[Qemu-devel] [PATCH v11 00/14] qemu-img: Implement commit like QMP |

qemu-img should use QMP commands whenever possible in order to ensure
feature completeness of both online and offline image operations. For
the "commit" command, this is relatively easy, so implement it first
(in the hope that indeed others will follow).
As qemu-img does not have access to QMP (due to QMP being intertwined
with basically everything in qemu), we cannot directly use QMP, but at
least use the functions the corresponding QMP commands are using (which
would be "block-commit", in this case).
v11:
- Rebased on Kevin's block branch
git-backport-diff output against v10:
Key:
[----] : patches are identical
[####] : number of functional differences between upstream/downstream patch
[down] : patch is downstream-only
The flags [FC] indicate (F)unctional and (C)ontextual differences, respectively
