Eric Blake b736619f6e backup: Add list of checkpoints to domain
Wire up the use of a checkpoint list into each domain, similar to the
existing snapshot list.  This includes adding a function for checking
that a redefine operation fits in with the existing list, as well as
various filtering capabilities over the list contents.
