[Qemu-stable] [PATCH for-3.0 0/7] fix persistent bitmaps migration logic

[John Snow]

This is an updated version of Vladimir's proposal for fixing the
handling around migration and persistent dirty bitmaps.

Patches 1, 4, 6, and 7 update the testing for this feature.
Patch 2 touches up an error message.
Patch 3 removes dead code.
Patch 5 contains the real fix.

v2:
 - Add a new patch 4 as a prerequisite for what's now patch 5
 - Rework the fix to be (hopefully) cleaner, see patch 5 notes
 - Adjust error message in patch 2 (Eric)
 - Adjust test logic slightly (patches 6, 7) to deal with changes
   in patch 5.
