[libvirt] [PATCH] Let remoteClientStream only do RX if requested.

[Chris Lalancette]

Right now, the stream stuff assumes that a stream is always
going to be used for transmit.  This is not the case, and in
fact doesn't work with the tunnelled migration stuff.  Add
a flag to remoteClientStream() to allow it to do RX only.
