Fix performance regression in addremove command.
When I rewrote addremove, I lazily put a call to repo.changes in,
which was unnecessary and slow. This is a new rewrite, preserving the
file name behaviour, but replacing the call to repo.changes with a walk,
which is much cheaper, and avoids calls to os.stat on all but files that
have probably been deleted.
