Parts of vm_page_free_toq need the vm page queue lock held. To avoid a
LOR between the pmap lock and the vm page queue mutex in routines calling
vm_page_free, we either need to aquire the vm page queue lock in advance
(diminishing the value of the vm page lock) or we need to to defer page
freeing until the pmap lock is held. This commit takes the latter path with
the small but annoying down side that most of the internal routines now
need to pass around a page free list.
