[libvirt] [PATCH v6 0/9] Incremental backups, focus on API

I'm fairly confident that these API are ready to go (that is, I've got
qemu code in the wings to implement these API for the qemu driver, as
demonstrated at last KVM forum, and it shouldn't be too hard to add
support in the test driver to get some 'make check' coverage similar
to what I recently added for snapshots). I'm hoping the APIs make it
in for 5.2, even if I'm still dealing with review churn on the later
parts of my v5 series (there has been a lot of rebasing from earlier
review comments, so v5 is currently still the most recent version that
I was able to run demos with, although I hope to post the rest of v6
soon).
The biggest diffs compared to v4/v5 are addressing many of John
Ferlan's grammar suggestions, removing some TODO items from the public
API (although implementing those changes, such as the new
VIR_DOMAIN_SNAPSHOT_CREATE_QUIESCE, is still on my todo list),
splitting some large patches (checkpoints and backups are now
separated), moving the backup APIs into libvirt-domain.c instead of
piggybacking on libvirt-domain-checkpoint.c, and adding 2 more API
(virDomainSnapshotCreateXML2 to create a checkpoint at the same time
as a snapshot; virDomainListJobIds to learn the job ids of all
currently running backup jobs [the initial implementation will only
ever have job id 1 due to qemu 4.0 limitations, but the API was
designed with future expansion in mind]). I've also got some
preliminary patches to snapshot in this posting based on things
noticed while working checkpoints.
