Use the new buffer clipping function from gstaudio here and require gst-plugins-base CVS.

Original commit message from CVS:
* configure.ac:
* ext/wavpack/gstwavpackdec.c: (gst_wavpack_dec_reset),
(gst_wavpack_dec_chain), (gst_wavpack_dec_sink_event):
Use the new buffer clipping function from gstaudio here and
require gst-plugins-base CVS.
* tests/check/elements/wavpackdec.c: (GST_START_TEST):
For framed Wavpack buffers we require a valid timestamp.
