Original change's description:
> Handle iframe touch ack time out
> 
> When there is a touch ack time out, all the gesture events will be flushed
> to the touch action filter. This case is already taken care of in the
> non-iframe case, and this CL handles the iframe case.
> 
> When we see that a gesture event is flushed due to time out, we set the
> effective touch action to auto which will allow all the gesture event.
> A browser test is added to ensure the correctness.
> 
> This CL is break into few patches:
> PS#22: The essential fix in line 1190 in the
> render_widget_host_input_event_router.cc is commented out. When running the
> newly added browser test, it will hit the DCHECK in touch_action_filter.cc
> at line 55.
> 
> PS#23: Uncomment the essential fix in the
> render_widget_host_input_event_router.cc and remove the DCHECK in
> touch_action_filter.cc at line 55. Uncomment the temporary fix in
> touch_action_filter.cc for bug 851664.
