Stateless video decoding engines require both the MPEG-2 slices and
associated metadata from the video stream in order to decode frames.
This introduces definitions for a new pixel format, describing buffers
with MPEG-2 slice data, as well as control structure sfor passing the
frame metadata to drivers.
This is based on work from both Florent Revest and Hugues Fruchet.

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.

Sphinx 1.6 generates some LaTeX code before each table,
starting its own environment before calling tabulary,
apparently to improve table layout.
The problem is that such environment is incompatible with
adjustbox. While, in thesis, it should be possible to override
it or to redefine tabulary, I was unable to produce such patch.
Also, that would likely break on some future Sphinx version.
So, instead, let's just change the font size on bigger tables,
in order for them to fit into the page size. That is not as
good as adjustbox, and require some manual work, but it should
be less sensitive to Sphinx changes.
While here, adjust a few other tables whose text is exceeding
the cell boundaries.

There are several broken references there, due to the conversion to
C domain. Fix them using this shell script and manually adjust what's
broken:
# funcs is a file with the broken functions/references
for i in $(cat funcs|sort|uniq|perl -ne 'print "$1\n" if (m/(\S+)$/)'); do
i=${i//-/_}
echo $i
j=${i//_/-}
for k in $(git grep -l "_$j:" Documentation/); do
sed s,\_$j\:,"c\:type\:\: $i", <$k >a && mv a $k
done
for k in $(git grep -l "$j" Documentation/media/*.exceptions); do
sed s,$j,":c\:type\:\`$i\`", <$k >a && mv a $k
done
for k in $(git grep -l "$j" Documentation/); do
sed "s,:ref:\`$i <$j>\`,:c:type:\`$i\`," <$k >a && mv a $k
sed "s,:ref:\`$j\`,:c:type:\`$i\`," <$k >a && mv a $k
sed -E "s,:ref:\`(.*)<$j>\`,:c:type:\`\1<$i>\`," <$k >a && mv a $k
done
for k in $(git grep -l "<$j>" include/media); do
sed -E "s,:ref:\`(.*)<$j>\`,enum \&$i," <$k >a && mv a $k

Change the parse-headers.pl and the corresponding files to use
the C domain for enum references.

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

Sphinx is really pedantic with respect to the order where
table tags and references are created. Putting things at
the wrong order causes troubles.
The order that seems to work is:
.. raw:: latex
.. tabularcolumns::
.. _foo_name:
.. cssclass: longtable
.. flat-table::
Reorder the tags to the above order, to avoid troubles, and
fix remaining warnings introduced by media recent patches.

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;

So, let's revert it.
