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.
