Description

Currently __ctype_mask, __translower, and __transupper are defined as pointers to __runetype, __maplower, and __mapupper, respectively, in _DefaultRuneLocale, so once we call setlocale() with any UTF-8 locale as argument (which in turn calls install_legacy()), the contents of _DefaultRuneLocale are overwritten with those from UTF-8 locale.

This breaks character handling functions if we then switch back to C locale.

We should simply define those as separate objects, and initialize them to be the same as corresponding members of _DefaultRuneLocale, initially.
