bpo-39491: Merge PEP 593 (typing.Annotated) support (#18260)
* bpo-39491: Merge PEP 593 (typing.Annotated) support

PEP 593 has been accepted some time ago. I got a green light for merging
this from Till, so I went ahead and combined the code contributed to
typing_extensions[1] and the documentation from the PEP 593 text[2].

My changes were limited to:

* removing code designed for typing_extensions to run on older Python
  versions
* removing some irrelevant parts of the PEP text when copying it over as
  documentation and otherwise changing few small bits to better serve
  the purpose
* changing the get_type_hints signature to match reality (parameter
  names)

I wasn't entirely sure how to go about crediting the authors but I used
my best judgment, let me know if something needs changing in this
regard.

Python Documentation README
~~~~~~~~~~~~~~~~~~~~~~~~~~~

This directory contains the reStructuredText (reST) sources to the Python
documentation.  You don't need to build them yourself, `prebuilt versions are
available <https://docs.python.org/dev/download.html>`_.

Documentation on authoring Python documentation, including information about
both style and markup, is available in the "`Documenting Python
<https://devguide.python.org/documenting/>`_" chapter of the
developers guide.


Building the docs
=================

The documentation is built with several tools which are not included in this
tree but are maintained separately and are available from
`PyPI <https://pypi.org/>`_.

* `Sphinx <https://pypi.org/project/Sphinx/>`_
* `blurb <https://pypi.org/project/blurb/>`_
* `python-docs-theme <https://pypi.org/project/python-docs-theme/>`_

The easiest way to install these tools is to create a virtual environment and
install the tools into there.

Using make
----------

To get started on UNIX, you can create a virtual environment with the command ::

  make venv

That will install all the tools necessary to build the documentation. Assuming
the virtual environment was created in the ``venv`` directory (the default;
configurable with the VENVDIR variable), you can run the following command to
build the HTML output files::

  make html

By default, if the virtual environment is not created, the Makefile will
look for instances of sphinxbuild and blurb installed on your process PATH
(configurable with the SPHINXBUILD and BLURB variables).

On Windows, we try to emulate the Makefile as closely as possible with a
``make.bat`` file. If you need to specify the Python interpreter to use,
set the PYTHON environment variable instead.

Available make targets are:

* "clean", which removes all build files.

* "venv", which creates a virtual environment with all necessary tools
  installed.

* "html", which builds standalone HTML files for offline viewing.

* "htmlview", which re-uses the "html" builder, but then opens the main page
  in your default web browser.

* "htmlhelp", which builds HTML files and a HTML Help project file usable to
  convert them into a single Compiled HTML (.chm) file -- these are popular
  under Microsoft Windows, but very handy on every platform.

  To create the CHM file, you need to run the Microsoft HTML Help Workshop
  over the generated project (.hhp) file.  The make.bat script does this for
  you on Windows.

* "latex", which builds LaTeX source files as input to "pdflatex" to produce
  PDF documents.

* "text", which builds a plain text file for each source file.

* "epub", which builds an EPUB document, suitable to be viewed on e-book
  readers.

* "linkcheck", which checks all external references to see whether they are
  broken, redirected or malformed, and outputs this information to stdout as
  well as a plain-text (.txt) file.

* "changes", which builds an overview over all versionadded/versionchanged/
  deprecated items in the current version. This is meant as a help for the
  writer of the "What's New" document.

* "coverage", which builds a coverage overview for standard library modules and
  C API.

* "pydoc-topics", which builds a Python module containing a dictionary with
  plain text documentation for the labels defined in
  `tools/pyspecific.py` -- pydoc needs these to show topic and keyword help.

* "suspicious", which checks the parsed markup for text that looks like
  malformed and thus unconverted reST.

* "check", which checks for frequent markup errors.

* "serve", which serves the build/html directory on port 8000.

* "dist", (Unix only) which creates distributable archives of HTML, text,
  PDF, and EPUB builds.


Without make
------------

First, install the tool dependencies from PyPI.

Then, from the ``Doc`` directory, run ::

   sphinx-build -b<builder> . build/<builder>

where ``<builder>`` is one of html, text, latex, or htmlhelp (for explanations
see the make targets above).

Deprecation header
==================

You can define the ``outdated`` variable in ``html_context`` to show a
red banner on each page redirecting to the "latest" version.

The link points to the same page on ``/3/``, sadly for the moment the
language is lost during the process.
