           Summary: metadatamux fails^WIS failure

The metadata unit tests are failing....

After looking a bit deeper at this, the problem is with the following pipeline:
gst-launch-0.10 videotestsrc num-buffers=1 ! jpegenc ! metadatamux ! fakesink

It will fail because... the (perfectly valid) jpeg buffer given to metadatamux
doesn't contain a 'APP0' marker (0xFFE0), which is
Even worse, it will fail if there is an 'APP0' marker but it's not just after
the SOI (Start Of Image 0xFFD8) marker.

metadatamux should (1) parse the buffer to figure out where the APP0 marker is
and (2) if not present create one.
