     shutdown the whole router when ooming.

   - Better handling of 504 gateway timeout
     (keep going up to limit of retry count rather
      than just one more partial fetch)
   - Add -t cmd line option for timeout
   - Better handling of 403, 409, 503 errors
   - Don't keep going after unknown return code
   - Don't delay before exiting after a failure

    - Don't create SnarkManager instance until first call,
      so it doesn't create the i2psnark dir, read the config,
      etc., for single Snark instances.
    - Don't read i2psnark.config twice; fix setting
      i2psnark.dir
    - More Snark constructor changes for calling from router
    - Make max connections per torrent configurable

    - Use new I2PAppThread that does not call global listeners on OOM,
      so that OOMing apps will not shutdown the whole router.

    - Remove static instances of I2PSnarkUtil, ConnectionAcceptor,
      and PeerCoordinatorSet
    - Convert static classes in Snark to listeners
    - Fix Snark to work in single torrent mode again
    - Should now work with multiple single Snarks

  - Refactor to allow running a single Snark without a SnarkManager again,
    by moving some things from SnarkManager to I2PSnarkUtil,
    having Snark call completeListener callbacks,
    and having Storage call storageListener callbacks.
    This is in preparation for using Snark for router updates.
    Step 2 is to allow multiple I2PSnarkUtil instances.
  - Big rewrite of Storage to open file descriptors on demand, and
    close them when unused, so we can support large numbers of torrents.
