Refactor Debian repo to use two branches (dist-stable and dist-unstable) so that we can update "unstable" and "testing" separately without changing commits for "stable" and friends

The change in "stable" here is just a rebase to no longer include "unstable" and "testing" -- no actual changes (and so no rebuilds necessary there).

The change in "unstable", "testing", "sid", and "stretch" is the money shot -- updated for the recent CVE (and other unrelated updates).
