Add bdrv_flush_all()
This patch adds a bdrv_flush_all() function. It's necessary to ensure that all
IO operations have been flushed to disk before completely a live migration.
N.B. we don't actually use this now. We really should flush the block drivers
using an live savevm callback to avoid unnecessary guest down time.
