How do I get the default Network Manager plus dnsmasq-base setup back again?

/etc/default/dnsmasq, /etc/dnsmasq.conf and /etc/init.d/dnsmasq are all
gone.

/etc/dnsmasq.d/ still exists but has a single file "network-manager" in
it which I think is as it should be for the default setup.  It's like
that on the similar system I have where the dnsmasq run by network
manager is working OK.

Yes, I could do that, but I'd really like to get back to the default
setup.  I keep my system as standard as I possibly can.

It all actually works OK as it is of course because the DNS is set up
correctly in /etc/resolv.conf by Network Manager (pointing at my new DNS
server on the LAN).
