It is no longer possible to build the _ctypes extension module
without wchar_t type: remove CTYPES_UNICODE macro. Anyway, the
wchar_t type is required to build Python.
* Call _PyTime_Init() and _PyWarnings_InitState() earlier during the
Python initialization.
* Inline _PyImportHooks_Init() into _PySys_InitCore().
* The _warnings initialization function no longer call
_PyWarnings_InitState() to prevent resetting filters_version to 0.
* _PyWarnings_InitState() now returns an int and no longer clear the
state in case of error (it's done anyway at Python exit).
* Rework init_importlib(), fix refleaks on errors.
Fix reference leaks in the error path of the initialization function
the _ctypes extension module: call Py_DECREF(mod) on error.
Change PyCFuncPtr_Type name from _ctypes.PyCFuncPtr to
_ctypes.CFuncPtr to be consistent with the name exposed in the
_ctypes namespace (_ctypes.CFuncPtr).
Split PyInit__ctypes() function into sub-functions and add macros for
readability.
bpo-1635741, bpo-40170: When called on a static type with NULL
tp_base, PyType_Ready() no longer increments the reference count of
the PyBaseObject_Type ("object). PyTypeObject.tp_base is a strong
reference on a heap type, but it is borrowed reference on a static
type.
Fix 99 reference leaks at Python exit (showrefcount 18623 => 18524).
Added a note in the `subprocess` docs that recommend using `shlex.quote` without mentioning that this is only applicable to Unix.
Also added a warning straight into the `shlex` docs since it only says "for simple syntaxes resembling that of the Unix shell" and says using `quote` plugs the security hole without mentioning this important caveat.
# Improve asyncio.wait function
The original code creates the futures set two times.
We can create this set before, avoiding the second creation.
This new behaviour [breaks the aiokafka library](https://github.com/aio-libs/aiokafka/pull/672), because it gives an iterator to that function, so the second iteration become empty.

Fix _PyConfig_Read() if compute_path_config=0: use values set by
Py_SetPath(), Py_SetPythonHome() and Py_SetProgramName(). Add
compute_path_config parameter to _PyConfig_InitPathConfig().
The following functions now return NULL if called before
Py_Initialize():
* Py_GetExecPrefix()
* Py_GetPath()
* Py_GetPrefix()
* Py_GetProgramFullPath()
* Py_GetProgramName()
* Py_GetPythonHome()
These functions no longer automatically computes the Python Path
Configuration. Moreover, Py_SetPath() no longer computes
program_full_path.
The onerror is supposed to be called with failed function, but in this case lstat is wrongly used instead of open.
Not sure if this needs bug or not...

The path configuration is now computed in the "main" initialization.
The core initialization no longer computes it.
* Add _PyConfig_Read() function to read the configuration without
computing the path configuration.
* pyinit_core() no longer computes the path configuration: it is now
computed by init_interp_main().
* The path configuration output members of PyConfig are now optional:
* executable
* base_executable
* prefix
* base_prefix
* exec_prefix
* base_exec_prefix
* _PySys_UpdateConfig() now skips NULL strings in PyConfig.
* _testembed: Rename test_set_config() to test_init_set_config() for
consistency with other tests.
Adds support to Tools/i18n/pygettext.py for gettext calls in f-strings. This process is done by parsing the f-strings, processing each value, and flagging the ones which contain a gettext call.

* Add support for macOS 11 and Apple Silicon (aka arm64)
As a side effect of this work use the system copy of libffi on macOS, and remove the vendored copy
* Support building on recent versions of macOS while deploying to older versions
This allows building installers on macOS 11 while still supporting macOS 10.9.
* The AST optimiser wasn't descending into named expressions, so
any constant subexpressions weren't being folded at compile time
* Remove "default:" clauses inside the AST optimiser code to reduce the
risk of similar bugs passing unnoticed in future compiler changes
The format_exception(), format_exception_only(), and
print_exception() functions can now take an exception object as a positional-only argument.

The PyConfig_Read() function now only parses PyConfig.argv arguments
once: PyConfig.parse_argv is set to 2 after arguments are parsed.
Since Python arguments are strippped from PyConfig.argv, parsing
arguments twice would parse the application options as Python
options.
* Rework the PyConfig documentation.
* Fix _testinternalcapi.set_config() error handling.
* SetConfigTests no longer needs parse_argv=0 when restoring the old
configuration.
Currently, a Mock object which is not unsafe will raise an
AttributeError if an attribute with the prefix assert or assret is
accessed on it. This protects against misspellings of real assert
method calls, which lead to tests passing silently even if the tested
code does not satisfy the intended assertion.
Recently a check was done in a large code base (Google) and three
more frequent ways of misspelling assert were found causing harm:
asert, aseert, assrt. These are now added to the existing check.
* Inline _PyInterpreterState_SetConfig(): replace it with
_PyConfig_Copy().
* Add _PyErr_SetFromPyStatus()
* Add _PyInterpreterState_GetConfigCopy()
* Add a new _PyInterpreterState_SetConfig() function.
* Add an unit which gets, modifies, and sets the config.
Otherwise, when running the testsuite, test_peg_generator tries to compile C
code using the optimized flags and fails because it cannot find the profile
data.
