These patches are strongly based off Supriya Kannery's original bdrv_reopen() patches as part of the hostcache series, including the _prepare(), _commit(), and _abort() structure.
Some additions / changes: * Added support for multiple image reopen transactionally * Reopen changes are staged into temporary stashes in prepare(), and copied over in commit() (discarded in abort()). * Driver-level reopen file changes are mainly contained in the raw-* files.
