Adds documentation for V4L drivers.

The videobuf documentation is almost at rst format: we
just needed to add titles and add some code-blocks there
and that's it.

Also, add a notice that this framework is deprecated.

Make Sphinx happy with v4l2-framework.rst by putting all C
code inside code-block.

Please note that this is a poor man ReST conversion, as several
of those blocks should actually be converted to use :cpp:func:,
pointing to the kAPI auto-generated documentation.

The problem is that we currently lack kernel-doc documentation
for most of the stuff described there.

So, let's do a poor man's conversion. We should later address
this.

The conversion from DocBook required some fixes:

- Now, the C files with the exported symbols also need to be
  added. So, all headers need to be included twice: one to
  get the structs/enums/.. and another one for the functions;

- Notes should use the ReST tag, as kernel-doc doesn't
  recognizes it anymore;

- Identation needs to be fixed, as ReST uses it to identify
  when a format "tag" ends.

- Fix the cross-references at the media controller description.

There were lots of issues at the media controller side,
after the conversion:

- Some documentation at the header files weren't using the
  kernel-doc start block;

- Now, the C files with the exported symbols also need to be
  added. So, all headers need to be included twice: one to
  get the structs/enums/.. and another one for the functions;

- Notes should use the ReST tag, as kernel-doc doesn't

The conversion from DocBook lead into some conversion issues,
basically due to the lack of proper support at kernel-doc.

So, address them:

- Now, the C files with the exported symbols also need to be
  added. So, all headers need to be included twice: one to
  get the structs/enums/.. and another one for the functions;

- Notes should use the ReST tag, as kernel-doc doesn't
  recognizes it anymore;

- Identation needs to be fixed, as ReST uses it to identify
  when a format "tag" ends.

- kernel-doc doesn't escape things like *pointer, so we
  need to manually add a escape char before it.

- On some cases, kernel-doc conversion requires violating
  the 80-cols, as otherwise it won't properly parse the
  source code.

The rst2pdf tool is a very broken toolchain, with is not capable
of parsing complex documents. As such, it doesn't build the
media book, failing with:

	[ERROR] pdfbuilder.py:130 too many values to unpack

(using rst2pdf version 0.93.dev-r0 and Sphinx version 1.4.5)

So, make it build only the books we know that are safe to build.

Btw, with the standard Sphinx version shipped on Fedora 24 (Sphinx
1.3.1), rst2pdf doesn't build even the simple kernel-documentation,
failing with this error:
    writing Kernel... [ERROR] pdfbuilder.py:130 list index out of range

This is a known bug:
    https://github.com/sphinx-doc/sphinx/issues/1844

So, maybe we should just disable pdf generation from RST for good,
as I suspect that maintaining it with a broken toolchain will be a
big headache.

* 'docs-next' of git://git.lwn.net/linux:
  doc-rst: add an option to ignore DocBooks when generating docs
  workqueue: Fix a typo in workqueue.txt
  Doc: ocfs: Fix typo in filesystems/ocfs2-online-filecheck.txt
  Documentation/sphinx: skip build if user requested specific DOCBOOKS
  Documentation: add cleanmediadocs to the documentation targets

Those fixes came from patchs from Andrea for the old DocBook
documentation.

As we're removing it on Kernel 4.8, it doesn't make sense to
apply the original patches, but, as the typos were ported
to ReST, let's fix the issues there.

It is useful to have an index with all the book contents somewhere,
as it makes easier to seek for something. So, increase maxdepth
to 5 for the main index at the beginning of the book.

While here, remove the genindex content, as it is bogus.

This patch touches on places where it shouldn't: image

occurrences.

So, let's revert it.

This reverts commit ffbab694.

The timestamp field was split into rx_ts and tx_ts, and the rx/tx_status
fields were moved. Update the doc accordingly.

Also fix a bug that stated that a non-zero tx_status field signaled an
error. That's not true, since TX_STATUS_OK is 1, not 0.
