kernel: Remove numerous #include <sys/thread2.h>.

Most of them were added when we converted spl*() calls to
crit_enter()/crit_exit(), almost 14 years ago. We can now
remove a good chunk of them again for where crit_*() are
no longer used.

I had to adjust some files that were relying on thread2.h
or headers that it includes coming in via other headers
that it was removed from.

kernel - Implement QUICKHALT shortcut for unmounting during shutdown

* Add the MNTK_QUICKHALT flag which allows the system to just unlink but
otherwise ignore certain mount types during a halt or reboot. For now
we flag tmpfs, devfs, and procfs.

* The main impetus for this is to reduce the messing around we
do with devfs during a shutdown. Devfs has its fingers, and its
vnodes, prettymuch sunk throughout the system (e.g. /dev/null, system
console, vty's, root mount, and so on and so forth). There's no
real need to attempt to unwind all of that mess nicely.

Initial import of binutils 2.22 on the new vendor branch

Future versions of binutils will also reside on this branch rather
than continuing to create new binutils branches for each new version.

NFS - Fix unmounting blockages, fix tick interval, hack cpu assignments.

* Umount was having problems due to the way the helper threads were
being shutdown. Should be fixed.

* The NFS timer, which is responsible for handling retransmits and
timeouts, did not need to be set to one tick (10ms). 200ms is
just fine.

* Hack cpu assignments for the tx and rx helper threads.

NFS - Remove old nfsiod, start adding new kernel thread infrastructure

* Remove all the nfsiod junk.

* Add two per-mount threads, one for reading from the socket, one for writing
to the socket, in a new file nfs_iod.c

* Implement a quick and dirty synchronous, single threaded nfs_doio()
loop in the writer thread to test basic mechanics.

Remove the thread argument from all mount->vfs_* function vectors,
replacing it with a ucred pointer when applicable. This cleans up a
considerable amount of VFS function code that previously delved into
the process structure to get the cred, though some code remains.

Get rid of the compatibility thread argument for hpfs and nwfs. Our
lockmgr calls are now mostly compatible with NetBSD (which doesn't use a
thread argument either).

Get rid of some complex junk in fdesc_statfs() that nobody uses.

Remove the thread argument from dounmount() as well as various other
filesystem specific procedures (quota calls primarily) which no longer
need it due to the lockmgr, VOP, and VFS cleanups. These cleanups also
have the effect of making the VFS code slightly less dependant on the
calling thread's context.
