+ libmad_input now takes one frame at a time (see mad_adec.h for defines)
+ audio_linear_dither() gives better sound quality then s24_to_s16_pcm(),
  but also makes audio artefacts louder so disabled it for now (see file
  mad_libmad.c)
+ cleaned up libmad_output (see file mad_libmad.c)
+ cleaned up InitThread (see file mad_adec.c)
+ Made buffer size match libmad's expectations (see file mad_adec.h)
+ updated documentation

  * COMPLETE CVS BREAKAGE !! The MAIN branch is going to be a playground
    for my nevrotic and destructive pulsions during the next few hours!

  * If you want to test vlc, please use the v0_2_92_branch branch.

  * Stuff currently working:
     - direct to YUV buffer decoding
     - non-ugly subtitle blending
     - XVideo and SDL video output

  * Stuff currently utterly broken:
     - aspect ratio
     - software rendering (ie, all other video output plugins)

  * Additional misc changes:
     - Renamed spu_dec to spudec and mad_adec to mad to stay coherent with
       other plugins. Also, renamed mpeg to mpeg_system.
     - Added jobi to the AUTHORS file.
     - Factored code common to vout_x11.c and vout_xvideo.c.
