This commit should be easy to cherry-pick and backport to latest
release. However, there is a potential risk that user code
implementing __getbuffer__ in extension classes do not make the check
"if info == NULL: return", and then you get a SEGFAULT. AFAIK, all
this business with Py_buffer pointer being NULL was added because of
some obscure bug in Python==3.0.x, but I would expect people out there
to be using Python >= 3.1.x, so not a big deal.
