_Py_AS_GC and all APIs to get PyGC_Head from PyObject* are not only unstable, but also private.

I thought PyGC_Head must not be used directly from extensions, so we changed its layout.

Since Julien said "my code does not access PyGC_Head at all", I still think it was not real ABI breakage.

I suppose other serious bug (e.g. dungling pointer, missing refcount increment, etc) caused the segfault.
