ext/wavpack/gstwavpackdec.*: More clean-ups: remove most of the disfunctional correction pad stuff for now, if it eve...
Original commit message from CVS: * ext/wavpack/gstwavpackdec.c: (gst_wavpack_dec_base_init), (gst_wavpack_dec_class_init), (gst_wavpack_dec_init), (gst_wavpack_dec_finalize), (gst_wavpack_dec_format_samples), (gst_wavpack_dec_clip_outgoing_buffer), (gst_wavpack_dec_chain), (gst_wavpack_dec_sink_event), (gst_wavpack_dec_change_state): * ext/wavpack/gstwavpackdec.h: More clean-ups: remove most of the disfunctional correction pad stuff for now, if it ever gets implemented a lot of stuff will have to be rewritten anyway; redo chain function, move errors to end, error out instead of g_assert()ing. Also rename overly long variable 'wavpackdec' to just 'dec'; miscellaneous other small stuff.
