stream-clone: implement decidated `get_streams` method for revlog
For revlog, we can do better using the maximum linkrev expected. This approach
open the way to dealing with a much larger set of non-trivial changes, like
splitting of inline revlogs.
We will actually tackle this issue in the next changesets (thanks to this one).
