Called when the main frame changes due to (a) initial browser creation, (b) final browser destruction, (c) cross-origin navigation or (d) re- navigation after renderer process termination (due to crashes, etc). |old_frame| will be NULL and |new_frame| will be non-NULL when a main frame is assigned to |browser| for the first time. |old_frame| will be non-NULL and |new_frame| will be NULL and when a main frame is removed from |browser| for the last time.
