8b5efbeb97 [media] buffer.rst: Adjust table columns for LaTeX output
The table columns are not properly displayed. Also, some
tables are too big to fit into just one page. So, fix them,
in order to better display the tables.

b315a63bf5 [media] pixfmt-packed-rgb.rst: adjust tables to fit in LaTeX
Adjust the tables to fit at the LaTeX and PDF outputs.

I wrote a previous patch RFC to show the big table in landscape,
but it makes harder to read on displays.

So, instead, let's use the adjustbox to shrink the size of those
long tables, as the table size can still be visible on screen,
and it is a way better to read in horizontal position and
visible if printed.

5bd4bb7817 [media] docs-rst: add tabularcolumns to all tables
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;

48f6993793 [media] vidioc-querycap.rst: Better format tables on PDF output
Both tables on this rst file were not shown right, as they miss
the proper tag (tabularcolumns) to specify the column widths
required for PDF and LaTeX output.

Also, the second table is too big to fit into one page. So,
it should use the longtable class to allow it to be split into
two pages.
