Subject: ntsync: Introduce NTSYNC_IOC_EVENT_PULSE.
This corresponds to the NT syscall NtPulseEvent().
This wakes up any waiters as if the event had been set, but does not set the
event, instead resetting it if it had been signalled. Thus, for a manual-reset
event, all waiters are woken, whereas for an auto-reset event, at most one
waiter is woken.
