This PR updates docutils from 0.20.1 to 0.21.

Changelog

0.21

=========================

* General:

- Drop support for Python 3.7 and 3.8.

- Provide ``rst2*`` "console_scripts" `entry points`_
 (without the ``.py`` extension) instead of installing the
 ``rst2*.py`` `front end tools`_ in the binary PATH. []_

 Exceptions: ``rstpep2html.py`` and ``rst2odt_prepstyles.py``:

 - Use ``docutils --reader=pep --writer=pep_html`` for a PEP preview. []_
 - Use ``python -m docutils.writers.odf_odt.prepstyles``
   to `strip the page size`__ from an ODT writer stylesheet.

 __ docs/user/odt.htmlpage-size

.. [] Some Linux distributions already use the short names.
.. [] The final rendering is done by a Sphinx-based build system
      (cf. :PEP:`676`).

* reStructuredText:

- Use the same CSV format for the ``:header:`` option and the main data
 of the "csv-table_" directive.

- New option "loading" for the `"image" directive`_.
 Sets the new attribute loading__ of the <image> doctree element.

__ docs/ref/doctree.htmlloading

* Configuration changes:

- New configuration setting root_prefix_.
 Configurable root directory for included files.

- New configuration setting sources_ for the "buildhtml.py" application.

- Simpler and more secure `input encoding`_ default behaviour:

 Do not use the locale encoding as fallback if Python is started in
 `UTF-8 mode`_. Stop using "latin1" as second fallback.

 Remove BOM (U+FEFF ZWNBSP at start of data) only if the `input_encoding`_
 configuration setting is None, '', 'utf-8-sig', 'utf-16', or 'utf-32'.
 Do not remove other ZWNBSPs.

* Output changes:

HTML5:
 Stop setting the "footnote-reference" class value for footnote
 references. Use the CSS selector ``[role="doc-noteref"]``
 (works since Docutils 0.18, see minimal.css for examples).

 Fix MathML rendering problems in Chrome/Chromium based browsers.

 Embed SVG images as ``<svg>`` instead of data-URI.

manpage:
 Use .EE/.EX macros for literal blocks.

 Render URI references (do not use .UR/.UE).

 Use box option for tables.

* Removed objects:

`docutils.nodes.reprunicode`, `docutils.nodes.ensure_str()`
 Python 2 compatibility hacks
`docutils.utils.Reporter.set_conditions()`
 obsolete
`docutils.core.Publisher.setup_option_parser()`
 internal, obsolete

* New files:

``docutils/writers/html5_polyglot/italic-field-names.css``
 Alternative style for Docutils field-lists.

* Removed files:

``install.py``, ``setup.py``
 Metadata is now stored in ``pyproject.toml``,
 supported by pip_ since version 19.0 (2019-01-22).
 See README__ for installation alternatives.
