in nd6_cache_lladdr(), set nd6_gctimer to ln_expire just after the state

Ok, I'm breaking my promise. I promised to not do anything with the
old vm system and I hoped that it would make people help me to switch all
archs to uvm. But that didn't help.

Fix pool to work with the old vm system (not optimal, ha!).
permit [] hostname formats in CVSroot, for v6
Add printing of pool statistics for -m.
From NetBSD.
Change the ffs inode allocation from using malloc to pool.
Saves approx. 256k memory on a GENERIC i386 and moves 670k out of kmem_map.
Sigh. PR_WAITOK, not M_WAITOK
Document FLAVOR_EXT, FULLPKGNAME, new COMMENT meaning
Use pool for allocating vnodes.
Even though vnodes are never freed (could be) this gives us big memory and
kmem_map savings.
Introduce powerup/powerdown actions, when power status changes (AC
connected/disconnected).
Get pmap->cpus_using before the pmap structure is touched. Besides, we
need to do this before playing with pmap_expand().
Solves a few more pmap data corruption problems.
Fix thinko in kn_do_query error checking; angelos OK'd
use err/warn, space police
Paranoid -- clear tdbi field in mbuf pkthdr.
Reformat comment.
new timeouts
strlcpy instead of strncpy + \0
contify usbdevs a little
Sync style, typo, and comments a little closer to NetBSD.  art@ ok
