2a7c7cba38 docs: Remove "could not extract kernel version" warning
This warning will happen for every normal kernel docs build and doesn't
carry any useful information.  Should anybody actually depend on this
"version" variable (which isn't clear to me), the "unknown version" value
will be clue enough.

54d6d73f50 docs-rst: don't require adjustbox anymore
Only the media PDF book was requiring adjustbox, in order to
scale big tables. That worked pretty good with Sphinx versions
1.4 and 1.5, but Spinx 1.6 changed the way tables are produced,
by introducing some weird macros before tabulary.
That causes adjustbox to fail. So, it can't be used anymore,
and its usage was removed from the media book.

So, let's remove it from conf.py and sphinx-pre-install.

9fdcd6afd8 docs-rst: conf.py: only setup notice box colors if Sphinx < 1.6
Sphinx 1.5 added a new way to change backward colors for note
boxes, but kept backward compatibility with 1.4. On Sphinx 1.6,
the old way stopped working, in favor of a new less hackish
way.

Unfortunately, this is currently too buggy to be used, and
the old way doesn't work anymore. So, we have no option but
to stick with boring notice boxes.

One example of such bug is the notice that it is inside
struct v4l2_plane, at the "bytesused" field.

At least, add a notice about how to use, as maybe some day
the bug will vanish.

646056ec3b docs-rst: fix verbatim font size on tables
On Sphinx 1.6, fancy boxes are used for verbatim. The sphinx.sty
sets verbatim font is always \small. That causes a problem

5148e6ab76 docs-rst: pdf: use same vertical margin on all Sphinx versions
Currently, on Sphinx up to version 1.4, pdf output uses a vertical
margin of 1 inch. For upper versions, it uses a margin of 0.5 inches.

That causes both page headers and footers to be very close to the margin
of the sheet. Not all printers support writing like that.

Also, there's no reason why the layout for newer versions would be
different than for previous ones.

So, standardize it, by always setting to 1 inch.

db6ccf23e8 docs-rst: automatically convert Graphviz and SVG images
This patch brings scalable figure, image handling and a concept to
embed *render* markups:

* DOT (http://www.graphviz.org)
* SVG

For image handling use the 'image' replacement::

    .. kernel-image::  svg_image.svg
       :alt:    simple SVG image

For figure handling use the 'figure' replacement::

    .. kernel-figure::  svg_image.svg
       :alt:    simple SVG image

       SVG image example

Embed *render* markups (or languages) like Graphviz's **DOT** is
provided by the *render* directive.::

  .. kernel-render:: DOT
     :alt: foobar digraph
     :caption: Embedded **DOT** (Graphviz) code.

     digraph foo {
      "bar" -> "baz";
     }

The *render* directive is a concept to integrate *render* markups and
languages, yet supported markups:

* DOT: render embedded Graphviz's **DOT**
* SVG: render embedded Scalable Vector Graphics (**SVG**)

e2a91f4f42 docs-rst: fix LaTeX \DURole renewcommand with Sphinx 1.3+
PDF build on Kernel 4.9-rc? returns an error with Sphinx 1.3.x
and Sphinx 1.4.x, when trying to solve some cross-references.

The solution is to redefine the \DURole macro.

However, this is redefined too late. Move such redefinition to
LaTeX preamble and bind it to just the Sphinx versions where the
error is known to be present.

Tested by building the documentation on interactive mode:
	make PDFLATEX=xelatex -C Documentation/output/./latex

b459106ea4 Documentation/sphinx: set literal block highlight language to none
Set the default highlight language to "none", i.e. do not try to guess
the language and do automatic syntax highlighting on literal blocks.

Eyeballing around the generated documentation, we don't seem to actually
have a lot of literal blocks that would benefit from syntax
highlighting. The C code blocks we do have are typically very short, and
most of the literal blocks are things that shouldn't be highlighted (or,
do not have a pygments lexer). This seems to be true for literal blocks
both in the rst source files and in source code comments.

Not highlighting code is never wrong, but guessing the language wrong
almost invariably leads to silly or confusing highlighting.

At the time of writing, admin-guide/oops-tracing.rst and
admin-guide/ramoops.rst contain good examples of 1) a small C code
snippet not highlighted, 2) a hex dump highligted as who knows what, 3)
device tree block highlighted as C or maybe Python, 4) a terminal
interaction highlighted as code in some language, and finally, 5) some C
code snippets correctly identified as C. I think we're better off
disabling language guessing, and going by explicitly identified
languages for longer code blocks.

It is still possible to enable highlighting on an rst source file basis
using the highlight directive:

.. higlight:: language

and on a literal block basis using the code-block directive:

.. code-block:: language

See http://www.sphinx-doc.org/en/latest/markup/code.html for details.

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.

f0ddda3e94 docs-rst: create a book for the development process
Now that the files at Documentation/development-process/
were converted to ReST, make create a book at Sphinx.

As we'll have other books related to the development process,
we'll add it as a sub-book.

41cff161fe docs-rst: Use better colors for note/warning/attention boxes
Instead of painting the box with gray, let's use a colored
box. IMHO, that makes easier to warn users about some issue
pointed by the Sphinx. It also matches to what we do already
with the HTML output.

aa4e37a3d1 docs-rst: conf.py: adjust the size of .. note:: tag
While the current implementation works well when using as a
paragraph, it doesn't work properly if inside a table. As we
have quite a few such cases, fix the logic to take the column
size into account.

PS.: I took the logic there from the latest version of Sphinx.sty

This extension will be used by the media books.

The name of the math image extension changed on Sphinx 1.4.x,
according with:
	http://www.sphinx-doc.org/en/stable/ext/math.html#module-sphinx.ext.imgmath

Let's autodetect, to keep building with versions < 1.4.

pdflatex doesn't accept using some UTF-8 chars, like
"equal or less than" or "equal or greater than" chars. However,
the media documents use them. So, we need to use XeLaTeX for
conversion, and a font that accepts such characters.
