bug 1172525 - rework forwarding events to the parent process r=davidb, lsocks

Browse Source 
The set of events fired to platform accessibility is not the same as the set in
the event queue.  Therefore we should forward events to the parent process
someplace where they are the same so the same events can be emitted for child
processes.
