Renamed from backend_destroy_cb. Now we use it for the "last_client_gone"

2000-04-25  Federico Mena Quintero  <federico@helixcode.com>

	* pcs/cal-factory.c (backend_last_client_gone_cb): Renamed from
	backend_destroy_cb.  Now we use it for the "last_client_gone"
	signal from the backend.  Also, unref the backend to destroy it.
	(add_backend): Connect to the "last_client_gone" signal of the
	backend.
	(cal_factory_get_n_backends): New function to query the number of
	running backends.

	* pcs/cal-backend.c (cal_backend_class_init): Register the new
	"last_client_gone" signal.  It is emitted when the last Cal client
	goes away.  It is used to notify the factory when a backend may be
	safely destroyed.
	(cal_destroy_cb): Emit the "last_client_gone" signal when the last
	client disconnects from the backend.
