    * Tweak the PRNG logging so it only displays error messages if there are
      problems
    * Disable dynamic router keys for the time being, as they don't offer
      meaningful security, may hurt the router, and makes it harder to
      determine the network health.  The code to restart on SSU IP change is
      still enabled however.
    * Disable tunnel load testing, leaning back on the tiered selection for
      the time being.
    * Spattering of bugfixes
