- 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
