[bug-gettext] [PATCH] intl: Port to Bison 3.0

[Daiki Ueno]

* gettext-runtime/intl/plural.y: Don't use removed YYLEX_PARAM and
YYPARSE_PARAM macros; replace deprecated %pure_parser with
'%define api.pure full'; adjust yylex/yyerror arglist.
* gettext-runtime/intl/plural-exp.h (PLURAL_PARSE): Use explicit type
'struct parse_args *arg' for ARG.
