This change doesn't fix https://bugs.python.org/issue40826 but change how the error is reported:

$ ./python
Python 3.10.0a0 (heads/pyos_interrupt:50c03b6d5c, Jun  1 2020, 20:33:02) 
>>> import os; os.close(0)
>>> Fatal Python error: PyOS_InterruptOccurred: the function must be called with the GIL held, but the GIL is released (the current Python thread state is NULL)
Python runtime state: initialized

Current thread 0x00007fb5791d4740 (most recent call first):
<no Python frame>
Abandon (core dumped)

* bpo-40826: Add _Py_EnsureTstateNotNULL() macro (GH-20571)

Add _Py_EnsureTstateNotNULL(tstate) macro: call Py_FatalError() if
tstate is NULL, the error message contains the current function name.

(cherry picked from commit 3026cad)
