c404f5d4f0 docs: Add more information to the HTML sidebar
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.

bd5d1cc8ff docs: Don't wire font sizes for HTML output
The alabaster theme likes to provide explicit sizes for fonts, which
overrides the users's own browser settings and is guaranteed to displease
folks.  Set the font size to "inherit" so that the users browser settings
control the font size they get.  We can use the font_size configuration
option for the main body font (changing the size I'd already put there),
but the sidebar size can only be set via custom CSS.

eaf710ceb5 docs: improve the HTML formatting of kerneldoc comments
Make a few changes to cause functions documented by kerneldoc to stand out
better in the rendered documentation.  Specifically, change kernel-doc to
put the description section into a ".. container::" section, then add a bit
of CSS to indent that section relative to the function prototype (or struct
or enum definition).  Tweak a few other CSS parameters while in the
neighborhood to improve the formatting.

2056b920c6 docs: tweak some Alabaster style parameters
This is just the beginning: tighten up the layout a bit to improve the
information density in the browser.  Also reconfigure the page width in
terms of character units (em) rather than pixels, making it more
display-independent.  To that end, add a custom.css file to
tweak Alabaster CSS settings.

a6fb8b5acf docs: add support for RTD dark mode
This is actually an overlay on the top of the RTD theme, which
requires to include first the RTD theme.

It should be noticed that, when the dark theme is used, the
DOCS_CSS files won't be the last CSS themes. So, it won't
override the dark.css style by default. So, it is needed
to force the them override with "!important".

This small script, for instance, produces a nice output with
the RTD dark theme:

	DOCS_THEME=sphinx_rtd_dark_mode
	cat << EOF > dark_override.css
	  html body {
	    font-family: arial,helvetica,sans-serif;
	  }
	  html[data-theme='dark'] body {
	    color: white !important;
	  }
	  html[data-theme='dark'] .sig-name {
	    color: green !important;
	  }
	  html[data-theme='dark'] .wy-menu-vertical a {
	    color: #ffcc00 !important;
	  }
	  html[data-theme="dark"] h1, html[data-theme="dark"] h2, html[data-theme="dark"] h3 {
	    color: #ffcc00 !important;
	  }
	  html[data-theme="dark"] h4, html[data-theme="dark"] h5, html[data-theme="dark"] h6 {
	    color: #ffcc00 !important;
	  }
	  html[data-theme="dark"] h7, html[data-theme="dark"] h8, html[data-theme="dark"] h9 {
	    color: #ffcc00 !important;

1b1438b535 doc-rst: Reduce CSS padding around Field
Right now any ":Field Name: Field Contents" lines end up with significant
padding due to CSS from the "table" CSS which rightly needs padding to
make tables readable. However, field lists don't need this as they tend
to be stacked together. The future heavy use of fields in the parsed
MAINTAINERS file needs this cleaned up, and existing users look better
too. Note the needless white space (and misalignment of name/contents)
between "Date" and "Author":

https://www.kernel.org/doc/html/latest/accounting/psi.html

This patch fixes this by lowering the padding with a more specific CSS.

44ba0bb4f2 docs: improve readability for people with poorer eyesight
My eyesight is not in good shape, which means that I have difficulty
reading the online Linux documentation.  Specifically, body text is
oddly small compared to list items and the contrast of various text
elements is too low for me to be able to see easily.

Therefore, alter the HTML theme overrides to make the text larger and
increase the contrast for better visibility, and trust the typeface
choices of the reader's browser.

For the PDF output, increase the text size, use a sans-serif typeface
for sans-serif text, and use a serif typeface for "roman" serif text.

4c0477899f docs RTD theme: code-block with line nos - lines and line numbers don't line up.
In a code-block with line numbers (option :lineno:) there is a
misalignment of the rendered source code lines on the right side and the
line numbers on the left side.

  https://github.com/rtfd/sphinx_rtd_theme/issues/419

Since this issue is reported to the RTD theme project, it might be fixed
in the future (take this as a interim solution).

916f677ada docs RDT theme: fix bottom margin of lists items
List items with two ore more blocks are not well rendered. E.g. the gap
between last block (l1-b2) of the first list item and the following list
item (L2) is to small::

    * L1 xxxxxxxxxx
      xxxxxxxxxxxxx

      l1-b2 xxxxxxx
      xxxxxxxxxxxxx
    * L2 xxxxxxxxxx
      xxxxxxxxxxxxx

So that it can be read more liquidly, a distance was added to the last
block (l1-b2)::

    * L1 xxxxxxxxxx
      xxxxxxxxxxxxx

      l1-b2 xxxxxxx
      xxxxxxxxxxxxx

    * L2 xxxxxxxxxx
      xxxxxxxxxxxxx

02bafd96f3 This is the documentation update pull for the 4.9 merge window.
The Sphinx transition is still creating a fair amount of work.  Here we
 have a number of fixes and, importantly, a proper PDF output solution,
 thanks to Jani Nikula, Mauro Carvalho Chehab and Markus Heiser.
 
 I've started a couple of new books: a driver API book (based on the old
 device-drivers.tmpl) and a development tools book.  Both are meant to show
 how we can integrate together our existing documentation into a more
 coherent and accessible whole.  It involves moving some stuff around and
 formatting changes, but, I think, the results are worth it.  The good news
 is that most of our existing Documentation/*.txt files are *almost* in RST
 format already; the amount of messing around required is minimal.
 
 And, of course, there's the usual set of updates, typo fixes, and more.

ef88f10eb8 [media] doc-rst: backward compatibility with older Sphinx versions
Sphinx is really evil when an older version finds an extra
attribute for the :toctree: tag: it simply ignores everything
and produce documents without any chapter inside!

As we're now using tags available only on Sphinx 1.4.x, we
need to use some creative ways to add a title before the
table of contents. Do that by using a css class.

4eb40f14dc doc-rst: customize RTD theme, captions & inline literal
The layout of (table) captions in the RTD theme is a bit ugly and the
bordered, red colored of inline literals is a bit to gaudy. The
requirements has been discussed in the ML [1].

captions:

  - captions should have 100% (not 85%) font size
  - hide the permalink symbol as long as link is not hovered

inline literal:

  - drop the borderbox and red color

9abaf979ab doc-rst: customize RTD theme, table & full width
The default table layout of the RTD theme does not fit for vast tables,
like the ones we have in the linux_tv project. This has been discussed
on the ML [1].

The RTD theme is a two column layout, with a navigation column on the
left and a content column on the right:

content column

 RTD theme's default is 800px as max width for the content, but we have
 tables with tons of columns, which need the full width of the
 view-port (BTW: *full width* is what DocBook's HTML is).

table

   - sequences of whitespace should collapse into a single whitespace.
   - make the overflow auto (scrollbar if needed)
   - align caption "left" ("center" is unsuitable on vast tables)
