Add warnings to the strop module, for to those functions that really

*are* obsolete; three variables and the maketrans() function are not
(yet) obsolete.

Add a compensating warnings.filterwarnings() call to test_strop.py.

Add this to the NEWS.

+  that are still imported into string.py).

 - Cookie.py now sorts key+value pairs by key in output strings.
 
 - pprint.isrecursive(object) didn't correctly identify recursive objects.
