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.
