Simplify implementation of unqualified %code, implement macros for
	uniform treatment of boolean %define flags.  Document %define.
	* data/bison.m4 (b4_percent_define_ifdef, b4_percent_define_flag_if,
	b4_percent_code_ifdef): New.
	(b4_percent_code_get): Map unqualified %code to b4_percent_code().
	* data/c++.m4: Define default value for global_tokens_and_yystype.
	* data/glr.cc: Likewise.
	* data/location.cc: Use b4_percent_define_flag_if.

	* doc/bison.texinfo (Directives): Document %define.

	* src/parse-gram.y (Unqualified %code): Change muscle name to
	b4_percent_code().
	(content.opt): Default to empty.
