   - Close connection immediately if bad protocol,
     this makes blacklist work better too

- Disable KRPC
- Shorten tracker string

- Fix changing 'use open trackers' config setting (old bug)
- More TrackerClient fixes for no primary announce
- More BEValue.toString() improvements for debugging

- Better BEValue.toString()

(most of the following got missed in the last checkin)
- Fix about 9 NPEs
- Fix numwant in magnet mode
- Send metadata size in extension handshake
- Open trackers are primary if we don't have primary trackers
- Add missing break in port message handling
- Increase max msg size to account for metadata msg
- Remember magnets across restarts
- Drop peers w/o extensions if we need metainfo
- Fix DATA messages
- Fix tracker transition to non-magnet
- Fix infohash for non-magnet
- Fix up peer transition to non-magnet
- More logging

- Announce peers to local tracker
- Ping node on port reception
- More info on directory pages
- Cleanups

and lots of prep for lack of metainfo and storage.

  stopped announces go out and reopen it
- Logging tweaks

      Use context random for shuffle; other cleanups

  - Rework PeerID class so it depends only on peer desthash, since
    peer ID is not available with compact format. Implement deferred
    lookup of destination.
  - Implement compact tracker requests and response handling
    (may not be the final format)
  - Fix Peer hashCode()
  - Java 5
