Are there any downsides of doing this? I know we've put a lot of work
into cozying up with internal git utility functions and their build
system. Would we have to reimplement a lot of this? Would it be worth
it? Are there general benefits of using libgit2 over what we have now?
Are there general downsides?

More importantly, is this something you would be willing to do, if we
decided it was the best direction?
