* ./plugins/dummy/dec_dummy.c: new dummy decoder, for testing purposes.

   Usage: "--codec dummy" will use the dummy decoder for all streams, and
  save the stream to a stream.1242 file (where 1242 is the internal vlc
  object ID). If the input file was for instance an mpeg file, you can
  play one of the resulting files using an mp3 player.
