For the locale refactor, the locale management functions (newlocale, freelocale, uselocale) are needed in a separate header from the various _l functions. This is because some platforms implement the _l functions in terms of a locale switcher RAII helper, and the locale switcher RAII helper needs the locale management functions. This patch helps pave the way by getting all the functions in the right files, so that later diffs aren't completely horrible. Unfortunately, the Windows, Cygwin, and MinGW builds seemed to have bit-rotted, so I wasn't able to test this completely. I don't think I made things any worse than they already are though. http://reviews.llvm.org/D17419 git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@263020 91177308-0d34-0410-b5e6-96231b3b80d8
