[issue45247] Add explicit support for Cython to the C API.

[Mark Shannon]

New submission from Mark Shannon <mark at hotpy.org>:

As the C API has evolved it has grown features in an ad-hoc way, driven by the needs to whoever has bothered to add the code.

Maybe we should be a bit more principled about this. Specifically we should make sure that there is a well defined interface between CPython and the other major components of the Python ecosystem.
The obvious places to start are with Cython and Numpy.

This issue deals specifically with Cython. I will leave it to someone who know more about Numpy to open an issue for Numpy.
