Log message:
        GLR parsers sometimes raise parse errors instead of performing the
        default reduction.
        Reported by Charles-Henry de Boysson.
        * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
        check the length of the traces when %glr.
        (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
        GLR's traces.
        (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
        Test GLR parsers.
        * data/glr.c (YYLEFTMOST_STATE): Fix its value.
        (yyltype): Remove the yy prefix from the member names.
        (yytable): Complete its comment.
        (yygetLRActions): Map error action number from YYTABLE from
        YYTABLE_NINF to 0.
        (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
        (which was a bug: it should have been YYTABEL_NINF, and yet it was
        not satisfying as we could compare an YYACTION computed from
        YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
        only value for error actions.
        (yyreportParseError): In verbose parse error messages, don't issue
        `error' in the list of expected tokens.
        * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
        next action to perform to match glr.c's decoding.
        (yytable): Complete its comment.
