Block layer patches:
- mirror: Fix early return from drain (could cause deadlocks)
- vmdk: Fixed probing for version 3 images
- vl: Fix to create migration object before block backends again (fixes
segfault for block drivers that set migration blockers)
- Several minor fixes, documentation and test case improvements
