* Added a third argument to aout_OutputNextBuffer. In case the buffer

  received does not start exactly at the given date, it indicates if the
  output plug-in is able to compensate for the drift (for instance on
  startup, or with S/PDIF packets), or if we need the aout core to
  resample the coming buffers. It is currently unimplemented.
