Introduce a bunch of new virsh commands for managing checkpoints in isolation. More commands are needed for performing incremental backups, but these commands were easy to implement by modeling heavily after virsh-snapshot.c. There is no need for checkpoint-revert or checkpoint-current since those snapshot APIs have no checkpoint counterpart. Similarly, it is not necessary to change which checkpoint is current when redefining from XML, since until we integrate checkpoints with snapshots, there is only a linear chain (and you can deduce the current checkpoint by instead using 'checkpoint-list --leaves'). Other aspects of checkpoint-list are also a bit simpler than the snapshot counterpart, in part because we don't have to cater to back-compat to older API. Upcoming patches will test these interfaces once the test driver supports checkpoints. Signed-off-by: Eric Blake <eblake@redhat.com> Reviewed-by: Daniel P. Berrangé <berrange@redhat.com>
