[openbeos] We need netcat!

After struglling all week with my RTSP client I was able to debug and fix it in 
30 minutes with netcat. (Admitedly it was almost correct)

$> nc -l -p 3333 -x "Maximize-Reliability" -c "nc -o ~/dump localhost 8554"
setup a pass through server that would record the data sent

The setup's and play's "'RTSP/1.0\r\n" was missing "0\r\n"
The setup's and play's CSeq was followed by an NUL then garbage.
The setup's Transport field was followed by NUL
The paly's session was followed by NUL and garbage.
The play had no blank line to terminate the request.

Most of the problems were send sizes.

And live555's media server parsed and aprroved that grabage request. 

I was using Hobbit's netcat, public domain open source, on ubuntu.
