Original commit message from CVS:
* ext/wavpack/gstwavpackdec.c: (gst_wavpack_dec_init),
(gst_wavpack_dec_format_samples),
(gst_wavpack_dec_clip_outgoing_buffer), (gst_wavpack_dec_chain),
(gst_wavpack_dec_change_state):
* ext/wavpack/gstwavpackdec.h:
Output audio in native byte order (which is also how we get
samples from wavpack); output samples with 21-24 bit depth
with 32 bit width (makes things easier for us).
