Return the event's data when EV_ERROR is set in its flags and 0 otherwise, as KytyPS5 does and as FreeBSD 11 kevent stores the errno of a failed change. A null event throws like the other accessors.
Document the level-triggered user event semantics of sceKernelWaitEqueue in TechnicalDebt.
(cherry picked from commit db79bee1e597effff34c72493ed893d4e750b95d)
A user event added with sceKernelAddUserEvent stays triggered until it is
deleted. The collection loop kept re-emitting it until the caller's event
buffer was full, so a wait with num > 1 returned the same event num times.
Like kevent, each event is now reported at most once per call; distinct
queued completions of one event are still delivered in order.
(cherry picked from commit db28ebbb7f078cb593cf6b7bb34b8db49dd94630)
sceKernelGetEventId, sceKernelGetEventFilter, sceKernelGetEventFflags,
sceKernelGetEventData and sceKernelGetEventUserData return the matching
field of the KernelEvent filled by sceKernelWaitEqueue and throw on a
null event. sceKernelGetEventError still throws NotImplemented.
