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.

bd8fc63b0e dns: implement per-DHCP-lease dyndns 
The HTTP API is easy to use from the command line or from Go:

% curl --data "host=sub&ip=192.168.33.44" -4 http://router7:8053/dyndns
ok
% host sub.$(hostname)
sub.midna has address 192.168.33.44

This can be used in combination with https://github.com/gokrazy/gdns

ac883da6a5 dns_test: xps → testtarget 
This fixes running the tests on xps, where the entry derived from os.Hostname
would clash with the xps entries the testcase tries to install.
