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.

On some syscall descriptions, the tables are described after
the return value. Do that inside descriptions.

There are some ioctls in upper case. This is not the standard.
Put them on lowercase, to match what's done with other ioctls.

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.

Just like V4L, split the DVB function calls into one file per
system call. This is a requirement for the man pages creator
on Sphinx to work, and makes the document easier to maintain.

Let's remove bad whitespaces on the entire book.

That helps to avoid mixing whitespace removal with other
patches.

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

Parsing this file were causing lots of warnings with sphinx,
due to the c function prototypes.

Fix that by prepending them with .. c:function::

While here, use the same way we document man-like pages,
at the V4L side of the book and add escapes to asterisks.

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.

The asterisks cause parsing warnings with Sphinx:
	Documentation/linux_tv/media/dvb/fe_property_parameters:954: WARNING: Inline substitution_reference start-string without end-string.
	/devel/v4l/patchwork/Documentation/linux_tv/media/dvb/fe_property_parameters:993: WARNING: Inline emphasis start-string without end-string.

On the first warning, the ISDB-T layer enabled description is a
kind of ackward. Improve it.

For the second one, IMHO, it is clearer to use [A-C], as it
shows what are the real possibilities, than using asterisk.

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.

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.
