Fix interpreter crashes.

Still doesn't look right.

Remove raw ob_refcnt references in typeobject.c

Fix build.

Interpreter now segfaults. Whoop.

5. By Phil Connell on 2013-04-19

Fix sense of the Py_BOX macros (they're all Py_UNBOXED now).

Also a minor refactor in longobject: _PyLong_AsLong_RETURN_UNBOXED
shortcircuits the PyLong_AsLong functions.

Fix build errors in longobject.c

Things that need to be sorted out:
    - Errors (more Py_TYPE_UPDATE uses needed)
    - Bunch of warnings that need cleaning up
    - Ugly casts all over the place:
        - is uintptr_t the right type for 'unboxed' pointers? (probably)
        - why all the casts between PyLongObject and PyObject?

Add distinct macros to change an refcounts and types

Previously, Py_REFCNT and PY_TYPE were used both as lvalues and rvalues. To
cope with unboxed types, they need to include a condition (or a
bitwise/arithmetic expression), which can't be used as an lvalue.

So, Py_REFCNF_UPDATE and Py_TYPE_UPDATE are added to be used where the old
macros would have been used as lvalues.
