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.

hg-core: add a compilation error if trying to compile outside of Linux
For now, we can only provide support for Linux in `hg-core`, so we have to be
explicit about it in case anyone wonders why their Dirstate is suddenly broken,
or why the crate does not compile (on Windows for example).

gzip: use the stdlib version with python 3 (
issue6284)
It turned out that the stdlib gained the feature we missed in python 3.1. We can
now use it directly.
gzip: indent the custom Gzip code
We need a new conditional in the next changesets (Adding 3.8 support). We do the
large code move beforehand for clarity.
gzip: rename the argument to `mtime` to match upstream python
Python gained the feature we missed in 3.1. The argument name is `mtime`. We
align our version for consistency.
heptapod-ci: run the test from outside the test directory
This will help detecting case where this is broken.
run-tests: fix conditional when tests are run outside of `tests`
The logic to find `hghave` was using `__file__` but… non absolute path in
`__file__` gets wrong as soon as we change directory (thanks python… you are
being helpful). The rest of the `run-tests.py` code already deal with this
fine. We simply reuse the `RUNTESTDIR` variable to fix it.
