This script parses a header file and converts it into a
parsed-literal block, creating references for ioctls,
defines, typedefs, enums and structs.

It also allow an external file to modify the rules, in
order to fix the expressions.

There's no need for all caps at its name. As the book title is

The V4L2 is the only part of the doc that has the word "Specification"
and mentions its version on the title.

Having the version there was important in the past, while we were
getting rid of V4L version 1. But, as v1 is long gone, all it lasts
is history (with is, btw, covered on the spec). So, no need to keep
the version on its title.

So, rename it, to be more generic and look like the remaining
of the document.

The Digital TV section is ackward for two reasons:

  1) it is the only one with everything in upper case;
  2) its name is associated with the European digital TV standard.

Rename the part name, and add a notice that it refers to what's
known as "DVB API".

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.
