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.

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.

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 ffbab694.

Those characters are used for citations. Better to escape, to
avoid them to be misinterpreted.

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.

On the syscall conversions, we used uppercase for the sections,
but this is too bold. So, convert them to Camel Case, as it
looks visually better.

The syscall pages are written to be used also as man-pages.

However, they don't match the format used by kernel-doc
generated pages from DocBook. Rewrite them to match it.

One side effect is that now all such pages at the book
will have the same format, reducing the format differences
between DVB and the other parts of the book.

Let's remove bad whitespaces on the entire book.

That helps to avoid mixing whitespace removal with other
patches.

The conversion script added some comments at the end.
They point to the original DocBook files, with will be
removed after the manual fixes. So, they'll be pointing
to nowere. So, remove those comments.

They'll be forever stored at the Kernel tree. So, if
someone wants the references, it is just a matter of
looking at the backlog.

On several places, instead of using references, the code was
using some other tag. Not sure if this was due to the conversion,
or if something were already wrong on the DocBook. In any case,
let's fix them.

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 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.

As VIDIOC_G_foo is the reference used for VIDIOC_S_foo and
VIDIOC_TRY_foo, we need to explicitly name the reference, as
otherwise, it will mention the three ioctls altogether, with
is not what we want.

There were lots of consts at the media docbook that should
be, instead, references. Convert the ones that can easily
be done by an automatic script.

Due to a limitation at the DocBook language, the references
were using lowercase and slashes, instead of the name of the
ioctls. On ReST, make them identical. This will hopefully
help to cleanup the code a little bit.
