* girepository/girnode.c: Allow gtype_name

	* girepository/girparser.c: Parse glib:
	boxed bits for both structure and union.

	if structure is boxed.
	* giscanner/girparser.py: Parse new XML
	format.
	* giscanner/girwriter.py: Write out new
	XML format.
	* giscanner/glibast.py: Define new classes
	which are both Boxed and Struct/Union, as
	well as an "Other" for everything else.
	* giscanner/glibtransformer.py: Handle
