handle changes in bison 3.x
* acinclude.m4 (OCTAVE_PROG_BISON): Also check for the proper way to
declare api.prefix.
* build-aux/common.mk (BISON_API_PREFIX_DECL_STYLE): New variable.
* lex.ll: Conditionally define YYSTYPE.
* oct-parse.in.yy (%API_PREFIX_DECL%): Allow for differences in the
way api.prefix is specified in different versions of bison.
* libinterp/parse-tree/module.mk (parse-tree/oct-parse.yy): Also
substitute %API_PREFIX_DECL% in lex.ll.
