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.

There is a missing escape caracter, causing troubles at the
format of one of the paragraphs. Also, the ioctl description
was producing some warnings about wrong identation.

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.

This chapter is referenced on several parts of the extended
controls. Change the title to make it nicer where it is
referenced.

Ok, we might, instead, just change the name for the references
to only mention the oldest ioctl, but IMHO, it is better to
keep the name of all ioctls where it is referenced.

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.

Implements the reST flat-table directive.

The ``flat-table`` is a double-stage list similar to the ``list-table`` with
some additional features:

* column-span: with the role ``cspan`` a cell can be extended through
  additional columns

* row-span: with the role ``rspan`` a cell can be extended through
  additional rows

* auto span rightmost cell of a table row over the missing cells on the right
  side of that table-row.  With Option ``:fill-cells:`` this behavior can
  changed from *auto span* to *auto fill*, which automaticly inserts (empty)

list tables

  The *list tables* formats are double stage lists. Compared to the
  ASCII-art they migth be less comfortable for readers of the
  text-files. Their advantage is, that they are easy to create/modify
  and that the diff of a modification is much more meaningfull, because
  it is limited to the modified content.

The initial implementation was taken from the sphkerneldoc project [1]

list of supported DV timings for that pad.
