* Header cleaning: filled all empty authors fields, added CVS $Id stuff.
  * Fixes to aout_darwin.c by Colin Delacroix <colin@zoy.org>.
  * Fixes to configure.in, Makefile.in and main.c (Altivec detection)
    by Eugenio Jarosiewicz <ej0@cise.ufl.edu>.
  * Added Colin and Eugenio to the AUTHORS file.

  . moved the MPEG audio decoder to the new bitstream

    I wasn't sure whether the bits counting method was effective to
  skip ancillary data at the end of a frame, but I kept it for
  safety. There is still a lot to optimize in the bit counting, like
  unrolling the first iteration of some loops, but I don't know if
  it would be worth it. The other solution would have been to look for
  a startcode after eache frame, without caring about the ancillary bits.

  . cleaning in the SPU decoder.

 . this is a coding style patch which removes all "foo(bar){" constructions
   and most of the tabulations.
 . also, fixed a bug in the default subtitle track.
 . and made a few error messages more explicit, ie. changed "error: %s" to
   "foo error: couldn't initialize bar (%s)"

 . split the audio decoder into adec_generic, adec_layer1 and adec_layer2
    (no new code added)

 . fixed audio syncword detection for mpeg 1 streams (hopefully)
    FIXME: can anyone confirm we can get rid of adec_byte_stream_next
    in audio_decoder_thread.c now that we have the new input ?

 . fixed Layer 2 Mono decoding.
    FIXME: who created freq_table ? what was the rationale for it, and
    where does it come from ?
    FIXME: how can we spare the extra DCT in audio_decoder.c:707 ? I'm too
    tired to think about it.

 . proposal: splitting audio_decoder.c in one file per layer.

 . moins de warnings dans la YUV MMX

licences. Et puis �a peut arriver � tout le monde :)

* support du layer 1 mono et stereo
* support du layer 2 stereo (j'ai pas encore fait le mono)
* support des low bitrates proposes par le mpeg2 (non teste)
* passage des tests de compliance mpeg :)
* moins de macros qu'avant, mais je dois encore propriser un peu le code.
