changed getFreeBusy method to return a CalObj instead of a sequence

2001-06-22  Rodrigo Moya <rodrigo@ximian.com>

	* idl/evolution-calendar.idl: changed getFreeBusy method to return
	a CalObj instead of a sequence

	* cal-client/cal-client.[ch] (cal_client_get_free_busy): changed it to
	work like the cal_client_get_object function, that is, it does not
	return anymore a list of UIDs, but a CalClientGetStatus code, and
	added a new parameter for the caller to get the component back when
	this function returns
	(cal_client_open): aggregate WombatClient interface to the CalListener
	being used

	* pcs/cal-backend-db.c, pcs/cal-backend-file.c (..get_free_busy): set
	return value to "char *" as it will be returning a FreeBusy object,
	and not a list of UIDs

	* pcs/cal-backend.[ch] (cal_backend_get_free_busy): ditto

	* pcs/cal.c (cal_construct): queryInterface on the listener to obtain
	the WombatClient interface
