internal/core: merge adt with eval package

- eval.go is mostly unchanged, modulo a renaming
  from Evaluator to Unifier
- Evaluator is renamed to Unifier so that it can
  1) supplant the old Unifier interface
  2) doesn't conflict with the Evaluator type
     already in adt.
- Ultimately the new Unifier type can merge with
  OpContext.
- Shims are kept in the old eval package. These
  also add in the dependency on the debug package
  for more elaborate printing.
