1. materialize: don't use locks in the extended logger …

   The use of a mutex in both the extended logger event handler and the async
   logger functions was simple, but there was a potential deadlock if the event
   handler needed to stop the logger and wait for it to stop while holding the
   lock, and the logger timer ticked over at nearly the same instant making the
   logger need to get the lock also to finish its last log before exiting.
   
   This updates the extended logger to not use locks at all, since it wasn't far
   from being able to do that in the first place. The "count" values that are read
   concurrently by the async loggers have been changed to use atomics, and for good
   measure the "round" counter is provided as an explicit argument to them, even
   though it doesn't strictly need to be, it's just easier to understand this way.
