rust-cpython: prepare for writing tests that require libpython
What I wanted is to disable the "cpython/extension-module<ver>" feature
while building tests executable, but that seems not doable. Instead,
this patch adds new features dedicated for tests.
The make rule is extracted so that we can easily run cargo tests.
Added a minimal test of ref-sharing as an example. More tests will follow.

"""Generate release notes from our commit log.
This uses the relnotes extension directives when they're available,
and falls back to our old pre-relnotes logic that used to live in the
release-tools repo.
