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.

Fam Zheng (3):
  block: Invalidate all children
  block: Drop superfluous invalidating bs->file from drivers
  block: Inactivate all children
