Original commit message from CVS: New typefind system: * bytestream is now part of the core * all plugins have been modified to use this new typefind system * asf typefinding added * mpeg video stream typefiding removed because it's broken * duplicate typefind entries removed * extra id3 typefinding added, because we've seen 4 types of files (riff/wav, flac, vorbis, mp3) with id3 headers and each of these needs to work. Instead, I've added an id3 element and let it redo typefiding after the id3 header. this needs a hack because spider only typefinds once. We can remove this hack once spider supports multiple typefinds. * with all this, mp3 typefinding is semi-rewritten * id3 typefinding in flac/vorbis is removed, it's no longer needed * fixed spider and gst-typefind to use this, too. * Other general cleanups
