block/backup: add backup_is_cluster_allocated
Modify bdrv_is_unallocated_range to utilize the pnum return from
bdrv_is_allocated, and in the process change the semantics from
"is unallocated" to "is allocated."
Optionally returns a full number of clusters that share the same
allocation status.
This will be used to carefully toggle bits in the bitmap for sync=top
initialization in the following commits.
