interrupted while writing into the VHPT table. While here, make sure
memory accesses a properly ordered. Tag invalidation must happen
first so that the hardware VHPT walker will not be able to match
this entry while we're updating it and we have to make sure the new
new tag gets written only after the PTE is completely updated.

previously committed cleared pcb_current_pmap prior to changing
the region registers, but that was removed before committing.
Since we don't normally (at all?) pass a NULL pointer, the bug
was mostly harmless. Fix it while I'm here...
I'm here because we need to have data serialization after writing
to the region registers. Not doing so was likely the cause of the
hangs we were experiencing. General exceptions in cpu_switch may
also be caused by the lack of serialization.

switching user regions (region 0-4) with schedlock. Avoid unnecessary
recursion on schedlock by moving the core functionality to another
function (pmap_switch()) where we assert schedlock is held. Turn
pmap_install() into a wrapper that grabs schedlock. This minimizes
the number of callsites that need to be changed.
Since we already have schedlock in cpu_switch() and cpu_throw(),
have them call pmap_switch() directly. These were also the only two
calls to pmap_install() outside pmap.c, so make pmap_install() static
and remove its prototype from pmap.h

processes in the first pass. Among other things, this will give
us a chance to launder vnode-backed pages before concluding that
we need more swap. This is particularly useful for systems that
have no swap.
While here, update a comment and remove some long-unused code.

used in the EXTSRCDIR case, for example, if one finds it useful
to symlink /usr/src to an actual source tree, and use /usr/src
as the EXTSRCDIR.
This has no effects on release builds not using external directories.

Remove NO_CPU_CFLAGS and NO_CPU_COPTFLAGS. This should be safe since we
clear the environment and set __MAKE_CONF to /dev/null. NO_CPU_CFLAGS
actually breaks the Alpha release by preventing the inclusion of -mieee
in CFLAGS.
Do not set BUILDNAME as the release/Makefile already constructs a better
one than we do (though I wish there was a way to s/-SNAP/-TINDERBOX/)
