PyEval_ReInitThreads removed since python 3.8

[wujunfeng1]

Describe what happened:
PyEval_ReInitThreads() uses C.PyEval_ReInitThreads, but this symbol has been removed since python3.8.

Describe what you expected:
Please revise the code to check whether symbol C.PyEval_ReInitThreads exists. If not, just skip using this symbol in PyEval_ReInitThreads().

Steps to reproduce the issue:
With python 3.8, get go-python3 package.

just in case that it helps, I've done this for Python 3.8 here for my own use. Some more has to be removed for Python 3.9.
