avoid "Turkish four i problem"

    - Restore i2pbote (ticket #516)
    - Remove r31453 (cert expiring, host soon to be shut down permanently)

     and '220f8941ffde39c665c1213cbc27037defb3527f'

list.

    - More optimizations in recvEncrypted()
    - More efficient XOR
    - Reduce bandwidth stat update frequency
    - Check for repeated zero-length reads

Tanuki's script has a broken check for 
OSX versions older than Leopard that sets
the CPU bitness to 32 for < 10.5. Since the
doesn't even work on Tiger (or older) (and
our binary is quad-FAT), this check is not 
neeeded.

    - Ensure failsafe pumper code gets run on schedule
    - Don't copy the read buffers
    - Adjust minimum read buffers based on memory
    - New i2np.ntcp.useDirectBuffer option (default false)
    - Mark peer unreachable when read failure is during establishment
    - Change some Reader Lists to Sets to avoid linear search
    - Log tweaks, debugging, new loop stats

    - First cut at improving EventPumper performance (ticket #551)
    - Establishment timeout cleanup/concurrent
    - Remove some logging and stats
    - Switch some Queues from LBQ to CLQ
    - Static ByteBuffer cache

  * NTCPConnection: Concurrent PrepBufs
  * OutNetMessage: Remove some fields and methods used only in NTCP debugging

    lots of I2P users

    - Less magic and fix img sizes, for speed and less artifacts while rendering
    - CSS tweaks

other DVCSes that I2P may be managed in aren't official.
