Do not apply AST-based optimizations if 'from __future__ import annotations' is used in order to
prevent information lost in the final version of the annotations.
bpo-37127, bpo-39984:
* trip_signal() and Py_AddPendingCall() now get the current Python
thread state using PyGILState_GetThisThreadState() rather than
_PyRuntimeState_GetThreadState() to be able to get it even if the
GIL is released.
* _PyEval_SignalReceived() now expects tstate rather than ceval.
* Remove ceval parameter of _PyEval_AddPendingCall(): ceval is now
get from tstate parameter.
* _PyThreadState_DeleteCurrent() now takes tstate rather than
runtime.
* Add ensure_tstate_not_null() helper to pystate.c.
* Add _PyEval_ReleaseLock() function.
* _PyThreadState_DeleteCurrent() now calls
_PyEval_ReleaseLock(tstate) and frees PyThreadState memory after
this call, not before.
* PyGILState_Release(): rename "tcur" variable to "tstate".
Extension modules: m_traverse, m_clear and m_free functions of
PyModuleDef are no longer called if the module state was requested
but is not allocated yet. This is the case immediately after the
module is created and before the module is executed (Py_mod_exec
function). More precisely, these functions are not called if m_size is
greater than 0 and the module state (as returned by
PyModule_GetState()) is NULL.
Extension modules without module state (m_size <= 0) are not affected.

* bpo-26067: Do not fail test_shutil.chown when gid/uid cannot be resolved
There is no guarantee that the users primary uid or gid can be resolved
in the unix group/account databases. Skip the last part of the chown
test if we cannot resolve the gid or uid to a name.

When the pull is not used via the context manager or terminate() is called, there is a system in multiprocessing.util that handles finalization of all pools via an atexit handler (the Finalize) class. This class registers the _terminate_pool handler in the registry of finalizers of the module, and that registry is called on interpreter exit via _exit_function. The problem is that the "happy" path with the context manager or manual call to finalize() does some extra steps that _terminate_pool does not. The step that is not executed when the atexit() handler calls _terminate_pool is pinging the _change_notifier queue to unblock the maintenance threads.
This commit moves the notification to the _terminate_pool function so is called from both code paths.

Some inline functions use mixed declarations and code. These end up
visible in third-party code that includes Python.h, which might not be
using a C99 compiler. Fix by moving the declarations first, like in
the old days.
In math_2(), the first PyFloat_AsDouble() call should be checked
for failure before the second call.
