Michael Stapelberg 53c495091e quirk: enforce minimum lease time of 1 hour for Nintendo devices 
The Nintendo Switch has been observed to hold on to IP addresses even after
their expiration. My guess is that this is an oversight: likely the device
enters power saving mode with a configured IP address and just sleeps through
the expiration time.

As the device seems to wake up once every hour, we enforce a minimum lease time
of 1 hour, but only for affected devices. The rest of the network gets short
lease times.

Michael Stapelberg 66942bd4f7 dns: steer traffic toward the most response upstream 
There is not much of a difference between IPv4 and IPv6 on my fiber7 link, but
in other networks, there might well be.

For my connection, this commit results in hitting different upstreams all the
time because the list isn’t stable. But, this is the opposite of a problem: we
are spreading the DNS query load over all configured IPs, as good netizen do.
