Add "udp" for "listen_port" parameter, add stream resource example into README

[jurim76]

Please add "udp" option for "listen_port" parameter (need for nginx UDP load-balancer for example).
Also stream resource usage is not documented in README

stream {
  server {
    listen 514 udp;
  }
}

I think this should probably be accomplished with a new parameter, like listen_protocol vs. trying to extend listen_port.

It shouldn't be too hard, if I get a chance, I'll try to create a PR for this. As far as docs fixes, if you have time to write up a PR (or even draft the text or post a patch), it will definitely be reviewed.

Thank you! I've added an example patch for README.md file

Actually, I started looking at implementing this, and I think listen_options will do what you want with the module as-is.
In fact, your readme seems to suggest the same thing. Can you explain why that doesn't work?

I was thinking of a more general purpose example, but that works... I submitted #1021
I'm pretty sure listen_options is sufficient, so I'm going to close this for now -- reoopen or comment if you think there's a reason that won't work.
