Prepare for introducing a bunch of new public APIs related to

of rolling back to that state, while a checkpoint exists to
make it possible to create an incremental backup at a later
time.

All the error stuff should be in a separate commit. You don't even
mention it in the commit message.
Will split.

Ewwww. Don't mix includes with definitions.
Goes away in 6/9 when I create the public
<libvirt/libvirt-domain-checkpoint.h>. I should clearly document this in
the commit message and with a comment, if I can't find a way to reorder
the patches so that the hack isn't even needed.

I was thinking whether an UUID should not be used as well. But on the
other hand most management tools will stash an UUID into the name
anyways so it should be fine.
And, it matches that snapshots also use a name.
In fact, I'm half-heartedly thinking of refactoring into:
struct _virDomainAffiliate {
virObject parent;
char *name;
};
struct _virDomainSnapshot {
_virDomainAffiliate base;
};
struct _virDomainCheckpoint {
_virDomainAffliate base;
};
because there were several places where I could reuse more code between
snapshots and checkpoints if they had a common base type.

AFAIK we established that bumping these is pointless churn. The dates
can be re-establised from git history.
My emacs has a hook that does it automatically. I can turn the hook off
for libvirt, if you don't like the churn.
