Re: [PATCH 3/3] remote_driver: Implement virStreamInData() callback

When using the monolithic daemon the driver for virStream is always virFDStreamDrv and thus calling virStreamInData() results in calling virFDStreamInData(). But things are different with split daemon, especially when a client connects to one of hypervisor daemons (e.g. virtqemud) and then lets the daemon connect to the storage daemon for vol-upload/vol-download. Here, the hypervisor daemon acts like both client and server. This is reflected by stream->driver pointing to remoteStreamDrv, which doesn't have streamInData callback implemented and thus vol-upload/vol-download with sparse flag fails.
