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).
