The contributors list needs some adjustments to be properly
formatted.

Also, this list has not been updated for a while. So, add a
notice about that.

The old ci.txt file had a very peculiar format, with doesn't
match any markup language I know. Change it to be on ReST
format, for it to be parsed by Sphinx.

Also, as this is an old document, add a note about it.

This file is using a markup-like language, but it is not quite
ReST. Convert it, and add a note pointing to the Wiki page with
the known supported hardware devices.

This document almost follows a markup language, but it is
not ReST. Fix it to be handled by Sphinx.

This file is almost at the ReST format, but some things need
to be fixed for it to be parsed.

Also, the documentation there is old. So, add a notice about
that.

Instead of keeping the introduction together with the
index, move it to a separate file, and add it via toctree
at the index.

The information there are outdated, so update it to point
to the right links.

There are several documentation stuff under Documentation/dvb.

Move them to Documentation/media/dvb-drivers and rename them to
rst, as they'll soon be converted to rst files.

No changes at the documentation.
