libvhost-user: Speedup gpa_to_mem_region() and vu_gpa_to_va()
Let's speed up GPA to memory region / virtual address lookup. Store the
memory regions ordered by guest physical addresses, and use binary
search for address translation, as well as when adding/removing memory
regions.
Most importantly, this will speed up GPA->VA address translation when we
have many memslots.
