(ticket #103)

http://forum.i2p/viewtopic.php?t=5061

  stopped announces go out and reopen it
- Logging tweaks

- Make sure lastRequest is null when it should be
- Logging tweaks

      - Priority mapping bugfix
      - Close files as we go when creating/checking
        so we don't run out of file descriptors

      - Don't stay interested if we run out of pieces
        to request (thanks sponge)
      - Enhance debug mode to show requests

                Apache Harmony's Pack200, add unzip to main()

    * ampersand escaping (lots more to do)

      to reduce LogManager records

      Use context random for shuffle; other cleanups

      speed announces in i2psnark

              and '4ef1d99f924ee431587d6f85241540e031fecbc1'
        to branch 'i2p.i2p'


Explicit merge from test4.
1.6 JDK now required to build.
1.5 JRE still OK to run I2P.

    * configlogging.jsp:
      - Add easy way to add an override
      - Make file size specifier more flexible
    * Console:
      - Sort RouterAddress options on netdb.jsp and peers.jsp
      - Remove unused web-*.xml file from war
    * Crypto:
      - Convert all ArrayList caching to LBQs in YKGenerator,
        HMACGenerator, and AESKeyCache.
      - Change DSAEngine params from Hash to new SHA1Hash, since
        these were really 20 byte hashes, not 32 byte Hashes.
      - Add stats to track YKGenerator caching success
      - Fix YKGenerator precalculation to be much more useful by
        increasing the cache size and dramatically shortening the delay
      - Option cleanups
      - YKGenerator cleanups
      - Mark HMAC256Generator unused
    * EepGet: Reset length variable on redirect
    * Files: Change permissions to 600/700 for all written files/directories.
      Now requires Java 1.6 to build, but only 1.5+ to run.
      (requires 1.6 to set permissiomns)
    * GeoIP: Fix locking bug causing lookups to stop
    * Hash: Throw IAE if data length is not 32 bytes,
      now that DSAEngine abuse is gone
    * HTTPResponseOutputStream:
      - More caching
      - Stats cleanup
      - Max header length check
      - Catch OOM
      - Initializer cleanup
      - Javadoc
    * I2CP:
      - Add new option i2cp.messageReliability=none, which prevents the
        router from sending MessageStatusMessages back in reply to an
        outbound SendMessageMessage. Since the streaming lib always ignored
        the MSMs anyway, make it the default for streaming.
        This will reduce the I2CP traffic significantly.
        MSM handling now avoided, but it is still fairly broken, see
        comments in I2PSessionImpl2.
      - Cleanups to replace method calls with fields
      - More cleanups, javadoc, rate reduction
    * i2psnark:
      - Compact response format
      - Add link to finished torrent in message box
      - Don't let one bad torrent prevent others from
        starting or stopping
      - Sort peers by completion %
      - Add some missing mime types to web.xml
      - shouldLog() cleanup
    * i2ptunnel:
      - Now that streaming flush() is fixed, use it in IRCClient, and
        for initial data in I2PTunnel runner, to avoid the 250 ms
        passive flush delay
      - Add hostname DSA signature field, to be used for addkey forms.
        Experimental, may be commented out later.
      - More header blocking (thanks telecomix!)
      - Remove unused web-*.xml file from war
    * Installer: Add startup hint for non-x86
    * Javadoc updates all over the place
    * LogConsoleBuffer: Java 5
    * Naming:
      - Increase cache size and expiration time
      - Add clearCache() method
      - Don't use EepGet or Exec for b32
      - Javadoc updates
    * NetDB:
      - Expire unreachable routers quickly, even if they don't have introducers,
        so we don't have old data on routers that ran out of introducers.
      - Fix rare NPEs at shutdown
    * NTCP:
      - Workaround for a rare 100% CPU bug in EventPumper
      - Cleanups
    * Streaming:
      - Make flush() block less, by waiting only for "accept" into the
        streaming queue rather than "completion" (i.e. ACK from the far end).
        This prevents complete stalls when flushing, and should help performance
        of apps that use flush(), like i2psnark (and SAM?).
        close() still does a flush that waits for completion, as i2ptunnel
        doesn't like a fast return from close().
      - cleanups
    * SusiDNS:
      - Remove unused web-*.xml file from war
    * TransportManager: Convert _transports from a List to a CHM
      to prevent a rare concurrent exception
    * Tunnels:
      - Don't use peers < 0.7.9 for tunnels due to the old
        message corruption bugs
      - Javadoc
      - Cleanups
    * UDP:
      - Beginnings of destroy message support
      - Try to avoid running out of introducers by relaxing selection criteria
        and increasing minimum number of potential introducers
      - Avoid rare AIOOBE
      - PacketBuilder refactor
      - Make most classes package private
      - Comments
      - Logging cleanup
      - Comment out a main()

      - Make flush() block less, by waiting only for "accept" into the
        streaming queue rather than "completion" (i.e. ACK from the far end).
        This prevents complete window stalls when flushing, and should help performance
        of apps that use flush(), like i2psnark (and SAM?).
        close() still does a flush that waits for completion, as i2ptunnel
        doesn't like a fast return from close().
      - flush/close javadocs and comments
    * i2ptunnel:
      - Now that streaming flush() is fixed, use it in IRCClient, and
        for initial data in I2PTunnelRunner, to avoid the 250 ms
        passive flush delay

      - Add easy way to add an override
      - Make file size specifier more flexible
