On the Road to Irmin v2

In order to seamlessly integrate with Irmin, we embarked on an effort to build a complete re-implementation of Git from scratch in pure OCaml. If you get a chance to try ocaml-git in your infrastructure, please let us know how you get along as we prepare a release of the git libraries with all these fixes (which will be used in Irmin 2.0). Crucially, because of the way Irmin is split into clean libraries and OCaml modules, we only had to modify a small part of the codebase and could also re-use elements of the Git 2.0 engineering effort we described above.
