Allow lockmgr to work without a current process. Disallowing that
was a mistake in the lockmgr rewrite.

Added includes of smp.h for SMP.
This eliminates a bazillion warnings about implicit s_lock & friends.

Fix kern_lock so that it will work. Additionally, clean-up some of the
VM systems usage of the kernel lock (lockmgr) code. This is a first
pass implementation, and is expected to evolve as needed.

for the lock manager code has not changed, but the underlying implementation
has changed significantly. This change should not materially affect
our current SMP or UP code without non-standard parameters being used.
