These should still occur, they do in most programs or GTK wouldn't
work at all. "window" is a GtkWindow, right?

The easiest path is to just keep using gtk_signal_connect(), it's not
actively harmful to do so.

Other than that the mapping is:

 gtk_signal_connect -> g_signal_connect
 gtk_signal_connect_after -> g_signal_connect_after
 gtk_signal_connect_object -> g_signal_connect_swapped
 gtk_signal_connect_while_alive -> g_signal_connect_object

The last two are confusing since the meaning of "object" was
rationalized (it previously meant "swapped", now it means "the user
data is an object so set up while alive connections")
