Aside from my comments made on particular patches, this patch series
is fine.
I do think we should split up the libnbd get_init_flags into two
separate calls though, and that changes some of the nbdkit tests a
little.

The NBD protocol is adding an extension to let servers advertise
initialization state to the client: whether the image contains holes,
and whether it is known to read as all zeroes. With recent enough
libnbd, the nbd plugin can pass this information through.
