[libvirt] [PATCH v3 20/31] remote_driver: Implement virStreamSendHole
Now that we have RPC wrappers over VIR_NET_STREAM_HOLE we can
start wiring them up. This commit wires up situation when a
client wants to send a hole to daemon.
To keep stream offsets synchronous, upon successful call on the
daemon skip the same hole in local part of the stream.
