- Combine getPeers and announce into a single method, as we must announce to
     the closest from the getPeers, not the closest from the kbuckets
   - Stop getPeers when nothing closer is found

   - Increase dest lookup and search timeouts
   - Increase max search depth
   - Loop tracker client faster when in magnet mode
   - Loop tracker client faster if DHT announce fails
   - Don't return an empty peers list if we only know about the requestor
   - volatiles, log tweaks
   - Major fixes of getPeers() to follow

     (unlikely as we don't show the "hide news" button for initial news)
     Also prevent string IOOBE

   - Thread news fetcher so it doesn't clog the scheduler

   - Make Destination and RouterIdentity keys and cert immutable
   - Add Destination cache

   (reduce ByteArray[] size where possible)

   - Require strict match of class name component
   - parseLimits() cleanup

   0::/8 - Includes IPv4 compatibility addresses ::xxxx:xxxx

   - Add torrent auto-stop support; enable for update file
   - Add tunnel auto-close when no torrents are running
   - Log/msg tweaks on add/create failures

   - Prevent multiple calls or reentrancy in disconnect() (ticket #1041)
   - Implement processing of close to skip TIME-WAIT, and
     wait for all packets to be acked (not just the CLOSE) before
     doing so, if possible (ticket #1042)
   - Don't call disconnect() or disconnectComplete() from I2PSocketFull.destroy()
     so retransmissions and acks can still happen (removes some close loops)
   - Don't call disconnect() until we have both sent and received a CLOSE (ticket #1040)
   - Don't reset the connection from CPH just because we sent a CLOSE
     and it was acked (ticket #1040)
   - Ack packets even if we sent a CLOSE  (ticket #1040)
   - Retransmit CLOSE if not acked (ticket #1040)
   - Send received packets to the MessageInputStream even if we haven't received a SYN
   - Don't call MessageInputStream.messageReceived() for ack-only packets, that was pointless
   - Don't send a RESET after timeout of an outbound connection
   - Work around bugs on other end by limiting retransmission of CLOSE packets
   - Make _isInbound final
   - More cleanups, javadocs, log tweaks

            if it has a send ID set, it must be for a recently closed connection

   - Cleanups
   - Remove setCloseReceivedOn(), unused outside Connection
   - OR the isFlagSet parameter instead of multiple calls
   - Remove acked packets from _outboundPackets inside synced iterator
   - Short-circuit _outboundPackets iterator if empty
   - Small optimization if not logging in ConnectionPacketHandler
   - Stub out processing of close ack (ticket #1042)

   so we only do things once. (Ticket #1041)

   we only do it once. (Ticket #1041)

   that are closed and in TIME-WAIT state. Also, break out of the
   counting loop as soon as we know the answer. (Ticket #1039)

   on /configclients (Ticket #1025)

   due to "constraints". Add constraint checks for java version,
   router version, configuration, and base permissions. (ticket #1024)
