From: Jeff Hostetler <jeffhost@xxxxxxxxxxxxx> Teach the message formatter in the Trace2 event target to take an optional thread-name argument. This overrides the thread name inherited from the thread local storage data. This will be used in a future commit for global events that should not be tied to a particular thread, such as a global stopwatch timer that aggregates data from all threads.
