* Merge from Debian unstable (LP: #1219752). Remaining changes: - debian/control: Demote winbind from Recommends to Suggests. This avoids winbind being pulled onto the CD images when it's not required. - debian/patches/stat_systemd-ask-password.patch: also check for /bin/systemd-ask-password before trying to use systemd's tools. * Dropped undocumented quilt dependancies wrt old debian format transition in debian/control and debian/rules, as those are not necessary anymore.
