The 'basic' case is just a single backing store layer containing the
bitmaps so we just copy the bitmaps over to the backup bitmap.

Upcoming patches are going to rewrite and semantically modify how
bitmaps are handled during blockjobs. This is possible as incremental
backup is not yet fully enabled.
As the changes are going to be incompatible with any current test data
remove all test cases for bitmap handling during checkpoint deletion,
incremental backups, block commit, block copy, and bitmap validation
operations.
The tests will be gradually added back later after the code and
test-data is refactored.

Add test code which will crawl a fake internal list of checkpoints and
generate the list of bitmaps for merging to gather the final bitmap for
the backup.
The initial tests cover the basic case of all bitmaps being present in
the top layer of the backing chain.
