We need to lock qcow2 mutex on accessing in-image metadata, especially
on updating this metadata. Let's implement it.

v2:

fix uninitialized variable in 03, found by Patchew

Vladimir Sementsov-Ogievskiy (3):
  block: move bdrv_can_store_new_dirty_bitmap to block/dirty-bitmap.c
  block/dirty-bitmap: return int from
    bdrv_remove_persistent_dirty_bitmap
  block/qcow2: proper locking on bitmap add/remove paths
