[Python-Dev] Official port of Python on EDK2

UEFI has become the standard for firmware (BIOS) interface. Intel has
provided an open source implementation under the name EDK2 (part of
the TianoCore initiative) [1] for some time. This implementation has
evolved significantly and now provides the functionalities of a small
OS with a standard library similar to POSIX.

In 2011, a port of Python 2.7.1 was added to the EDK2 repository [2].
This port then evolved to 2.7.2 which is still defined as the
reference port [3]. In 2015, another port was added of Python 2.7.10
in parallel of 2.7.2 [4]. Since then, both implementations have
diverged from upstream and know vulnerabilities have not been fixed.

I would like to bring support for edk2 in the official Python
repository to remediate this situation, that is officially support
edk2 as a platform. Technically, there would be three main aspects for
the on-boarding work:

1) Fix headers and source to resolve definition conflicts, similarly
to ABS definition in [5];
2) Add the edk2module.c [6] to handle platform-specific
functionalities, similarly to the posixmodule.c;
3) Add the build configuration file [7] and necessary modifications
within Python to handle the edk2 toolchain;

This work would target the master branch (that is Python 3). I would
be interested in hearing your thoughts on this idea.
