[LispM] Chaosnet bridge

[Björn Victor]

Since playing with Daniel's Lambda emulator is so much fun, and I 
already had an ITS system running, I felt an urge to connect them. I 
wrote a bridge program for different Chaosnet link implementations: 
Chaosnet-over-Ethernet (which LambdaDelta, and real hardware, use), 
Chaosnet-over-UDP (which the klh10 PDP10 emulator running ITS uses), and 
Chaosnet-over-Unix-sockets (which the CADR emulator usim uses).

It can be used to interconnect these types of chaosnets and act as a 
bridge, sending routing packets and responding to the STATUS protocol. 
It should be useful also to connect users of LambdaDelta to eachother, 
or to users of usim - and of course ITS.

You can find it at https://github.com/bictorv/chaosnet-bridge - please 
let me know if you use it (or find bugs in it!), and if you want to 
connect to my Chaosnets!
