CPUPhysMemoryClient: batch addresses in catchup
When a phys memory client registers and we play catchup by walking
the page tables, we can make a huge improvement in the number of
times the set_memory callback is called by batching contiguous
pages together. With a 4G guest, this reduces the number of callbacks
at registration from 1048866 to 296.
