Jan Kara 979a6e28dd udf: Get rid of 0-length arrays in struct fileIdentDesc 
Get rid of 0-length arrays in struct fileIdentDesc. This requires a bit
of cleaning up as the second variable length array in this structure is
often used and the code abuses the fact that the first two arrays have
the same type and offset in struct fileIdentDesc.
