By the end of your series, I still don't see any use of

either of these functions in block/nbd-client.c.  I think that's a good
thing (we refactored it so that nbd/client.c is doing ALL the reading
from the wire, and block/nbd-client.c is relying on nbd/client.c to do
the work), but it means this part of the patch is no longer necessary,
unless I'm missing something.
