We would need to update this version for the release but, in fact,
it is not required for our publishing workflow; the hosted version
of the docs uses git commit/tag information in place of these
variables anyway.
Instead of updating the version, just remove these variables
entirely.

Currently we have some pre-rendered versions of certain diagrams
in SVG format. These diagrams have corresponding PlantUML source
that can be rendered automatically as part of the documentation
build, removing the need for any intermediate files.
This patch adds the Sphinx "plantuml" extension, replaces
references to the pre-rendered SVG files within the documents,
and finally removes the SVG files and helper script.
New requirements for building the docs are the
"sphinxcontrib-plantuml" Python module (added to the pip
requirements.txt file) and the Graphviz package (provides the
"dot" binary) which is in the Ubuntu package repositories.

Automatic labelling of document titles is a prerequisite for
converting the format of cross-document links. Sphinx will
generate (via the enabled extension) a hidden link target for
each document title and this can be referred to later, from
another page, to link to the target.
The plugin options being used require Sphinx >= 2.0.0 so a
requirements.txt file has been added. This file is used with
the pip package manager for Python so that the correct
dependencies are installed.

One of the current issues with the documentation is that terms and
abbreviations are frequently redefined. For example, we might have
a sentence like "... the SCP (System Control Processor) will ...".
These definitions might be repeated several times across pages, or
even within the same document. Equally, some of these abbreviations
are missed and are never expanded.
Sphinx provides a :term: keyword that takes some text and,
if that text is defined in a glossary document, links to its glossary
entry. Using this functionality will prevent repeated definitions
and will make the docs more maintainable by using a single
definition source.
The glossary added in this patch was created from a quick scrub of
the source code - there may be missing entries. The SDEI abbreviation
was used as an example.
Note that a global_substitutions file was created. This file contains
the RST 'replace' statements that convert plain text terms into linked
terms (by adding the ':term:' keyword to them). An example is:
.. |TF-A| replace:: :term:`TF-A`
The 'rst_prolog' variable in conf.py is used to inject this list of
replacements into each page. Terms must be surrounded with the pipe
character to be turned into links - this means that we can still
prevent certain terms from being linked if we don't want them to be.

Add the essentials for supporting a Sphinx documentation build:
- A makefile under docs/ to invoke Sphinx with the desired output
format
- A Sphinx master configuration file (conf.py)
- A single, top-level index page (index.rst)
- The TF.org logo that is integrated in the the sidebar of the
rendered output
