* glib/dbus-gidl.c (method_info_add_arg): keep args sorted with
	"in" before "out"

	* glib/dbus-gobject.c (dbus_type_to_string): move to dbus-gutils.c

	* glib/dbus-glib-tool.c (main): set up to have a --self-test
	option that runs the tests, and start filling in some code
	including for starters just dumping the interfaces to stdout

	* glib/Makefile.am (INCLUDES): define DBUS_LOCALEDIR

	* test/data/valid-introspection-files/lots-of-types.xml: test of
	an example introspection file

	* glib/dbus-gparser.c (parser_check_doctype): doctype should be
	"node" (I think...)
