Andreas Rheinhardt 015950596c h264_mp4toannexb: Add a comment about possible overread 
Before reading a 16bit size field during parsing of extradata, no check
is performed to make sure that said length field is actually contained
in the extradata. Given that this overread is not dangerous (the extradata
is supposed to be padded), only a comment for it has been added; the error
itself will be detected as part of the normal check for overreads.
