/* This does the basic initialization of Python. It can be called
completely concurrently from unrelated threads. It assumes
that we don't hold the GIL before (if it exists), and we don't
hold it afterwards.
What it really does is completely different in Python 2 and
Python 3.
Python 2
========
Initialize the GIL, without initializing the rest of Python,
by calling PyEval_InitThreads().
PyEval_InitThreads() must not be called concurrently at all.
So we use a global variable as a simple spin lock. This global
variable must be from 'libpythonX.Y.so', not from this
cffi-based extension module, because it must be shared from
different cffi-based extension modules. We choose
_PyParser_TokenNames[0] as a completely arbitrary pointer value
that is never written to. The default is to point to the
string "ENDMARKER". We change it temporarily to point to the
next character in that string. (Yes, I know it's REALLY
obscure.)
Python 3
========
In Python 3, PyEval_InitThreads() cannot be called before
Py_InitializeEx() any more. So this function calls
Py_InitializeEx() first. It uses the same obscure logic to
make sure we never call it concurrently.
Arguably, this is less good on the spinlock, because
Py_InitializeEx() takes much longer to run than
PyEval_InitThreads(). But I didn't find a way around it.
