qemu: checkpoint: Introduce support for deleting checkpoints accross snapshots

Allow deleting of checkpoints when snapshots were created along. The
code tracks and modifies the checkpoint list so that backups can still
be taken with such a backing chain. This unfortunately requires to
rename few bitmaps (by copying and deleting them) in some cases.
