Update.

	* catgets/open_catalog.c: Rewrite code to assume that the function
	is called at catopen time and not delayed in catgets.
	* catgets/catgets.c (catopen): Call __open_catalog and fail if that
	function failed.
	(catgets): Remove code for delayed opening of catalog.
	* catgets/catgetsinfo.h: Remove now unnecessary information from
	struct catalog_info.  Change __open_catalog prototype.
	* catgets/gencat.c: Adjust __open_catalog call.
	* catgets/test-gencat.c: Stop program if catopen failed.
