doc/go1.7.html: net/http RFC 2616 conformation + timeoutHandler on empty body
- Mention RFC 2616 conformation in which the server now only sends one
"Transfer-Encoding" header when "chunked" is explicitly set.
- Mention that a timeout handler now sends a 200 status code on
encountering an empty response body instead of sending back 0.
