tracing: New macro to set up initial event flags value
This introduces the new TRACE_EVENT_FLAGS() macro in order
to set up initial event flags value.
This macro must simply follow the definition of a trace event
and take the event name and the flag value as parameters:
TRACE_EVENT(my_event, .....
....
);
TRACE_EVENT_FLAGS(my_event, 1)
This will set up 1 as the initial my_event->flags value.
