The 'pre-skip' value representing encoder delay in the Opus
format is recorded once in the .opus representation, but for
WebM it's in the file both in the CodecDelay element and in
the CodecPrivate data. We now reject files where these two
fields don't match.
Our detodos.webm file was exactly this sort of mismatched
file. It has been renamed and added to the invalid file list
to verify we now reject it. A new detodos.webm replaces it,
remuxed from detodos.opus with a bugfixed mkvmerge.
Based on a patch by Jan Gerber.

This patch introduces two more MP3 test cases to exercise MP3FrameParser:
* vbr-head.mp3: This file contains a Xing header which gives an exact duration
of 10 seconds. However, it only contains 4 MP3 frames total for a real
duration of around 1 second. It is expected that we read the Xing header
and report 10 seconds.
* huge-id3.mp3: This file contains more than 130KB of ID3 tags. When we search
for MP3 frames, we give up after X KB of non-MP3 data. ID3 tags should not
count towards the non-MP3 count, since they can be very large. This test
case makes sure the skipping of ID3 tags works correctly.
