* Migrate the outbound packets from a central component to the individual
      per-peer components, substantially cutting down on lock contention when
      dealing with higher degrees.
    * Load balance the outbound SSU transfers evenly across peers, rather than
      across messages (so peers with few messages won't be starved by peers
      with many).
    * Reduce the frequency of router info rebuilds (thanks bar!)
