[libmicrohttpd] tiny websocket above LMHD

[José Bollo]

I am proud to share with you a tiny implementation of websocket with
libmicrohttpd.

You can find it there:

I tried to give something small and useful (based on some previous work
I made).

It is not perfect so feedback are welcome. Especially I only work on
linux. People on Mac or BSD are welcome to submit issues or pull
requests. People of windows also of course.

Best regards
José Bollo
