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.

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.

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.

Now that frontend.h contains most documentation for the frontend,
remove the duplicated information from Documentation/ and use the
kernel-doc auto-generated one instead.
That should simplify maintainership of DVB frontend uAPI, as most
of the documentation will stick with the header file.

Now that we moved away from the :ref: type of references,
we need to update the exceptions lists.

instead of declaring the uAPI structs using usual refs, e. g.:
.. _foo-struct:
Use the C domain way:
.. c:type:: foo_struct
This way, the kAPI documentation can use cross-references to
point to the uAPI symbols.
That solves about ~100 undefined warnings like:
WARNING: c:type reference target not found: foo_struct

Name all ioctl references and make them match the ioctls that
are documented. That will improve the cross-reference index,
as it will have all ioctls and syscalls there.
While here, improve the documentation, marking the deprecated
ioctls, and making the non-deprecated ones more like the rest
of the media book.
Also, add a notice for ioctls that still require documentation.

Now that we have an override for the c domain that will do
the right thing for the Kernel, stop abusing on the cpp
domain.

LaTeX doesn't handle too well auto-width on tables, and ReST
markup requires an special tag to give it the needed hints.
As we're using A4 paper, we have 17cm of useful spaces. As
most media tables have widths, let's use it to generate the
needed via the following perl script:
my ($line_size, $table_header, $has_cols) = (17.5, 0, 0);
my $out;
my $header = "";
my @widths = ();
sub round { $_[0] > 0 ? int($_[0] + .5) : -int(-$_[0] + .5) }
while (<>) {
if (!$table_header) {
$has_cols = 1 if (m/..\s+tabularcolumns::/);
if (m/..\s+flat-table::/) {
$table_header = 1;
$header = $_;
next;
}
$out .= $_;
next;
}
$header .= $_;
@widths = split(/ /, $1) if (m/:widths:\s+(.*)/);
if (m/^\n$/) {
if (!$has_cols && @widths) {
my ($tot, $t, $i) = (0, 0, 0);
foreach my $v(@widths) { $tot += $v; };
$out .= ".. tabularcolumns:: |";
for ($i = 0; $i < scalar @widths - 1; $i++) {
my $v = $widths[$i];
my $w = round(10 * ($v * $line_size) / $tot) / 10;
$out .= sprintf "p{%.1fcm}|", $w;
$t += $w;
}
my $w = $line_size - $t;
$out .= sprintf "p{%.1fcm}|\n\n", $w;
}
$out .= $header;
$table_header = 0;
$has_cols = 0;
$header = "";
@widths = ();
}
}
print $out;

Change multi-line note tags to be more symetric, e. g. not starting

This patch touches on places where it shouldn't: image
files and code examples. Also, it doesn't fix all array
occurrences.
So, let's revert it.
This reverts commit ffbab694ed.

There are several notes and warning mesages in the middle of
the media docbook. Use the ReST tags for that, as it makes
them visually better and hightlights them.
While here, modify a few ones to make them clearer.

The name of the subsystem is "media", and not "linux_tv". Also,
as we plan to add other stuff there in the future, let's
rename also the media uAPI book to media_uapi, to make it
clearer.
No functional changes.
