HTTP/3: traffic-based flood detection. With this patch, all traffic over HTTP/3 bidi and uni streams is counted in the h3c->total_bytes field, and payload traffic is counted in the h3c->payload_bytes field. As long as total traffic is many times larger than payload traffic, we consider this to be a flood. Request header traffic is counted as if all fields are literal. Response header traffic is counted as is.
