ext/vorbis/vorbisdec.c: Cleanups. Use refcounting and DEBUG_OBJECT.
Original commit message from CVS: * ext/vorbis/vorbisdec.c: (vorbis_get_query_types), (vorbis_dec_convert), (vorbis_dec_src_query), (vorbis_dec_sink_query), (vorbis_dec_src_event), (vorbis_dec_sink_event), (vorbis_handle_identification_packet), (vorbis_dec_clean_queued), (vorbis_dec_push), (vorbis_handle_data_packet), (vorbis_dec_change_state): Cleanups. Use refcounting and DEBUG_OBJECT. Reset segment on flush, use code methods instead of our own wrong version. Fix potential memleak.
