Well, 'fnmatch' and 'regex' uses iswctype and wctype. So, we need to have
counterparts of these functions in the char32_t world.

Since the ISO C names are idiosyncratic, let me choose more regular
identifiers:

  wchar_t             char32_t
  -------             --------

  iswctype            c32_apply_type_test
  wctype              c32_get_type_test
