Revert the changes made by commit v3.1.0-rc1~406^2~1 (Encoding: Add
setlocale() to applications, 2014-05-30) and commit v3.1.0-rc1~406^2
(Encoding: Change to only set LC_CTYPE, 2014-06-11), and other setlocale
calls added later in their spirit.  CMake has not been taught how to
deal with non-C locales everywhere.  We do not define any functionality
for character conversions for non-ASCII strings.  Another solution will
be needed to address the original problem motivating addition of
setlocale() calls.
