BUG/MEDIUM: http: Fix tunnel mode when the CONNECT method is used
When a 2xx response to a CONNECT request is returned, the connection must be
switched in tunnel mode immediatly after the headers, and Transfer-Encoding and
Content-Length headers must be ignored. So from the HTTP parser point of view,
there is no body.
The bug comes from the fact the flag HTTP_MSGF_XFER_LEN was not set on the
response (This flag means that the body size can be determined. In our case, it
can, it is 0). So, during data forwarding, the connection was never switched in
tunnel mode and we were blocked in a state where we were waiting that the
server closes the connection to ends the response.
Setting the flag HTTP_MSGF_XFER_LEN on the response fixed the bug.
The code of http_wait_for_response has been slightly updated to be more
readable.
