Vincent Ambo 5d9d84f4cf refactor: Pass the depot as an argument named 'depot'
This change, which I've been meaning to do for a while, renames the
attributes passed by readTree to things in the tree so that:

* the depot root is now 'depot'
* depot.third_party is additionally passed as 'pkgs' (for
  compatibility with exported subtrees)
