introduced at some past time,
some when snapshots came in, where a vnode might not be
unlocked before being vrele'd in various error situations.

inode'' panic. This change corrects that problem by setting the
fs_active flag when the inode map changes to notify the snapshot
code that the cylinder group must be rescanned.

The binary format "bintime" is a 32.64 format, it will go to 64.64
when time_t does.
The bintime format is available to consumers of time in the kernel,
and is preferable where timeintervals needs to be accumulated.
This change simplifies much of the magic math inside the timecounters
and improves the frequency and time precision by a couple of bits.
I have not been able to measure a performance difference which was not
a tiny fraction of the standard deviation on the measurements.
this is a low-functionality change that changes the kernel to access the main
thread of a process via the linked list of threads rather than
assuming that it is embedded in the process. It IS still embeded there
but remove all teh code that assumes that in preparation for the next commit
which will actually move it out.

Make a slight change so that libkvm reaches the main thread via the
linked list, rather than assuming it is in the proc structure. Both
conditions are true in -current but only the first will be true in
the KSE M3 world.
Presumably the issue was with arparse.[ch]. Those are now in FREEBSD-Xlist
and FREEBSD-deletelist. So we do not import the Bison produced files that
was causing the problem.

o Fix timeout and justquit to have proper signatures for signal
handlers. Mark the args as __unused.
