block: More operations for meta dirty bitmap
Callers can create an iterator of meta bitmap with
bdrv_dirty_meta_iter_new(), then use the bdrv_dirty_iter_* operations on
it. Meta iterators are also counted by bitmap->active_iterators.
Also add a couple of functions to retrieve granularity and count.
