This patchset enables the in-memory part of the incremental backup
feature, without transactional support.

Support for transactions was separated into a separate series which
is also now available on-list. Getting this portion of the series
committed will help stabilize work on bitmap persistence and bitmap

Thanks to Fam Zheng for the original versions of this patchset,
And thanks to Max for reviewing 2,395 versions of it since.


04: Some in-line documentation for block_dirty_bitmap_lookup
     Changed behavior with respect to aio_context
       (always acquire, release if pbs == null, give to user otherwise)
10: Removed vestigial (currently nop) bdrv_enable_dirty_bitmap call
     Kept R-B.
16: Added some comments to test_check_boundary_bits.
     Kept R-B.
17: Folded in refactor from "incremental transactions v1" (Poor Kitty)
18: Pulled forward from "incremental transactions v1"
     Kept R-B from that series.
19: Folded in refactor from "incremental transactions v1"
     Added offset assertions into wait_incremental
20: Removed error tolerance from wait_until_completed, as
     these patches no longer make use of that feature.

Thanks for squashing the iotest refactoring code into 17, 19, and 20!


It wound up being easier than I thought it would be at first, and it keeps the second series smaller, so we can focus on how badly I named everything.
