Attempted locale refactoring. _LIBCPP_LOCALE__L_EXTENSIONS now should be defined if one has all of the xxx_l() functions. I've defined this for apple, freebsd and win32. _LIBCPP_HAS_DEFAULTRUNELOCALE should be defined if there is a _DefaultRuneLocale. I've defined this for apple and freebsd. The block of code we're trying to migrate away from is now under #ifdef __linux__. I've tested only on OS X. I hope I haven't broken things too badly elsewhere. Please let me know.
