purer setuptools

[arthurzam]

As part of pkgcore/snakeoil#77 , use purer setuptools setup. Some of the big changes:

1. Wheel are python ABI agnostic. While platform specific, they don't link/include python stuff (just tree-sitter-bash), so the library is python agnostic, and we can create a "universal" wheel per platform.
2. I use new snakeoil sphinx extension for man/html generation - removes all logic from doc/conf.py
3. Add CI workflow to release.yml to create platform wheels for arm64, ppc64le, s390x, for both musl and glibc
4. Add makefile for easier work with the various commands
5. Enable testing directly using pytest command, and not using setup.py test

Just a cursory look for now.

Do you need the explicit wheel dep?

[arthurzam]

Surprisingly enough, I do indeed use wheel, to mark my wheel as python ABI agnostic
The usage is with the line:

from wheel.bdist_wheel import bdist_wheel as orig_bdist_wheel

...

class bdist_wheel(orig_bdist_wheel):
    ...
