to reduce object churn, we only need one
Add DeliveryInstructions.create() to return immmutable
local instructions, to reduce object churn
Minor cleanups

  - Comment out unused encryption fields to save space
  - New static immutable LOCAL instruction to reduce object churn

    - Deprecate unused stream methods and I2NPMessageReader since
      all transports provide encapsulation.
    - Don't throw IOE from byte array methods
    - Use cached null cert in GarlicClove
    - Add method to limit size of buffer to read
    - Don't check checksum at input, in most cases
    - Reuse checksum at output, for unomodified pass-through messages
      (but recalculating it now and logging on a mismatch for testing)
    - Fix DatabaseLookupMessage to internally store the don't include peers as
      a List, not a Set, so it doesn't get reordered and break the checksum
    - Log cleanup
  * NTCP:
    - Zero-copy and limit size when handing buffer to I2NP
    - Log hex dump message on I2NPMessageException, like in SSU
    - Don't close connection on I2NPMessageException

      - New SDSCache for SimpleDataStructures
      - New SimpleByteCache for byte[]
      - Cache Hash, PublicKey, and SigningPublicKey
      - Remove global lock in ByteCache

      for efficiency (thanks Arsene for the suggestion)

    * Code janator work, basic corrections involving @Override, and
      appling final where it is important. Also fixed some equals methods
      and commented places that need fixing.

    * Adjust the netDb search and store per peer timeouts to match the average
      measured per peer success times, rather than huge fixed values.
    * Optimized and reverified the netDb peer selection / retrieval process
      within the kbuckets.
    * Drop TCP connections that don't have any useful activity in 10 minutes.
    * If i2np.udp.fixedPort=true, never change the externally published port,
      even if we are autodetecting the IP address.
(also includes most of the new peer/NAT testing, but thats not used atm)

    * Use the small thread pool for I2PTunnelHTTPServer (already used for
      I2PTunnelServer)
    * Minor memory churn reduction in I2CP
    * Small stats update

    * Increase the tunnel test timeout rapidly if our tunnels are failing.
    * Honor message expirations for some tunnel jobs that were prematurely
      expired.
    * Streamline memory usage with temporary object caches and more efficient
      serialization for SHA256 calculation, logging, and both I2CP and I2NP
      message handling.
    * Fix some situations where we forward messages too eagerly.  For a
      request at the tunnel endpoint, if the tunnel is inbound and the target
      is remote, honor the message by tunnel routing the data rather than
      sending it directly to the requested location.
