Backport of PEP 538: Coercing the legacy C locale to a UTF-8 based locale

Browse Source 
Fedora self-contained change: https://fedoraproject.org/wiki/Changes/python3_c.utf-8_locale

Since the backport is based on some changes done for the bpo-24932, these changes were backported as well
with the 261 patch, which will be removed when python3 is rebased to 3.6.1

+ attempt to configure one of the following locales for the given locale
+ categories before loading the interpreter runtime:

+ * ``C.UTF-8` (``LC_ALL``)
+ * ``C.utf8` (``LC_ALL``)
+ * ``UTF-8` (``LC_CTYPE``)
+
+ If setting one of these locale categories succeeds, then the matching
+ environment variables will be set (both ``LC_ALL` and ``LANG`` for the
+ ``LC_ALL`` category, and ``LC_CTYPE`` for the ``LC_CTYPE`` category),
+ and (if not already set to a non-empty string) :envvar:`PYTHONIOENCODING`
