    glib/tests/utf8-validate: test known-length case along with null-terminated
    
    For all test cases where the text length is given as -1, also
    call g_utf8_validate() with the actual string length to exercise
    the known-length case. Unknown-length and known-length validation
    use different code paths, but most of the tests only exercised with
    unknown-length parameter.
