dagop: extract DAG local heads functionality from revlog

As part of implementing an alternate storage backend, I found myself
having to reimplement this function.

The DAG traversal logic is generic and can be factored out into a
standalone function.

We could probably combine this with headrevs(). But I'll leave that
for another time.
