o renommage arbitraire et totalitaire de idctmmx.S en vdec_idctmmx.S 

 o correction d'une typo d�bile dans audio_output au commit pr�c�dent
 o b_stereo est remplac� par i_channels
 o suppression de la structure aout_dsp_t dont les membres d�pendant
  de l'output se retrouve dans aout_*_sys_t, et les autres directement
  dans aout_thread_t, on se fait pas chier.
