See earlier comment re not splitting clipboard_stub from input_stub at this
level just yet.

Now that InputStub doesn't inherit from ClipboardStub, I think these can stay
separate. But they could merge to a set_host_event_stub(), if that's clearer.

   virtual void set_host_stub(HostStub* host_stub);
   virtual void set_input_stub(InputStub* input_stub);
 
  private:
   // Callback for protocol Session.
   void OnSessionStateChange(Session::State state);
