os_mbcs.patch adds _Py_EncodeCodePage() to encode directly wchar_t* filenames without having to create a temporary Unicode object.

The patch removes HAVE_MBCS because the MBCS is now always needed by the posixmodule.c. Anyway, I don't see why MultiByteToWideChar() and WideCharToMultiByte() would not be available on Windows.
