e206fcc1af perf(kernel/type_checker): reduce the overhead of creating delayed_justification objects, a huge number of them is created when type checking applications 
We reduce the cost by avoiding the allocation of std::functional objects, and the unnecessary increment/decrement of reference counters.

The name was misleading since not every declaration is a definition.

7b15e558a2 refactor(kernel/converter): implement eta in whnf instead of is_def_eq. 
Without cumulativity, we do not have problems with Eta at whnf anymore.
When we had cumulativity, we could not not simply reduce
     (fun x : A, f x) ==> f
This step is correct only if domain(f) was definitionally equal to f.
Here is a problematic example for systems with cumulativity
Given, f : Type.{2} -> Bool
     (fun x : Type.{1}, f x)
