Branch: pythonudf
Log Message:
Added experimental Python3 support.
Two new configure options allow you to select the python client and the
python-config to link to.
--with-pyversion=FILE specifies the python client (e.g. /usr/bin/python3 for
python3)
--with-pyconfig=FILE specifies the python-config (e.g. /usr/bin/python3-config
for python3)
Note that Python3 support is not complete, loading marshalled code objects is
disabled (Tests:pyapi08,pyapi14) and returning 'bytes' objects triggers an
assertion (Tests:pyapi09, pyapi21).
In the future, we might want to have separate languages for Python2 and Python3
(e.g. LANGUAGE PYTHON, LANGUAGE PYTHON3), just like Postgres.
