The TraceEvent struct contains a "bool sstate" field which track whether
a trace event was disabled statically. i.e. at build time via the
"disable" property annotation in trace-events.
The only runtime use of this field is to let "trace-event-get-state"
report that an event is "unavailable" instead of reporting an error for
an unknown trace event.
Trace events are not ABI so their names can change and the event can
come and go at any time. Thus there is little utility in reporting the
existence of a disabled event that cannot ever be used at runtime.
Removing the "bool sstate" field from TraceEvent saves 8 bytes of
space in the struct, adding up to approx 64 KB across all current
events.
