Writing warnings to stderr causes many test failures and the warning
cannot be disabled.

@ncoghlan: So Nick, what do you think? :-)

bpo-30565: Remove PEP 538 warnings
1a81aeb 
Writing warnings to stderr causes many test failures in the Python
test suite, warning which could only be disabled when building Python
but not at runtime.

Remove also --with(out)-c-locale-warning option of configure and
PY_WARN_ON_C_LOCALE define.

I don't understand the AppVeyor failure :-( I'm not sure that it's related to my PR.

I'm fine with making the stderr warnings opt-in at runtime via PYTHONCOERCECLOCALE=warn, but I'm not a fan of removing them entirely.

With the off-by-default runtime switch, you could still remove the compile time option, though.

I'm not a fan of this approach, so I'll put together an alternative PR that instead adds PYTHONCOERCECLOCALE=warn as a runtime guard for both the successful coercion warning and for the coercion-failed-or-was-not-attempted warning, while remove the build time option.

@Haypo +1'ed #2260, so closing this in favour of that PR.
