Peter Lieven noticed that reqs->overlap_offset and reqs->overlap_bytes
are written outside bs->reqs_lock.  Patch 3 fixes it, while patches 1
and 2 are preparatory cleanups.

Paolo Bonzini (3):
  block: eliminate BDRV_REQ_NO_SERIALISING
  block/io: wait for serialising requests when a request becomes
    serialising
  block/io: take bs->reqs_lock in bdrv_mark_request_serialising
