Subject: Moving the argument of CProdN/CLambdaN from binder_expr to
 local_binder_expr.

The motivations are:

- To reflect the concrete syntax more closely.
- To factorize the different places where "contexts" are internalized:
  before this patch, there is a different treatment of `Definition f
  '(x,y) := x+y` and `Definition f := fun '(x,y) => x+y`, and a hack
  to interpret `Definition f `pat := c : t`. With the patch, the fix
  to avoid seeing a variable named `pat` works for both `fun 'x =>
  ...` and `Definition f 'x := ...`.

The drawbacks are:

- Counterpart to reflecting the concrete syntax more closerly, there
  are more redundancies in the syntax. For instance, the case `CLetIn
  (na,b,t,c)` can appears also in the form `CProdN (CLocalDef
  (na,b,t)::rest,d)` and `CLambdaN (CLocalDef (na,b,t)::rest,d)`.
- Changes in the API, hence adaptation of plugins referring to `constr_expr` needed.
