Since there will shortly be multiple event groups allowed, we can no longer use the TraceEventID and TraceEventVCPUID enums in the trace control APIs. There will in fact be multiple distinct enums, and the enum values will only be required to be unique per group. Signed-off-by: Daniel P. Berrange

Instead of having a global dstate array, declare a single 'uint16 TRACE_${EVENT_NAME}_DSTATE' variable for each trace event. Record a pointer to this variable in the TraceEvent struct too. By turning trace_event_get_state_dynamic_by_id into a macro, this still hits the fast path, and cache
