[Python-3000] Draft PEP: Dropping PyObject_HEAD

[Daniel Stutzbach]

To facilitate migration, I have a few suggestions:

- add the new access macros to 2.6 (defined appropriately)
- in 3.0, instead of removing PyObject_HEAD and company, redefine them
appropriately, .e.g, #define PyObject_HEAD PyObject obtype;
