bpo-42296: On Windows, fix CTRL+C regression (GH-23257)
On Windows, fix a regression in signal handling which prevented to
interrupt a program using CTRL+C. The signal handler can be run in a
thread different than the Python thread, in which case the test
deciding if the thread can handle signals is wrong.

On Windows, _PyEval_SignalReceived() now always sets eval_breaker to
1 since it cannot test _Py_ThreadCanHandleSignals(), and
  eval_frame_handle_pending() always calls
  _Py_ThreadCanHandleSignals() to recompute eval_breaker.

It is no longer possible to build the _ctypes extension module

* Call _PyTime_Init() and _PyWarnings_InitState() earlier during the

* The _warnings initialization function no longer call

* _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.

bpo-38823: Fix refleaks in _ctypes extension init (GH-23247)
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

reference on a heap type, but it is borrowed reference on a static
type.

bpo-40932: Note security caveat of shlex.quote on Windows (GH-21502)
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.

bpo-42140: Improve asyncio.wait function (GH-22938)
# 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.

bpo-42260: Fix _PyConfig_Read() if compute_path_config=0 (GH-23220)
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.

bpo-42260: Compute the path config in the main init (GH-23211)
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.

* 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.

bpo-41877 Check for asert, aseert, assrt in mocks (GH-23165)
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.
