These are passed and called as PyCFunction, however they are defined here without the (ignored) args parameter.

This works fine in some C compilers, but fails in webassembly or anything else that has strict function pointer call type checking.

…rics (GH-26013)

Added two new attributes to ``_GenericAlias``: 
* ``_typevar_types``, a single type or tuple of types indicating what types are treated as a ``TypeVar``. Used for ``isinstance`` checks.
* ``_paramspec_tvars ``, a boolean flag which guards special behavior for dealing with ``ParamSpec``. Setting it to ``True`` means this  class deals with ``ParamSpec``.

Ignore Py_DEPRECATED() warning on purpose.

Deprecate the following functions to configure the Python
initialization:

* PySys_AddWarnOption()
* PySys_AddWarnOptionUnicode()
* PySys_AddXOption()
* PySys_HasWarnOptions()
* Py_SetPath()
* Py_SetProgramName()
* Py_SetPythonHome()
* Py_SetStandardStreamEncoding()
* _Py_SetProgramFullPath()

Use the new PyConfig API of the Python Initialization Configuration
instead (PEP 587).

Add also references to PyFrame_BlockPop() removal.

The `PyModule_AddObjectRef` function doesn't steal a reference, so an extra `Py_DECREF` is needed.

Switch to lru_cache in urllib.parse.

urllib.parse now uses functool.lru_cache for its internal URL splitting and
quoting caches instead of rolling its own like its the 90s.

The undocumented internal Quoted class API is now deprecated
as it had no reason to be public and no existing OSS users were found.

The clear_cache() API remains undocumented but gets an explicit test as it
is used in a few projects' (twisted, gevent) tests as well as our own regrtest.
