Replacing autotools with meson

[sp1ritCS]

Hey, I've written a meson build script for cpython and was wondering if there is any interest in upstreaming this. Figured I ask here first before going to the trouble of writing a PEP for it.

The changeset can be seen here: sp1ritCS@meson~0, while its not fully ready (some evaluations missing, no pyc generation for Lib, getpath.py not coping with the freestanding build dir, ...), it builds on my machine (Linux) and with a bit hacking (libffi&openssl subprojects need gnu std) its able to build on Android too. Besides the mile-long evaluation section (some of these might be unused and could be pruned, but I mostly tried to follow what configure was doing) I'm fairly happy with it.

Hello, thanks for sharing your work! We have a discussion thread about possibly changing the build system, and Meson is a candidate.

Would you like to share your findings in the thread?

Let's continue there and close this issue for now, until a decision is made. Thanks!
