Brad Fitzpatrick e415991256 derp, derp/derphttp: remove one RTT from DERP setup ... * advertise server's DERP public key following its ServerHello * have client look for that DEPR public key in the response PeerCertificates * let client advertise it's going into a "fast start" mode if it finds it * modify server to support that fast start mode, just not sending the HTTP response header Cuts down another round trip, bringing the latency of being able to write our first DERP frame from SF to Bangalore from ~725ms (3 RTT) to ~481ms (2 RTT: TCP and TLS).
