Switch pv entries over to a pool in preparation for making the i386 (more)
mpsafe. Most (all?) other architectures now use pools for this, including
non-direct pmap architetcures like sparc and sparc64. Use a special back-end
allocator for pool pages to solve bootstrapping problems. This back-end
allocator allocates the initial pages from kernel_map, switching to the
uvm_km_page allocator once the pmap has been fully initialized. The old
pv entry allocator allocated pages from kmem_map. Using the uvm_km_page
allocator avoids certain locking issues, but might change behaviour under
kva pressure. Time will tell if that's a good or a bad thing.
