Design a new better C API for Python

This project is a fork of the development version of the future CPython 3.8. The intent is to experiment to implement the new C API described at:

https://pythoncapi.readthedocs.io/

Install dependencies on Fedora:

dnf install -y make gcc check

Build and run unit tests:

./configure --enable-shared --with-pydebug
make
cd capi_tests
make
