	* app/config/gimpconfig.[ch]: added user_data pointer to serialize
	and deserialize methods.

	* app/config/gimprc.[ch]: implement gimp_rc_save() using
	gimp_config_serialize() so it can take advantage of the file
	handling magic implemented there.

	* app/config/test-config.c
	* app/core/gimp-documents.c
	* app/core/gimp-parasites.c
	* app/core/gimpdocumentlist.c
	* app/core/gimpparasitelist.c: changed accordingly.
