This series fixes the drive-mirror blockjob in case of "none" sync mode to always use the old (current) image file as the backing file of the newly created mirrored file (in case of "absolute-paths" mode).
It is rather important to get this into 1.7, as we will introduce an at least pretty strange API in case the original file is unbacked otherwise.
