I'll see what I can do. I needed to re-roll after discovering an issue
when trying to integrate the algorithm with shallow clones. The solution
ends up simplifying the code, which is nice.

In the current series, there's a natural cut between patches 1-4
and the rest, if we want to put the API in without a non-test consumer.

I could also split out the 'git repack' changes into a third series.

Finally, the threading implementation could be done separately, but I
think it's not complicated enough to leave out from the first version
of the --path-walk option in 'git pack-objects'.
