I think now the memory perhaps should be allocated with PyMem_New and
deallocated with PyMem_Free.

Additionally, the return should perhaps indicate success or failure,
and a new argument should be passed in order to know if a copy was
made, something like

int PyObject_GetContiguous(PyObject *obj,
                                           void **buf, Py_ssize_t
*len, int *copy,
                                           char layout)
