d47d326cef fix(library/unifier): bug in mk_imitiation_arg 
Remove bogus constraint
     cs.push_back(mk_eq_cnstr(mk_app(maux_type, locals), type, j, relax));
This constraint is incorrect because 'type' may contain local constants that are not in 'locals'.

We just rely on
   cs.push_back(mk_eq_cnstr(mk_app(maux, margs), arg, j, relax));
When maux is assigned, the system will inforce that its type (which is based on maux_type) must be type correct

faee08591f fix(*): make sure elaborator and type_checker use the same "rules" for treating opaque definitions 
This is a big change because we have to store in constraints whether we can use the "relaxed" rules or not.
The "relaxed" case says that when type checking the value of an opaque definition we can treat other opaque definitions in the same module as transparent.

a1601e7a5f feat(library/tactic/apply_tactic): add option for 'refreshing' universe metavariables in the 'apply' tactic 
The new test ../../tests/lean/run/tactic27.lean demonstrates why we need this feature. The tactic 'apply @refl' is actually 'apply @refl.{?l}'. It is used inside of a repeat tactical. Each iteration of the 'repeat' may need to use a different value for ?l. Before this commit, there was not way to say we want a fresh ?l each iteration.
