Summary: PEP 3123 implementation
Initial Comment:
This patch implements the changes need for PEP 3123, in Py3k. Rather than
checking this into the 3k branch, a backport of those bulk of the patch to 2.6
should be made, omitting the actual changes to PyObject_HEAD

I like this patch would like it to be applied to 2.6. However, I'm
concerned about extension modules maintaining compatibility for 2.5 and
3.0. What would that look like (ie, an extension module that can compile
with both versions)? How would the modules need to be changed to support
both versions? For Py_{Type,Refcnt,Size}, it looks pretty straightforward
to define the macros in 2.x and things should work fine. But I'm not sure
about the HEAD_INIT macros.
Martin, did you try disabling the -fno-strict-aliasing with this patch to
see if there were any warnings?
