ext/mad/: Add id3demuxbin (which is a simple bin consisting of id3demux and typefind), take over rank from id3demux, ...
Original commit message from CVS: * ext/mad/Makefile.am: * ext/mad/gstid3demuxbin.c: (gst_id3demux_bin_get_type), (gst_id3demux_bin_base_init), (gst_id3demux_bin_class_init), (gst_id3demux_bin_init), (gst_id3demux_bin_remove_pad), (found_type), (gst_id3demux_bin_change_state): * ext/mad/gstid3tag.c: (gst_id3_tag_add_src_pad), (gst_id3_tag_init), (gst_id3_tag_handle_event), (gst_id3_tag_src_link), (gst_id3_tag_chain), (gst_id3_tag_change_state), (plugin_init): * ext/mad/gstmad.h: Add id3demuxbin (which is a simple bin consisting of id3demux and typefind), take over rank from id3demux, remove typefind code from id3demux. Makes all broken mp3s that I know of work, and thereby fixes #152688.
