Originally, at the DocBook, the "Byte Order" were a single
paragraph with the string that follows it. The conversion
broke it, and, sometimes, it added an extra dot.

When we wrote the media controller's section, we re-used the
V4L, just because we were lazy to create a brand new DocBook.

Yet, it is a little ackward to have it mixed with V4L. So,
move it to its own directory, in order to have it better
organized.

Using auto-generated links is dangerous, as there are multiple
definitions for syscalls (at least one on each book part).

So, reference them by their explicit reference.

I used this small script to help writing this patch:

for i in $(git grep -l "c:func:"); do perl -ne 's/\:c\:func:\`(open|close|read|poll|write|select|mmap|munmap|ioctl)\(\)`/:ref:`$1() <func-$1>`/; print $_' < $i >a && mv a $i; done

The right way to use it seems to do suscript is to use
this pattern: "\ :sub:"

Make sure all places of the media document will fit, by
using this script:

$n=0;
while (<>) {
	$n++;
	$t = $_;
	@matches = $t =~ m/(..\:sub\:)/g;
	foreach my $m (@matches) {
		$m =~ m/(.)(.)(\:sub\:)/;
		$s1=$1;
		$s2=$2;
		$s3=$3;
		next if (($s1 eq "\\") && ($s2 eq " "));
		if ($s2 eq " ") {
			$t =~ s/$s1$s2$s3/$s1\\$s2$s3/;
			next;
		}
		$t =~ s/$s1$s2$s3/$s1$s2\\ $s3/;
	}
	print $t;
}

And running it with:

for i in $(git grep -l sub Documentation/linux_tv/); do ./sub.pl $i >a && mv a $i; done

All error codes should be const. Most are, but there are
lots of places where we forgot to add <constant> at the DocBook.

Fix those via this small script:
	for i in $(git grep -lE "\s+E[A-Z]+\b" Documentation/linux_tv/); do perl -ne 's,([^\`])\b(E[A-Z]+)\b,\1``\2``,g; print $_' <$i >a && mv a $i; done

As there are false positives, we needed to merge only the changes
that make sense, skipping the c blocks and skipping things like
EDID, EN, ETS that were also converted by the above code.

The conversion on this file didn't end too well. fix the found
issues:

1) Sphinix seems to not allow things like *foo :ref:`bar`*. At least
on this document, it did the wrong thing. So, change the logic to
something that will work fine with ReST format;

2) Some ioctl pointers were not looking nice;

3) the captions on the examples got discarded;

4) The notes specific to each example were not converted well.
Again, we'll need to replace it for a simpler design, as Sphinx
is a way more limited than DocBook.

The c language parser checks if there are duplicated object
definitions. That causes lots of warnings like:
	WARNING: duplicate C object description of ioctl

Let's remove those by telling Sphinx that the language for
those objects are c++. The look of the descriptions will
be close, and the warnings will be gone.

Please notice that we had to keep a few of them as C, as
the c++ parser seems to be broken when it finds an enum.

Yet, this reduced from 219 warnings to 143, with is
a good thing.
