61b59517fc Act as the authority even though were not 
letsencrypt needs to talk to the authoritative name server, but
I have all dns traffic redirected to here so we get the SOA using the
same request (probably only works by accident) and then make a request
to the address listed in the SOA

internal/dhcp4: make persistent errors actally persistent (#62) 
Previously, a permanent error would not be persisted for future
invocations of ObtainOrRenew. In practice, the daemon immediately
exited, so this made no difference.

internal/dns: prevent upstreams from being lost during reordering (#63) 
If upstreams were reordered between start of an upstream request and its
conclusion, the move-to-front operation would likely incorrectly reorder
upstreams: duplicate one and remove another. Instead, we abandon the
move-to-front operation if that was about to happen.

dhcp4d: ensure that SetHostname operates on the correct lease (#64) 
Previously SetHostname could operate on an expired lease, or even on a
lease for a different hwaddr, if the lease for the correct hwaddr
expired and the same lease ID was given away to someone else.

That's though mostly a theoretical concern, given the actual usage of
SetHostname and the time scales involved.

876f8e320f netconfig: de-configure old DHCPv4 addresses from uplink0 
It is generally not a good idea to have multiple IP addresses on the same
interface unless managing their relative priorities via metrics etc.

During an outage, I noticed that with multiple IP addresses,
Linux was using the old obsolete one to send out packets,
which does not work with the ISP.

With this change,
we still hold on to IP addresses for as long as possible,
but no longer.

fixes issue #57

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.
