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.

5ad6d5cbc4 feat(kernel/converter): add eta-expansion to converter, this is important when terms contains metavariables 
For example, consider the unification constrains

    fun (x : A), f (?m x)  =?=  f

Eta-reduction is not applicable since (?m x) is not a variable.
However, if we eta-expand the left-hand-side, we get

   fun (x : A), f (?m x)  =?=  fun (x : A), f x

which is reduced to

      (?m x) =?= x
