It turns out this patch doesn't properly handle files where
FooterPartition isn't properly set in all partitions. mxfenc's output is
an example of this - FooterPartition is only properly set in the header.
I opted to deal with this in the demuxer since mxfenc is probably not
the only writer to do this.
Anyway, the attached patch takes any non-zero FooterPartition value and
sticks it in MXFContext for later use.
