[MPlayer-dev-eng] Released Aud-X codec DLL

Thanx for all the remarks.
Indeed, this is a sort of mp3 extention.
The Aud-X algorithm could be an extention to any format,
because it contains the main audio data (mono or stereo stream, merged from
6 channels),
and some auxiliary information how to 'unmerge' the downmix.
It uses mp3 compression due to the popularity of this format.
(this also allows for mp3 backwards compatiblity)
