#656: LXF demuxer fails on new Leitch files

-------------------------------------+-------------------------------------
FFmpeg/avformat fails to read files produced by newer Leitch/Harris
servers (*.lxf). According to what I've learned, the file header and
packet headers have grown a few bytes in the new version. The byte count
for the headers have been updated, but I suspect that the lxf demuxer in
avformat has these values hard coded. This is the output of FFmpeg:
[lxf @ 020F9F40] checksum error
[lxf @ 020F9F40] expected 120 B size header, got 0
All the samples I have are very big (3GB+), so I can't send the files
easily.
