• Reverted to using the public argument parsing API
  :c:func:PyArg_ParseTupleAndKeywords under Python 3.12
  -- by :user:charles-dyfis-net and :user:webknjaz.

  The effect is that this change prevents build failures with
  clang 16.9.6 and gcc-14 reported in #926. It also
  fixes a segmentation fault crash caused by passing keyword
  arguments to :py:meth:MultiDict.getall() <multidict.MultiDict.getall> discovered by :user:jonaslb
  and :user:hroncok while examining the problem.

Packaging updates and notes for downstreams

• Stopped marking all files as installable package data
  -- by :user:webknjaz.

  This change helps setuptools understand that C-headers are
  not to be installed under :file:lib/python3.{x}/site-packages/.

• Started publishing pure-python wheels to be installed
  as a fallback -- by :user:webknjaz.

• Switched from setuptools' legacy backend (setuptools.build_meta:__legacy__)
  to the modern one (setuptools.build_meta) by actually specifying the
  the [build-system] build-backend option in :file:pyproject.toml
  -- by :user:Jackenmen.

Contributor-facing changes

• The test framework has been refactored. In the previous state, the circular
  imports reported in #837 caused the C-extension tests to be skipped.

  Now, there is a set of the pytest fixtures that is set up in a parametrized
  manner allowing to have a consistent way of accessing mirrored multidict
  implementations across all the tests.

  This change also implemented a pair of CLI flags (--c-extensions /
  --no-c-extensions) that allow to explicitly request deselecting the tests
  running against the C-extension.

• Updated the test pins lockfile used in the
  cibuildwheel test stage -- by :user:hoodmane.

  Related issues and pull requests on GitHub:
  #827.

• Added an explicit void for arguments in C-function signatures
  which addresses the following compiler warning:

  .. code-block:: console

  warning: a function declaration without a prototype is deprecated in all versions of C [-Wstrict-prototypes]

• An experimental Python 3.13 job now runs in the CI
  -- :user:webknjaz.

• Added test coverage for the :ref:and <python:and>, :ref:or <python:or>, :py:obj:sub <python:object.__sub__>, and
  :py:obj:xor <python:object.__xor__> operators in the
  :file:multidict/_multidict_base.py module. It also covers
  :py:data:NotImplemented and
  ":py:class:~typing.Iterable-but-not-:py:class:~typing.Set"
  cases there.
