for speed and to reduce object churn
  * FragmentedMessage cleanup

    - Move from core to router/transport
    - Make non-static, instantiate in TransportManager
    - Generate keypair in constructor and make final
      to move more processing to the precalc thread
      and eliminate races
    - Synchronize getSessionKey() to eliminate races
    - Comment out unused methods
  * UDPTransport:
    - Make key builder final in InboundEstablishState to

    instead of a ContextHolder, ServletHandler, and ServletHolder.
    This also fixes / which returned a zero-length file,
    broken in the last checkin.

    instead of ResourceHandler, to provide resume, directory
    indexes, caching, etc.

    - Don't use unacked tagsets after consecutive ack failures
      and revert to full ElGamal if necessary (ticket #574)
    - Synchronize creation of new sessions to prevent dups
    - Don't remove an unacked session until it's really out of tags
    - Failsafe removal of old unacked tagsets
    - Cleanups, final, comments, log tweaks, debug.jsp tweaks, synchronization tweaks

    caused by last checkin (symptom: i2psnark in wrong directory)

  - AJAX fixes
  - Translate 'router is down' message

    - StoreState finals

    - Remove static logs
    - Sort addresses in RouterInfo at initialization only;
      change from Set to List to save space

    - Increase max leases to 16

checkin comments claim it was reenabled in 0.7.10
but it didn't actually happen, probably due to bad merge.

    inbound tunnels to improve success
  * NetDB:
    - Don't publish our RI if it has no addresses
    - Publish our RI sooner after startup
      to facilitate our IB tunnel builds

      (ticket #599)
