It appears standard that moving the text insert cursor away from a selection clears the
selection. Clearing prevents accidental deletion of a possibly off-screen bit of text.
The update is for Ln and Col on the status bar.
* exit_thread_if_finalizing() does now access directly _PyRuntime
variable, rather than using tstate->interp->runtime since tstate
can be a dangling pointer after Py_Finalize() has been called.
* exit_thread_if_finalizing() is now called *before* calling
take_gil(). _PyRuntime.finalizing is an atomic variable,
we don't need to hold the GIL to access it.
* Add ensure_tstate_not_null() function to check that tstate is not
NULL at runtime. Check tstate earlier. take_gil() does not longer
check if tstate is NULL.
Cleanup:
* PyEval_RestoreThread() no longer saves/restores errno: it's already
done inside take_gil().
* PyEval_AcquireLock(), PyEval_AcquireThread(),
PyEval_RestoreThread() and _PyEval_EvalFrameDefault() now check if
tstate is valid with the new is_tstate_valid() function which uses
_PyMem_IsPtrFreed().
We make `|=` raise TypeError, since it would be surprising if `C.__dict__ |= {'x': 0}` silently did nothing, while `C.__dict__.update({'x': 0})` is an error.
The Py_FatalError() function is replaced with a macro which logs
automatically the name of the current function, unless the
Py_LIMITED_API macro is defined.
Changes:
* Add _Py_FatalErrorFunc() function.
* Remove the function name from the message of Py_FatalError() calls
which included the function name.
* Update tests.
Convert _PyRuntimeState.finalizing field to an atomic variable:
* Rename it to _finalizing
* Change its type to _Py_atomic_address
* Add _PyRuntimeState_GetFinalizing() and _PyRuntimeState_SetFinalizing()
functions
* Remove _Py_CURRENTLY_FINALIZING() function: replace it with testing
directly _PyRuntimeState_GetFinalizing() value
Convert _PyRuntimeState_GetThreadState() to static inline function.
set_herror builds a string by calling hstrerror but downcasts its return value to char *. It should be const char *.

test_subprocess.test_user() now skips the test on an user name if the
user name doesn't exist. For example, skip the test if the user
"nobody" doesn't exist on Linux.
`list(sys.modules.items())` was apparently not immune to "dictionary
changed size during iteration" errors.
Tested internally using an integration test that has run into this a couple of times in the past two years. With this patch applied, the test is no longer flaky.
The AST "Suite" node is no longer used and it can be removed from the ASDL definition and related structures (compiler, visitors, ...).

Reimplement distutils.spawn.spawn() function with the subprocess
module.
setup.py now uses a basic implementation of the subprocess module if
the subprocess module is not available: before required C extension
modules are built.
Add a section in What's New In Python 3.9 to strongly advice to check
for DeprecationWarning in your Python projects.
