Fix invalid function signatures for PySequenceMethods callbacks

Browse Source 
Function casts hid casting between potentially incompatible type
signatures (using int instead of Py_ssize_t). As it happens this seems
not to have caused any bugs on supported platforms so this change is
mainly for correctness and to avoid problems in the future.
