Update README.Debian with notes about root-equivalence
Update d/control to recommend either cgroupfs-mount OR cgroup-lite (which is an Ubuntu-only package similar to cgroupfs-mount)
Add new upstream gitcommit
Update d/watch to support both +dfsg and ~dfsg properly
Add new d/changelog entry, taking the bump opportunity to also swap from +dfsg1 to ~dfsg1 like I'm told we should've been using all along! :)
