To allow for fault injection of the virCommand dry run, add the ability to register a callback. The callback will be passed the argv, env and stdin buffer and is expected to return the exit status and optionally fill stdout and stderr buffers.

virCommandProcessIO should be skipped on a dry run, since it overwrites the buffers. Jan
