v2: Two passes inactivation. [Kevin] For now we only consider bs->file chain. In fact this is incomplete. For example, if qcow2 is a quorum child, we don't properly invalidate or inactivate it. This series recurses into the subtrees in both bdrv_invalidate_cache_all and bdrv_inactivate_all. This is also necessary to make the image locking cooperate with migration.
