before stop tracing, write remaining trace messages


I think that when you stop tracing, it should be better to first write all remaining trace messages to the log file (if the logwriter exists). From what I've seen from testing, this doesn't happen now.

E.g. when I stop tracing to log file, I first trace a message 'tracing disabled', but this never shows in the log file.
(unless I enable file tracing again, but that's not the behaviour I expect).

The following might solve the problem of writing remaining messages to the log file, when I stop file tracing :

I added the following static method to the Tracer :
public static void FlushTrace()
I my own method to stop file tracing I then do the following:
            _traceLogFileWriter = null;
This seems to work, could you verify I this might introduce other issues esp. concerning multithreading?

I solved the problem by adding a Flush() method to Tracer. I also added AddMessagesTracedListener() and RemoveMessagesTracedListener() to properly administer event handlers. The parameter needsFlushing is per default true when calling RemoveMessagesTracedListener().

In TraceLogFileWriter I implemented a proper Dispose() and destructor, which will flush Tracer to get all messages.
