[PATCH v2 0/6] qemu-img: Add convert --bitmaps

[Eric Blake]

Without this series, the process for copying one qcow2 image to
another including all of its bitmaps involves running qemu and doing
the copying by hand with a series of QMP commands.  This makes the
process a bit more convenient.

Series can also be downloaded at:
https://repo.or.cz/qemu/ericb.git/shortlog/refs/tags/qemu-img-bitmaps-v2

Since v1:
- patches 1, 3 are new
- patch 2 (old 1/3) moves more operations into new file
- patch 4 no longer a separate thread (was at v2 in isolation)
- patches 4, 6 rebased to take advantage of 3
- patch 5, 6 (old 2-3/3) have other minor tweaks
