Re: [PATCH 15/19] qemu: block: Add validator for bitmap chains accross backing chains

Add a validator which checks that a bitmap spanning multiple backing chain members doesn't look broken. The current rules are that no intermediate birmaps are missing (unfortunately it's hard to know whether the topmost or bottommost bitmap is missing) and none of the components is inconsistent. We can obviously improve it over time. The validator is also tested against the existing bitmap data we have for the backup merging test as well as some of the existing broken bitmap synthetic test cases.
