Add a new sidebar template that creates a more RTD-like "fisheye" view of
the current place in the document hierarchy. It is far from ideal, but
some readers may find it better for navigating through the documentation as
a whole.
Add some CSS trickery as well to make the table of contents less intrusive
when viewing the pages on a small screen.

On distros whose texlive packaging is fine-grained, texlive-xecjk
can be installed/removed independently of other texlive packages.
Conditionally loading xeCJK depending only on the existence of the
"Noto Sans CJK SC" font might end up in xelatex error of
"xeCJK.sty not found!".
Improve the situation by testing existence of xeCJK.sty before
loading it.
This is useful on RHEL 9 and its clone distros where texlive-xecjk
doesn't work at the moment due to a missing dependency [1].
"make pdfdocs" for non-CJK contents should work after removing
texlive-xecjk.

The automarkup code tries to look up symbols once as a function, and once
as a macro. The Sphinx C domain code, though, totally ignores that
distinction and will return the same results either way. So just look
things up once and be done with it; the resulting output does not change,
but htmldocs build time drops by about 5%.

The automarkup code tries to create a lot of cross-references that don't
exist. Cross-reference lookups are expensive, especially in later versions
of Sphinx, so there is value in avoiding unnecessary ones. Remember
attempts that failed and do not retry them.
This improves the htmldocs build time by 5-10% depending on the phase of
the moon and other factors.

Quote from Jon's remark [1]:
I do notice that Documentation/conf.py is getting large and
unapproachable. At some future point, it might be nice to pull
all of the latex stuff out into a separate file where it won't
scare people who stumble into it by accident.
Pull LaTeX preamble settings added since commit 3b4c963243 ("docs:

sphinx/kerneldoc-preamble.sty.
It will be copied to the build directory by the added
"latex_additional_files" setting in conf.py.
As a bonus, LaTeX/TeX code can be maintained without escaping backslashes.

Using convert(1) of ImageMagick for SVG -> PDF conversion results in
PDFs containing raster (bitmap) images which sometimes look blurry.
Ideally speaking, SVG to PDF conversion should retain vector graphics
in SVG.
rsvg-convert(1) can do such conversions with regard to SVG files
generated by dot(1).
Unfortunately, rsvg-convert(1) does not cover some of SVG features
specific to Inkscape.
inkscape(1) of Inkscape naturally covers such SVG features.
So add a route in svg2pdf() so that inkscape(1) is used when it is
available.
Note:
After this change, if you have Inkscape installed, ImageMagick nor
librsvg are not required.

To prevent any regression on existing build systems, limit the
fallback of converting DOT -> raster PDF only when both of the
following conditions are met.
o dot(1) doesn't support -Tpdf
o rsvg-convert(1) is not found
While we are here, add kernellog.verbose messages related to
rsvg-convert, 'dot -Tpdf', and 'dot -Tsvg' commands.

On openSUSE, dot(1) command does not support direct PDF output.
On other distros, generated PDF images have unnecessarily wide margins,
especially for small graphs.
By using dot(1) for DOT -> SVG, then rsvg-convert(1) for SVG -> PDF,
more optimal PDF images can be obtained, with the bonus of improved
portability across various distros.
Add rules in kfigure.py so that the above mentioned route is taken
when rsvg-convert(1) is available.
Note that rsvg-convert(1) is recommended by sphinx_pre_install.
So it is most likely that existing systems for building pdfdocs have
rsvg-convert(1) installed.
Note:
SVG features supported by rsvg-convert(1) vary depending on its
version and distro config.
For example, the one found on Ubuntu Bionic (version 2.40.20) does
poor job in rendering some of SVG files drawn by Inkscape.
SVG files generated by dot(1) are converted nicely even with such
old versions of rsvg-convert.
So this change does not affect the quality of such figures in any
way.

Since commit d18b01789a ("docs: Add automatic cross-reference for
documentation pages"), references that were already explicitly defined
with "ref:" and referred to other pages with a path have been doubled.
This is reported as the following error by Firefox:
Start tag "a" seen but an element of the same type was already open.
End tag "a" violates nesting rules.
As well as the invalid HTML, this also obscures the URI fragment links
to subsections because the second link overrides the first. For example
on the page admin-guide/hw-vuln/mds.html the last link should be to the
"Default Mitigations" subsection using a # URI fragment:
admin-guide/hw-vuln/l1tf.html#default-mitigations
But it is obsured by a second link to the whole page:
admin-guide/hw-vuln/l1tf.html
The full HTML with the double <a> tags looks like this:
<a class="reference internal" href="l1tf.html#default-mitigations">
<span class="std std-ref">
<a class="reference internal" href="l1tf.html">
<span class="doc">L1TF - L1 Terminal Fault</span>
</a>
</span>
</a>
After this commit, there is only a single link:
<a class="reference internal" href="l1tf.html#default-mitigations">
<span class="std std-ref">Documentation/admin-guide/hw-vuln//l1tf.rst</span>
</a>
Now that the second link is removed, the browser correctly jumps to the
default-mitigations subsection when clicking the link.
The fix is to check that nodes in the document to be modified are not
already references. A reference is counted as any text that is a
descendant of a reference type node. Only plain text should be converted
to new references, otherwise the doubling occurs.
Testing
=======
* Test that the build stdout is the same (ignoring ordering), and that
no new warnings are printed.
* Diff all .html files and check that the only modifications occur
to the bad double links.
* The auto linking of bare references to pages without "ref:" is still
working.

Previously, a cross-reference to another document could only be created
by writing the full path to the document starting from the
Documentation/ directory.
Extend this to also allow relative paths to be used. A relative path
would be just the path, like ../filename.rst, while the absolute path
still needs to start from Documentation, like Documentation/filename.rst.
As part of this change, the .rst extension is now required for both
types of paths, since not requiring it would cause the regex to be too
generic.

Sphinx 3.1 introduced namespaces for C cross-references. With this,
each C domain type/function declaration is put inside the namespace that
was active at the time of its declaration.
Add support for automatic cross-referencing inside C namespaces by
checking whether the corresponding source file had a C namespace Sphinx
directive, and if so, try cross-referencing inside of it before going to
the global scope.
This assumes there's only one namespace (if any) per rst file.

The Sphinx docutils parser is lazy: if the content is bigger than
a certain number of lines, it silenlty stops parsing it,
producing an incomplete content. This seems to be worse on newer
Sphinx versions, like 2.0.
So, change the logic to parse the contents per input file.

Just like kernel-doc extension, we need to be able to identify
what part of an imported document has issues, as reporting them
as:
get_abi.pl rest --dir $srctree/Documentation/ABI/obsolete --rst-source:1689: ERROR: Unexpected indentation.
Makes a lot harder for someone to fix.
It should be noticed that it the line which will be reported is
the line where the "What:" definition is, and not the line
with actually has an error.

The same way kerneldoc.py needed changes to work with newer
Sphinx, this script needs the same changes.
While here, reorganize the include order to match kerneldoc.py.

The ABI documentation is special: it is not plain text files,
but, instead, files with an strict format, as specified by
Documentation/ABI/README.
Add a parser for it.

The :c:type:`foo` only works properly with structs before
Sphinx 3.x.
On Sphinx 3.x, structs should now be declared using the
.. c:struct, and referenced via :c:struct tag.
As we now have the automarkup.py macro, that automatically
convert:
struct foo
into cross-references, let's get rid of that, solving
several warnings when building docs with Sphinx 3.x.

Sphinx 3 added support for declaring C macros with parameters using the
:c:macro role.
To support automarkup for both functions and parametrized macros using
the same regex (words ending in ()), try to cross-reference to both, and
only fall back to regular text if neither exist.

With the transition to Sphinx 3, new warnings were caused by
automarkup, exposing bugs in the name matching.
When automarkup parsed a text like "struct struct" in the documentation,
it tried to cross-reference to a "struct" symbol, which is recognized as
a C reserved word by Sphinx 3, generating a warning.
Add some C reserved words (only the ones that were causing warnings) to
a list and skip them while trying to cross-reference.

With the transition to Sphinx 3, new warnings were generated by
automarkup, exposing bugs in the regexes.
The warnings were caused by the expressions matching words in the
translated versions of the documentation, since any unicode character
was matched.
Fix the regular expression by making the C regexes use ASCII and
ensuring the expressions only match the beginning of words,
in order to avoid warnings like this:
WARNING: Unparseable C cross-reference: '调用debugfs_rename'
That's probably due to the lack of using spaces between words
on Chinese.

While Sphinx 2 used a single c:type role for struct, union, enum and
typedef, Sphinx 3 uses a specific role for each one.
To keep backward compatibility, detect the Sphinx version and use the
correct roles for that version.
