load balancing trickery

After cleaning up the sources a bit and making
sure it compiles on current Linux distros, I uploaded
my old IPv4/IPv6 load balancer to my github.

I started this project in 2004, back in the days
at university. 10 years ago, it was the first load balancer available for IPv6 and in 2006 I finally presented the project at
some balancing conference in Silicon Valley.
(Even though you see some other names of my CS department
there, the whole code is written by me. In academics however
you form research groups and you are not going to rock
the world single-core.)

It works on IP level, so its suitable to balance
SSL/VPN/tor traffic etc too. For IPv4 it has integrated
failover/hotplug support for the backend nodes.
