    Fixes to collate facet and test enhancements:

    * src/collate.cpp (__rw_strnxfrm): corrected processing of
      embedded NULs. (__rw_wcsnxfrm) same (duplicated code).
      (collate_byname<wchar_t>::do_compare): fixed string comparison
      return values, re-implemented the wcscoll-based comparison.
    * tests/localization/22.locale.collate.cpp: implemented a simpler
      collation test for strings with embedded NULs.
