dnsmasq: add listen_address parameter

Browse source 
This patch adds a parser for the uci representation of
dnsmasq's "-a | --listen-address" option.

In summary, this option forces dnsmasq to listen on the
given IP address(es). Both interface and listen-address
options may be given, in which case the set of both
interfaces and addresses is used.

Note that if no interface option is given, but listen_address is,
dnsmasq will not automatically listen on the loopback interface.
To achieve this, the loopback IP addresses, 127.0.0.1 and/or ::1
must be explicitly added.

This option is useful for ujailed dnsmasq instances, that would
otherwise fail to work properly, because listening to the
"This host on this network" address (aka 0.0.0.0 see rfc1700 page 4)
may not be allowed.
