Rework the dependencies between excuses. Dependencies are specified based on packages (source or binary). Based on these packages, dependencies on other excuses (that have these packages) are calculated. As with package dependencies, dependencies between excuses can contain alternatives. Each alternative can satisfy the dependency, so the excuse only becomes invalid if all of the alternatives of a specific dependency are invalidated. Tracking of the alternatives and their validity is moved to separate objects.
