Jens Rehsack 2497cf2960 dnsmasq: steal resolvconf support from Ubuntu
Add support for resolvconf integration as done in Ubuntu. This implies
updates of start-scripts, resolvconf plugin (on nameserver update ...),
populate-volatiles control file for saved nameserver list.

RESOLV_CONF:

If the resolvconf package is installed then use the resolv conf file

that it provides as the default. Otherwise use /etc/resolv.conf as

the default.

If IGNORE_RESOLVCONF is set in /etc/default/dnsmasq or an explicit

filename is set there then this inhibits the use of the resolvconf-provided

information.

Note that if the resolvconf package is installed it is not possible to

override it just by configuration in /etc/dnsmasq.conf, it is necessary

to set IGNORE_RESOLVCONF=yes in /etc/default/dnsmasq.
