HTTP/2: traffic-based flood detection. With this patch, all traffic over an HTTP/2 connection is counted in the h2c->total_bytes field, and payload traffic is counted in the h2c->payload_bytes field. As long as total traffic is many times larger than payload traffic, we consider this to be a flood.
