Add a new --sparse switch that does nothing more than enables the sparse streams feature for this command. Among with the switch new helper function is introduced: virshStreamSkip(). This is the callback that is called whenever daemon sends us a hole. In the callback we reflect the hole in underlying file by seeking as many bytes as told.
