Re: [PATCH 23/32] qemu: backup: Rewrite backup bitmap handling to the new bitmap semantics

Reuse qemuBlockGetBitmapMergeActions which allows to remove the ad-hoc

iplementatio of bitmap merging for backup. The new approach is simpler

and also more robust in case some of the bitmaps break as they remove the dependancy on the whole chain of bitmaps working.

The new approach also allows backups if a snapshot is created outside of libvirt. Additionally the code is greatly simplified.
