vfio-user: implement VFIO_USER_DMA_MAP/UNMAP
When the vfio-user container gets mapping updates, share them with the
vfio-user by sending a message; this can include the region fd, allowing
the server to directly mmap() the region as needed.
For performance, we only wait for the message responses when we're doing
with a series of updates via the listener_commit() callback.
