* preserve DNS cache after adblock processing,
- 'unbound' and 'named' support this (please check readme)
- 'dnsmasq' now uses the 'servers-file' directive
to minimize the reload disruption,
even though the dns cache will be cleared after SIGHUP
- 'kresd' dns cache is persistent by upstream default, anyway
Turris Omnia devices need a small upstream software change
which is not accepted/implemented yet
