    Don't attempt to unload locale context data
    
    Most locale context users call _XlcCurrentLC, which returns a pointer
    which never needs to be passed to _XCloseLC, meaning it has unbounded
    lifetime, so that locale data can never be freed.
    
    Remove all reference counting and just leave all locales that were
    ever used in memory.

    The way it's currently cached is not thread safe. As long as locale doesn't change, the same object is reused anyway.

commit 7a38c09b82ee2522d987c3da4af8af186e562c61

    Don't cache converters in _Xlcmbtowc and Xlcwctomb
    
    These functions were caching encoding conversion functions in static
    variables which is not thread safe. Let the conversion loader do its
    job and cache locale to converters there. It's less efficient, but
    it's also (now) thread safe.
