Debian initscript tweak.
Dnsmasq's startup script seems to assume users always want to use
dnsmasq as local DNS resolver, and tells resolvconf to put
"nameserver 127.0.0.1" in /etc/resolv.conf
The problem with this is that if users just want to use dnsmasq
as DHCP server, and put port=0 in /etc/dnsmasq.conf to disable
the DNS functionality, they end up with broken name resolving.
Put a basic check in the startup script that skips resolvconf
configuration if a line starting with port=0 is in /etc/dnsmasq.conf
This doesn't cover all cases (e.g. configuration could also be in
different file in /etc/dnsmasq.d), but is better than current
situation.
