Pull up following revision(s) (requested by bjh21 in ticket #1192):
	sys/sys/pool.h: revision 1.48
	sys/kern/subr_pool.c: revision 1.112
Medium-sized overhaul of POOL_SUBPAGE support so that:
1: I can understand it, and
2: It works.
Notable externally-visible changes are that POOL_SUBPAGE now has to be a
compile-time constant, and that trying to initialise a pool whose objects are
larger than POOL_SUBPAGE automatically generates a pool that doesn't use
subpages.
NetBSD/acorn26 now boots multi-user again.

Pull up revision 1.101 (requested by thorpej in ticket #474):
Fix some locking issues:
- Make the locking rules for pr_rmpage() sane, and don't modify fields
protected by the pool lock without actually holding it.
- Always defer freeing the pool page to the back-end allocator, to avoid
invoking the pool_allocator with the pool locked (which would violate
the pool_allocator -> pool locking order).
- Fix pool_reclaim() to not violate the pool_cache -> pool locking order
by using a trylock.
