Subject wav files with extra chunks cause libxine to hang
(SF bug 1726288)

Given a wave file with chunks in the following order:

sox: Detected file format type: wav
sox: WAV Chunk fmt  length 18
sox: WAV Chunk bext length 602
sox: WAV Chunk data length 32366592
sox: WAV Chunk levl length 28228

causes code in demux_dts.c and demux_ac3.c to hang while searching for the
'data' chunk.
