   - Limit PacketHandler threads to 1 (ticket #660)
   - Limit queue sizes between UDPReceiver and PacketHandler,
     and between PacketHandler and MessageReceiver, to prevent OOMs
     and/or excessive queue delays
   - Increase UDPPacket cache size based on max mem
   - Remove more stats

 * I2PSessionImpl: One more volatile (ticket #659)

     and '925b1411e60b0e76e2421becd84d6c63832b69bb'

At the same time I'm making more Debian-specific changes, such as
 - not checking for Gentoo (this is obviously never going to be true :P)
 - not mentioning IzPack replacing variables (also not applicable)
 - inform about dpkg-reconfigure i2p in the event someone tries to remove or
   install an initscript with "i2prouter install|remove|uninstall"
 - remove the manual wrapper instructions

This will solve the issue of I2P_CONFIG_DIR being set incorrectly if another
user runs i2prouter once, such as when installing the initscript.

- Protect against null DHT races
- Add message about restarting tunnel when DHT config changes
- Add DHT size to table totals
