vidix: drop VIDIX support

By now VIDIX is too obscure to justify the amount of code and
complexity it requires in the sources. Although there is no pressing
need to drop it just now from a code point of view, I'll rather remove
it before release than release with VIDIX support and then drop it
later.

Some of the manpage mentions of VIDIX were in "this option supported
for these VOs" lists that looked outdated and failed to mention vdpau
for example. Replace such incorrect lists with a generic "not
supported for all VOs" mention.
