Added a get_objects_in_range() method. Takes in a time range and the type

2000-08-08  Federico Mena Quintero  <federico@helixcode.com>

	* idl/evolution-calendar.idl (Cal): Added a get_objects_in_range()
	method.  Takes in a time range and the type of component we are
	interested in; returns a list of UIDs.  The idea is that
	ocurrences get computed in the client; we can have multiple
	recurrences in iCalendar and we cannot identify them trivially
	across the wire.
	(Cal): Removed the get_events_in_range() method.

	* pcs/cal-backend.c (cal_backend_free_uid_list): New function.
	(cal_backend_get_objects_in_range): New function.
	(cal_backend_get_events_in_range): Removed.

	* pcs/cal-backend-file.c (cal_backend_file_get_objects_in_range):
	Implemented new method.
	(cal_backend_file_get_events_in_range): Removed.

	* pcs/cal.c (Cal_get_events_in_range): Removed.
	(uncorba_obj_type): New function.
	(Cal_get_uids): Use uncorba_obj_type().
	(Cal_get_n_objects): Likewise.
	(Cal_get_objects_in_range): Implemented new method.

	* cal-client/cal-client.c (cal_client_get_events_in_range): Removed.
	(cal_client_get_objects_in_range): Implemented.
	(corba_obj_type): New function.
	(cal_client_get_n_objects): Use corba_obj_type().
	(cal_client_get_uids): Likewise.
