[#ERL-407]: Fix httpc misbehaviour based on RFC7230, section 3.3.3
If a message is received with both a Transfer-Encoding and a
Content-Length header field, it might indicate an attempt to
perform request smuggling or response splitting and must be
handled as an error in default mode (not relaxed mode).
