Summary:
In order to move our hg-git mirroring off of the main hg servers, we
need to make it possible for the hg servers to compute the hg-git mapping
without having the entire git repository available. To do so, let's store the
git hash as an extra in the hg commit.
This breaks bidirectionality, but we've long since not needed that.

Summary:
Previously hggit used a single transaction for each commit it imported.
This added a lot of over head, such as writing the fncache every time and
committing to sql every time.
Instead, let's use a transaction that lasts a while. We'll tie it to the
existing gitmap save logic, so that we commit commits to disk before writing the
map file (so the map file never references commits that don't exist).

Summary:
The hg servers were having trouble bootstrapping the .hg/git directory
because hggit was creating a bare repo and then later git fetches were super
slow. Those .hg/git directories should be managed by infra outside of hg, so
let's add a config knob to prevent hggit from creating a .hg/git repo.
