Original commit message from CVS: merge TYPEFIND branch. Major changes: - totally reworked type(find) system - all typefind functions are in gst/typefind now - more typefind functions then before - some plugins might fail to compile now because I don't have them installed and they a) require bytestream or b) haven't had their typefind fixed. Please fix those plugins and put the typefind functions into gst/typefind if they don't have dependencies
