These patches remove the ogg header packets from secondary chainged ogg streams from the demuxer.
First, a test utility is added to track what is currently happening with chained streams. Then the changes are introduced: the packet demuxing function is used to explicitely tell the demuxer to skip header packets. Also, the packet demuxing functions are adapted to properly copy extra data from the new chained streams so that decoding can keep happening. The diff from the test output makes it possible to follow what the changes do to the extracted streams.
