Subject: Utility wrapper around icalparser.

	* cal-util/cal-util.c (cal_util_parse_ics_file): Utility wrapper
	around icalparser.

	* cal-util/test-recur.c (main): Use it

	* pcs/cal-backend-file.c (open_cal): Likewise

	* gui/comp-editor-factory.c (open_client): Add the OpenClient to
	the hash before calling cal_client_open_calendar, since in some
	failure cases, that will call cal_opened_cb (which will free the
	oc) with a failure immediately, causing a crash if we then try to
	deref it.
