Original commit message from CVS: * ext/wavpack/gstwavpackdec.c: (gst_wavpack_dec_setcaps), (gst_wavpack_dec_base_init), (gst_wavpack_dec_dispose), (gst_wavpack_dec_class_init), (gst_wavpack_dec_sink_event), (gst_wavpack_dec_init), (gst_wavpack_dec_format_samples), (gst_wavpack_dec_chain), (gst_wavpack_dec_plugin_init): Add debug category, use boilerplate macros, fix handling of widths of 32 bits. * ext/wavpack/gstwavpackparse.c: (gst_wavpack_parse_base_init), (gst_wavpack_parse_dispose), (gst_wavpack_parse_class_init), (gst_wavpack_parse_index_get_last_entry), (gst_wavpack_parse_index_get_entry_from_sample), (gst_wavpack_parse_index_append_entry), (gst_wavpack_parse_reset), (gst_wavpack_parse_src_query), (gst_wavpack_parse_scan_to_find_sample), (gst_wavpack_parse_send_newsegment), (gst_wavpack_parse_handle_seek_event), (gst_wavpack_parse_src_event), (gst_wavpack_parse_init), (gst_wavpack_parse_get_upstream_length), (gst_wavpack_parse_pull_buffer), (gst_wavpack_parse_create_src_pad), (gst_wavpack_parse_loop), (gst_wavpack_parse_change_state), (gst_wavepack_parse_sink_activate), (gst_wavepack_parse_sink_activate_pull), (gst_wavpack_parse_plugin_init): * ext/wavpack/gstwavpackparse.h: Rewrite a bit, mostly to fix flow logic and to make seeking work. Fix buffer/event refcounting. Add some debug statements. Add width of 32 to source pad template caps. Use boilerplate macros.
