[Python-Dev] Omit Py_buffer struct from Stable ABI for Python 3.2?

Currently [1], the implementation and the documentation for PEP 3118's
Py_buffer struct don't line up (there's an extra field in the
implementation that the PEP doesn't mention).

Accordingly, Mark and I think it may be a good idea to leave this
structure (and possibly related APIs) out of the stable ABI for the
3.2 release. I don't *think* it needs changing, but I'm not 100%
certain until we finish working through the problem and realign the
implementation and documentation. Applications and extension modules
that use this interface would still work - they would just have to
wait until 3.3 before they could consider migrating to the stable ABI.
