* 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...)
