  1. adjust sleep module API to have an IdleState object 

    This makes the "idle state" private to the sleep module.

  2. port to the new log api 

    This involves:

* creating a `Logger` object (always)
* using `logger.log(|| ...)` instead of a macro
    * if logs are not compiled in, this should be optimized away
* the logger tracks the number of active threads in various states etc
* some log event names were "normalized" to be more consistent
