block: Manage backing file references in bdrv_set_backing_hd()
This simplifies the code somewhat, especially when dropping whole backing file subchains. The exception is the mirroring code that does adventurous things with bdrv_swap() and in order to keep it working, I had to duplicate most of bdrv_set_backing_hd() locally. We'll get rid again of this ugliness shortly.
