changegroup: don't support versions 01 and 02 with treemanifests
Since it would be terribly expensive to convert between flat manifests
and treemanifests, we have decided to simply not support changegroup
version 01 and 02 with treemanifests. Therefore, let's stop announcing
that we support these versions on treemanifest repos.
Note that this means that older clients that try to clone from a
treemanifest repo will fail. What happens is that the server, after
this patch, finds that there are no common versions and raises
"ValueError: no common changegroup version". This results in "abort:
HTTP Error 500: Internal Server Error" on the client.
Before this patch, it was no better: The server would instead find
that there were directory manifest nodes to put in the changegroup 01
or 02 and raise an AssertionError on changegroup.py#668 (assert not
tmfnodes), which would also appear as a 500 to the client.
