[ubuntu/plucky-proposed] apt 2.9.28 (Accepted)

[Julian Andres Klode]

apt (2.9.28) unstable; urgency=medium

  [ Julian Andres Klode ]
  * modernize-sources: Avoid opening /dev/stdout for simulate
  * dpkg: Pass --admindir if a different one is specified; fixes issue
    where foreign architectures from the host were used when Dir is set.
  * Various updates to the '3.0' solver: Particularly it now has a clause
    database for reals rather than rediscovering clauses when backtracking.
    - refactor: Drop unused code, annotate [[nodiscard]] and const, simplify,
      extract functions, and particularly introduce the Clause class.
    - algorithm: Simplify work ordering. This may cause some changes in
      how dependencies are resolved.
    - algorithm: Replace PropagateInstall() with Discover() and then
      propagate based on the stored clauses. Clauses are discovered
      from package dependencies and persistent, i.e. they have no
      decision level associated. Discovery is incremental so far.
    - algorithm: Support comparing packages and versions, such that
      we can store both package and version variables in a clause.
    - algorithm: Use a package clause for optional roots. This allows
      deciding to keep an automatically installed package installed,
      without having to decide the version (and hence enqueue common
      dependencies first).
    - performance: Cache calls to policy.
    - performance: Cache all configuration calls
    - performance: Point to stored clauses, do not copy them
    - performance: Avoid std::vector for statically sized arrays. Due
      to adding libstdc++ assertions, vector range checks accounted
      for up to 20% of solver runtime.

  * completion: Add modernize-sources (Closes: #1094904)
  * edit-sources: don't force .list
