Port the new PV entry allocator from amd64/i386. This allocator has two
advantages. First, PV entries are roughly half the size. Second, this
allocator doesn't access the paging queues, and thus it allows for the
removal of the page queues lock from this pmap.
Replace all uses of the page queues lock by a R/W lock that is private
to this pmap.
