merge TYPEFIND branch. Major changes:

Browse source 
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

MP3 Audio Parser
================
This element acts as a parser for mpeg audio data. It's called 'mp3' but
in reality will work for any MPEG-1, MPEG-2, or MPEG-2.5 elemental audio
stream of any of Layers I, II, and III. It will not (currently, ever?)
handle MPEG-2 BC or NBC streams, as those have rather specialized needs
best served be a different filter.
It will take an mpeg audio stream in any form on its 'src' input, with any
buffer size, and split it into buffers containing a single frame each.
NOTE: ancillary data is not dealt with right now.
