revlog: using two new functions in C capsule from Rust code
We expose `index_length` and `index_node` in the C capsule, so that
the Rust representation of the C index can implement the `RevlogIndex`
trait.
Because our `Node` is actually a one-field struct, we have
to decorate it for direct FFI exchange with the C `char*`
It would be a good thing to get a length from the C layer, but doing
so right now would probably interfere with the upcoming changes that
will happen there for the hash length.

nodemap: refresh the persistent data on nodemap creation
The logic to read the data and validate the docket are still in python, so we
need to "help" whatever compiled code live in the index to refresh it.
Otherwise clearing the cache could lead to an expensive full recomputation and
disk update even when the persisted data are still valid.

git: skeleton of a new extension to _directly_ operate on git repos
This is based in part of work I did years ago in hgit, but it's mostly
new code since I'm using pygit2 instead of dulwich and the hg storage
interfaces have improved. Some cleanup of old hgit code by Pulkit,
which I greatly appreciate.
test-git-interop.t does not cover a whole lot of cases, but it
passes. It includes status, diff, making a new commit, and `hg annotate`
working on the git repository.
This is _not_ (yet) production quality code: this is an
experiment. Known technical debt lurking in this implementation:
* Writing bookmarks just totally ignores transactions.
* The way progress is threaded down into the gitstore is awful.
* Ideally we'd find a way to incrementally reindex DAGs. I'm not sure
how to do that efficiently, so we might need a "known only fast-forwards"
mode on the DAG indexer for use on `hg commit` and friends.
* We don't even _try_ to do anything reasonable for `hg pull` or `hg push`.
* Mercurial need an interface for the changelog type.
Tests currently require git 2.24 as far as I'm aware: `git status` has
some changed output that I didn't try and handle in a compatible way.
This patch has produced some interesting cleanups, most recently on
the manifest type. I expect continuing down this road will produce
other meritorious cleanups throughout our code.

For downstream projects which are using Mercurial’s test infrastructure and are
