* HEAD request which may contain 'Content-Length' or 'Transfer-Encoding:

* Returning `2` from on_headers_complete will tell parser that it should not
* expect neither a body nor any futher responses on this connection. This is
* useful for handling responses to a CONNECT request which may not contain
* `Upgrade` or `Connection: upgrade` headers.
*
* http_data_cb does not return data chunks. It will be called arbitrarily
* many times for each string. E.G. you might get 10 callbacks for "on_url"
* each providing just a few characters more data.
