* Change the abstract syntax of slices. It used to be that ids were used as

  keys to reference slice elements, e.g.,

    Slice(["1ef7..."], [("/nix/store/1ef7...-foo", "1ef7", ["8c99..."]), ...])

  This was wrong, since ids represent contents, not locations.  Therefore we
  now have:

    Slice(["/nix/store/1ef7..."], [("/nix/store/1ef7...-foo", "1ef7", ["/nix/store/8c99-..."]), ...])

* Fix a bug in the computation of slice closures that could cause slice
  elements to be duplicated.
