bpo-37206: Unrepresentable default values no longer represented as None. (GH-13933)

Browse source 
In ArgumentClinic, value "NULL" should now be used only for unrepresentable default values
(like in the optional third parameter of getattr). "None" should be used if None is accepted
as argument and passing None has the same effect as not passing the argument at all.
