Currently, dirty bitmaps are for internal use only


As I said, that's not correct: for external use we have bitmap export through 
NBD protocol.

Protocol description is here 
https://github.com/NetworkBlockDevice/nbd/blob/master/doc/proto.md  (you need 
"Metadata querying" section)

And qemu bitmap export through NBD "metadata querying" feature is described 
here: docs/interop/nbd.txt
