This implements handling of bitmaps during block-commit so that
incremental backups are not broken after commit.
Note that this applies on top of
https://www.redhat.com/archives/libvir-list/2020-February/msg01125.html
or can be fetched at
git fetch https://gitlab.com/pipo.sk/libvirt.git reopen-impl
https://gitlab.com/pipo.sk/libvirt/-/commits/reopen-impl
It uses blockdev-reopen so it's required to use that series. As noted
the branch mentioned above the series contains patches to enable
incremental backup and blockdev-reopen and depends on the following qemu
patches:
https://lists.gnu.org/archive/html/qemu-block/2020-02/msg01423.html
https://lists.gnu.org/archive/html/qemu-block/2020-02/msg01467.html

Is it guaranteed that the new member 'disabledBitmapsBase' is properly
initialised? How about something along the lines of

Even if explicit initialisation is somehow not needed here, I'd consider that
fact worth a line of explanation in the commit message.
g_new0 and VIR_ALLOC (which uses calloc) always zero-out the memory
which is allocated. This means that setting integers to 0, pointers to
NULL and booleans to false is always assumed when allocating a new
object and we rarely re-initialize it explicitly if ever.

qemuBlockBitmapsHandleCommitStart prepares for disabling the bitmaps in
the 'base' of the commit job so that the bitmaps are not dirtied by the
commit job. This needs to be done prior to start of the commit job.
qemuBlockBitmapsHandleCommitFinish then calculates the necessary merges

New subject: [PATCH 10/13] qemuDomainBlockCommit: Handle bitmaps on start of commit
On start of the commit job, we need to disable any active bitmap in the
base. Use qemuBlockBitmapsHandleCommitStart to calculate which and call
the appropriate QMP APIs. We use blockdev-reopen to make the 'base'
writable to disable the bitmaps.

New subject: [PATCH 11/13] qemuDomainBlockPivot: Handle merging of bitmaps when pivoting an active block-commit
Active layer block commit makes the 'base' image the new top image of
the disk after it finishes. This means that all bitmap operations need
to be handled prior to this happening as we'd lose writes otherwise.
The ideal place is to handle it when pivoting to the new image as only
guest-writes would be happening after this point.
Use qemuBlockBitmapsHandleCommitFinish to calculate the merging
transaction.
