setup.py: Add codecs and locale hacks

[jayvdb]

There are a few obscure hacks needed in setup.py to avoid breakages, and typically projects dont do these, as they are not exposed to cases where it is important.

coala has a few which need to be brought upstream here.

https://gitlab.com/coala/coala-bear-management/commit/516b50c33c8fdb0f5ad02019d9092cc1059d907d includes a hack working around https://bugs.python.org/issue10945 , for Python < 3.4 and needs to be commented as that. Ideally we would not include this hack for projects which dont support Python 3.3 or lower

https://gitlab.com/coala/mobans/blob/master/templates/coala-setup.py.jj2#L34 contains a workaround for locale not being set, which especially causes problems when installing on raw docker images.

The solution in #60 is wrong, as it mixes jinja logic (setup.py build) and installer logic (setup.py runner) which are two different environments. The code needs to be in setup.py if project supports any effected version, and the comments about it should not be included when zero effected version are supported.

Another version of the hack

# Workaround for mbcs codec bug in distutils

import codecs
try:
	codecs.lookup("mbcs")
except LookupError:
	codecs.register(lambda name: codecs.lookup("ascii") if name == "mbcs" else None)
