Now that we have one syscall per page, using :cpp:function::
cleans up almost all warnings, with is a great thing.

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 layout of (table) captions in the RTD theme is a bit ugly and the
bordered, red colored of inline literals is a bit to gaudy. The
requirements has been discussed in the ML [1].

captions:

  - captions should have 100% (not 85%) font size
  - hide the permalink symbol as long as link is not hovered

inline literal:

  - drop the borderbox and red color

The default table layout of the RTD theme does not fit for vast tables,
like the ones we have in the linux_tv project. This has been discussed
on the ML [1].

The RTD theme is a two column layout, with a navigation column on the
left and a content column on the right:

content column

 RTD theme's default is 800px as max width for the content, but we have
 tables with tons of columns, which need the full width of the
 view-port (BTW: *full width* is what DocBook's HTML is).

table

   - sequences of whitespace should collapse into a single whitespace.
   - make the overflow auto (scrollbar if needed)
   - align caption "left" ("center" is unsuitable on vast tables)

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.
Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

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.

Sphinx actually doesn't numerate tables nor figures. So,
let's add a subtitle before each table. That makes them
"numerated".

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.
