The usage of latexmk improves the PDF output, as it re-run
xelatex when it detects the need, in order to properly generate
indexes and cross-references.
As this is not a mandatory requirement, only suggest its
addition.

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.

RHEL 7.x and clone distros are shipped with Sphinx 1.1.x,
with is incompatible with Kernel ReST markups.
So, on those systems, the only alternative is to install
it via a Python virtual environment.
While seeking for "pip" on CentOS 7.3, I noticed that it
is not really needed, as python-virtualenv has its version
packaged there already. So, remove this from the list of
requirements for all distributions.
With regards to PDF, we need at least texlive-tabulary
extension, but that is not shipped there (at least on
CentOS). So, disable PDF packages as a whole.
Please notice, however, that texlive + amsmath is needed for
ReST to properly handle ReST ".. math::" tags. Yet, Sphinx
fall back to display the LaTeX math expressions as-is, if
such extension is not available.
So, let's just disable all texlive packages as a whole.

Add support for detecting and installing missing packages
on Mageia. I opted to use "urpmi" at the install instructions,
as this is present on Mageia since ever. Yet, if I were using
Mageia 6, I would likely be using "dnf", as it is, IMHO,
easier to use.
Tested with Mageia 6.

ImageMagick actually uses librsvg for conversions when converiting
from SVG (actually, it uses rsvg-convert). That causes the build to
fail with:
WARNING: Error #1 when calling: /usr/bin/convert /home/mchehab/docs/Documentation/media/uapi/v4l/selection.svg /home/mchehab/docs/Documentation/output/latex/selection.pdf
convert: delegate failed `'rsvg-convert' -o '%o' '%i'' @ error/delegate.c/InvokeDelegate/1919.
convert: unable to open file `/tmp/magick-8883oOQfHzrA5trM': No such file or directory @ error/constitute.c/ReadImage/544.
Add the corresponding dependencies.

On newer versions of graphviz packaging on Fedora, it is needed to

Instead of using 3 commands to install a virtualenv, use
a single one, reading the requirements from this file:

Solving Sphinx dependencies can be painful. Add a script to
check if everything is ok.
Tested on:
- Fedora 25 and 26;
- Ubuntu 17.04;
- OpenSuse Tumbleweed;
- Arch Linux;
- Gentoo.
