Summary: Reference counting bugs

Initial Comment:
Various refcounting bugs:

1. Objects/abstract.c: PyObject_Call():
missing Py_DECREF() on the object returned by 
PyObject_Repr(func). Moreover this function's return 
value is not tested for NULL, which might crash the 
interpreter.

2. Objects/funcobjects.c: function_call():
the Py_DECREF(arg) after PyErr_NoMemory() should be 
removed

3. Python/ceval.c: unpack_iterable():
in the path through the error "too many values to 
unpack", a Py_DECREF(w) is missing

4. Python/ceval.c: apply_slice():
the slice object returned by PySlice_New() is never 
Py_DECREF'ed.

5. Python/ceval.c: assign_slice():
the slice object returned by PySlice_New() is never 
Py_DECREF'ed.
