Input: evdev - indicate buffer overrun with SYN_DROPPED
Add a new EV_SYN code, SYN_DROPPED, to inform the client when input
events have been dropped from the evdev input buffer due to a
buffer overrun. The client should use this event as a hint to
reset its state or ignore all following events until the next
packet begins.

[dtor@mail.ru: Implement Henrik's suggestion and drop old events in
case of overflow.]
