* Check for masked packages in the --resume merge list and bail

  out in that case (bug #199408).

* In depgraph.loadResumeCommand(), create a dependency graph from
  the resume list. This ensures that the merge list has it's
  dependencies satisfied. It also enables --tree display together
  with --resume.
