The 'fiel' atoms can be found in H.264 tracks clobbering the extradata.
MJPEG supports non field based extradata, and this data should be
preserved when copying.

fixes memleak of side data

This fixes demuxing of file where the first packet is not audio. Such files
are generated by our idroq muxer. It also fixes demuxing of audio only
idroq files.

Compared to just overwriting the old extradata, this has the
advantage of letting the decoder know exactly when the
extradata changed (otherwise it is changed immediately when the
new extradata packet is demuxed, even if there's old queued packets
awaiting to be decoded). This makes it easier for decoders to
actually react to the change, so they won't have to inspect
the extradata for each packet to see if it might have changed.

This works when sequentially playing a file with sample rate
changes, but if seeking past a new extradata packet in the
file, it obviously doesn't work properly. That case doesn't
work in flash player either, so it's probably ok not to handle
it.

This fixes SIGSEGV on files with both CBR and VBR index segments (zzuf6.mxf).

Without this certain files could get the demuxer stuck in a loop

Specially crafted files can lead the parsing code to take too long.
We fix a lot of these problems by not allowing local tags to extend past the
end of the set and not allowing other KLVs to be read past the end of
themselves.

This fixes SIGSEGV on files where this is actually the case, such as zzuf4.mxf

This can happen if an index table segment has a very large IndexStartPosition.
zzuf3.mxf is an example of such a file.

This fixes the infinite loop with zzuf2.mxf

This fixes SIGSEGV with zzuf1.mxf

and thus cannot be used

This avoids a SIGFPE if SampleRate is missing or set to naughty values.

Only the OPAtom demuxing logic is guaranteed to have index tables, meaning OP1a
files that lack an index would cause SIGSEGV.

Without this the demuxer will SIGSEGV on files with IndexEntryCount < IndexDuration

The last entry is the total size of the essence container.
Previously a TemporalOffset error would be logged, even though segments like
