New issue 2447: cpyext: _PyObject_GetDictPtr is unimplemented

Wenzel Jakob:

The implementation _PyObject_GetDictPtr currently looks like a placeholder that always returns NULL.

@cpython_api([PyObject], PyObjectP, error=CANNOT_FAIL)
def _PyObject_GetDictPtr(space, op):
    return lltype.nullptr(PyObjectP.TO)

This breaks one of the remaining testcases in pybind11 covering types with a modifiable dictionary.

It would be great if this could be modified to return the pointer at tp_dictoffset for types who have this field set up before PyType_Ready.
