Register the X11 connection fd in the input system so that mp_input_get_cmd() can immediately wake up and handle keyboard or other X events. The callback calls vo_check_events() and tells the input system to handle any input possibly recorded during that. Before this was done for vo_xv only; this commit generalizes it to all VOs that call vo_x11_create_vo_window() - those are hopefully ones that will handle all X events in check_events(). The callback is only kept registered while the vo is properly configured. At other times calling check_events() would not clear pending input and so could lead to a busy loop.
