* Resynchronise with Debian. Remaining Ubuntu changes: - debian/control: + Add versioned dependency on the dbus that satisfies our upstart job dependency. + Add udebs corresponding to libavahi-common3 and libavahi-core6, so that we can use them for Eucalyptus integration in the installer. - Add debian/avahi-daemon.upstart, debian/avahi-dnsconfd.upstart - debian/avahi-autoipd.{pre,post}inst: Adjust package versions for conffile migration for the version when Ubuntu did the DHCP4 migration. This needs to be kept until after the next LTS.
