alc ef5ae2f2e5 Rename pmap_collect() to pmap_pv_reclaim() and rewrite it such that it no
longer uses the active and inactive paging queues.  Instead, the pmap now
maintains an LRU-ordered list of pv entry pages, and pmap_pv_reclaim() uses
this list to select pv entries for reclamation.

Note: The old pmap_collect() tried to avoid reclaiming mappings for pages
that have either a hold_count or a busy field that is non-zero.  However,
this isn't necessary for correctness, and the locking in pmap_collect() was
insufficient to guarantee that such mappings weren't reclaimed.  The new
pmap_pv_reclaim() doesn't even try.
