- New auto hints for transparency/opacity control, not bound to
syntax yet. Doesn't change the auto/eauto behavior either.
- Typeclass resolution now considers everything transparent by
default and does it consistently for "open" and closed terms.
- Correctly declare singleton classes definition as opaque for proof
search.
- Add a few initial declarations to make iff, id, compose... opaque
- Add definition of dependent signatures for dependent function types
and remove corresponding exception code in class_tactics. The
instance requires higher-order unification and is not really usable yet.
