pool_setlowat() may call pool_prime() and thus allocate memory

documentation should say pool_init, not pmap_init

Cross reference km_alloc(9) which is directly used rather than uvm_init(9).

replace links to uvm(9) to uvm_init(9); ok mpi

New flag PR_RWLOCK for pool_init(9) makes the pool use rwlocks instead
of mutexes. Use this immediately for the pool_cache futex pools.

the ioff argument to pool_init() is unused and has been for many
years, so this replaces it with an ipl argument. because the ipl
will be set on init we no longer need pool_setipl.

most of these changes have been done with coccinelle using the spatch
below. cocci sucks at formatting code though, so i fixed that by hand.

the manpage and subr_pool.c bits i did myself.

Remove some lies and document that passing the PR_WAITOK flag to pmap_init(9)
is the new way to request a non-interrupt-safe backend allocator.

a short note about PR_DEBUGCHK

document PR_NOWAIT.

(for those who've forgotten, if you can't sleep in pool_get, use
PR_NOWAIT, not zero. it makes the intention a lot clearer.
