Documentation/Changes: add minimal requirements for documentation build

As discussed at linux-doc ML, the best is to keep all documents
backward compatible with Sphinx version 1.2, as it is the latest
version found on some distros like Debian.

All books currently support it.

Please notice that, while it mentions the eventual need of
XeLaTex and texlive to build pdf files, this is not a minimal
requirement, as one could just be interested on building html
documents. Also, identifying the minimal requirements for
texlive packages is not trivial, as each distribution seems to
use different criteria on grouping LaTex functionalities.

While here, update the current kernel version to 4.x.

Sphinx
------
The ReST markups currently used by the Documentation/ files are meant to be
built with ``Sphinx`` version 1.2 or upper. If you're desiring to build
PDF outputs, it is recommended to use version 1.4.6.
.. note::
Please notice that, for PDF and LaTeX output, you'll also need ``XeLaTeX``
version 3.14159265. Depending on the distribution, you may also need
to install a series of ``texlive`` packages that provide the minimal
set of functionalities required for ``XeLaTex`` to work.
Other tools
-----------
In order to produce documentation from DocBook, you'll also need ``xmlto``.
Please notice, however, that we're currently migrating all documents to use
``Sphinx``.
