The "Table of Contents" of a PDF file is generated only once,
at the beginning fo the output. It doesn't produce it on
each part.
So, don't output this text on each part of the document.

A literal box provides a better visual when pdf and html output
is generated for things like the output of a sysfs devnode.
It alsod matches other conventions used within the media book.
So, use it.
While here, use literals for protocol names.

Commit 70b074df4ed1 ("media: fix pdf build with Spinx 1.6") caused
a regression at Sphinx 1.4 PDF build: although it produces a full
document in batch mode, it returns errors on interactive mode:
[63]
Runaway argument?
{\relax
! Paragraph ended before \multicolumn was complete.
<to be read again>
\par
l.7703 \hline\end{tabulary}
The error seems to be due to some bug at Sphinx PDF output:
when multicolumns is used, it doesn't accept an empty string.
Just removing the :cpan:`1` and replacing by two empty
columns fix the issue.

On tests with Spinx 1.4, some tables are still writing text
outside cells. Adjust those tables.
PS.: As this was revisited several times, I suspect that this
will only be fully fixed if we add tabularcolumns to all tables
at the V4L2 part of the book.

The Tuner Audio Matrix table is broken: the first row has 7
columns instead of 6, causing it to be parsed wrong and displayed
very badly on PDF output.
Fix it and adjust the table to look nice at PDF output

In the past, V4L2 versions were 0.x.y, but that changed years
ago. Since Kernel 3.1, however, the numbering schema was changed
to match the Kernel version.
However, the presented example still uses the old numerating
schema, with is a misleading information.
So, update it to the new schema.

Several ioctls are missing descriptions for the third argument
of the ioctl() command. They should have a description, as
otherwise the output won't be ok, and will sound like something
is missing.
So, add them.

Usually, CA messages are sent/received via reading/writing at
the CA device node. However, two drivers (dst_ca and firedtv-ci)
also implement it via ioctls.
Apparently, on both cases, the net result is the same.
Anyway, let's document it.

Do minor editorial changes to improve documentation readability:
- mark literals as such;
- add table markups to hint sizes;
- define what PES means;
- instead of hardcoding devnode numbers to zero (like adapter0/) use a
question mark, to indicate that multiple devnodes may exist;
- add cross-references where useful.

In the past, the documentation used to say that, if a CRC error
was found, a "-ECRC" error would be returned. That's not true:
the DVB core will just silently ignore such errors.

The usage of the term "DVB" at the dvb API docs is confusing,
as, right now, it can refer to either the European digital TV
standard or to the subsystem.
So, prefer calling it as "Digital TV" on most places, to avoid
ambiguity.

The device node name for CA is wrong since ever. I suspect

There are several issues on the return value for ioctls:
- Text is confusing;
- Some error codes don't exist;
- The non-generic error codes should come before the text
that points to the generic error codes;
- Tables don't contain column size hints;
- Some references are not marked as such.
Correct them.

Instead of having one chapter per file, place all of them at
the same chapter. That better organize the chapters at the uAPI
documentation.
As a side effect, now all uAPI headers are at the same page,
at the html output, with makes easier to use it as a reference
index for the spec.

For most of the stuff there, documenting is easy, as the
header file contains information.
Yet, I was unable to document two data structs:
ca_msg and ca_descr

This ioctl seems to be some attempt to support a feature
at the bt8xx dst_ca driver. Yet, as said there, it
"needs more work". Right now, the code there is just
a boilerplate.
At the end of the day, no driver uses this ioctl, nor it is
documented anywhere (except for "needs more work").
So, get rid of it.

Now that frontend.h contains most documentation for the frontend,
remove the duplicated information from Documentation/ and use the

Both CA and decoders are optional. Also, the presence or
absence has nothing to do on being a PCI card or not.
Nowadays, most hardware leaves the decoders to either the
GPU or to some ISP inside the SoC, instead of implementing
it inside the Digital TV part of the device.
So, change the wording to reflect the hardware changes.
