Added a new debug method sys.gettotalrefcount(), which returns the total number of references on all Python objects. This is only enabled when Py_TRACE_REFS is defined (which includes default debug builds under Windows).
Also removed a redundant cast from sys.getrefcount(), as discussed on the patches list.
