If lock is not None, the function takes ownership of the lock
and releases it after the changegroup is added.
Return an integer summarizing the change to this repo:
- nothing changed or no source: 0
- more heads than before: 1+added heads (2..n)
- fewer heads than before: -1-removed heads (-2..-n)
- number of heads stays the same: 1
