[pypy-dev] improved cpyext PyArg_ParseTuple s* and t# support

[exarkun at twistedmatrix.com]

Hello,

There's a pyarg-parsebuffer-new branch in the pypy bitbucket repository 
that improves PyArg_ParseTuple.  It doesn't completely implement either 
of these, but it adds enough for pyOpenSSL to mostly work.  Arbitrary 
new-style buffer support was too hard for me, so I skipped that.  Still, 
it would be nice to have this branch in 1.5 if possible, since I think 
with it along with my pyOpenSSL branch, pyOpenSSL becomes mostly 
functional on PyPy.

Can someone take a look and let me know if it's okay to merge to 
default?

Thanks,
Jean-Paul
