Make the iff demuxer send the whole audio chunk to the decoder as a single packet, move stereo interleaving from the iff demuxer to the decoder, and introduce an 8svx_raw decoder which performs stereo interleaving. This is required for handling stereo data correctly, indeed samples are stored like: LLLLLL....RRRRRR that is all left samples are at the beginning of the chunk, all right samples at the end, so it is necessary to store and process the whole buffer in order to decode each frame. Thus the decoder needs all the audio chunk before it can return interleaved data. Fix decoding of files 8svx_exp.iff and 8svx_fib.iff, fix trac issue #169.
