Durham Goode bf3cad3004 hggit: store git hash in hg extras
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.

This commit is called gamma10 so that its hash will have the same initial digit
as commit alpha. This lets us test ambiguous abbreviated identifiers.
