Hi all!

We need to copy bitmaps to new top node on external snapshot, to
not break incremental backup chain.

The only thing to do is to allow block-dirty-bitmap-merge to work
with different nodes, here it is.

  qapi: support external bitmaps in block-dirty-bitmap-merge
  iotests: test external snapshot with bitmap copying
