Subject: ext/wavpack/gstwavpackdec.c: Fix caps after previous change to byte
 order endianness.

Original commit message from CVS:
* ext/wavpack/gstwavpackdec.c: (gst_wavpack_dec_chain):
Fix caps after previous change to byte order endianness.
* ext/wavpack/gstwavpackparse.c: (gst_wavpack_parse_reset),
(gst_wavpack_parse_sink_event), (gst_wavpack_parse_init),
(gst_wavpack_parse_loop):
* ext/wavpack/gstwavpackparse.h:
Queue incoming events if there's no source pad yet and
send them downstream later when the pad is there.
