Modified http_parser to handle ICY uris.

Browse source 
ICY URIs e.g `http://uk1.internet-radio.com/proxy/vombat?mp=/;` need to
be handled differently.

For basic use case, these URIs are similar to HTTP with exception that they reply with `ICY 200` etc in place of `HTTP/1.1 200`.

In http_parser, we now also parse ICY URIs to be able to handle these similar to HTTP.
