This switches the checkpoint calls that don't need to return a value to return 0 on success, and an error on failure. This will be transalted to exceptions for java binder users. needsCheckpoint and needsRollback still return a boolean value. Test: vdc setCheckpoint 2 then reboot 3 times checking state Bug: 112901762 Change-Id: Idd3b5e6036631562a86d5123f533b86cf3bd6032
