This adds implicit rollback support during A/B style updates. If you explicitly start a checkpoint with -1, needsRollback will trigger if the update fails, and should be used if any additional cleanup is needed that is not covered by A/B itself. Test: All Checkpoint tests pass Bug: 111020314 Change-Id: I88b4a1098c6bac4dc1438a54c8a8f59577a6c17b
