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.

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.
