This patch moves bdrv_attach_child() from the individual places that add a backing file to a BDS to bdrv_set_backing_hd(), which is called by all of them. It also adds bdrv_detach_child() there. For normal operation (starting with one backing file chain and not changing it until the topmost image is closed) and live snapshots, this constitutes no change in behaviour. For all other cases, this is a fix for the bug that the old backing file was still referenced as a child, and the new one wasn't referenced.
