Subject: [PATCH] Always bind Cython functions in py3

Rebased for cython 0.29.x, and made conditional to Python 3.  This
does not solve the original staticmethod problem in Python 2 but it does
resolve classmethod problems in Python 3.9.  Therefore, it unbreaks
other packages on Python 3.9, improves overall state for Python 3
and does not introduce regressions in Python 2.
