Move some declarations in the raw-parser header files to create a clearer
distinction between the external API (parser.h) and declarations that only need to be visible within the raw parser code (gramparse.h, which now is only included by parser.c, gram.y, scan.l, and keywords.c). This is in preparation for the upcoming change to a reentrant lexer, which will require referencing YYSTYPE in the declarations of base_yylex and filtered_base_yylex, hence gram.h will have to be included by gramparse.h. We don't want any more files than absolutely necessary to depend on gram.h, so some cleanup is called for.
