Hi guys,

I was looking over the iso9660 code, and noticed that it was doing
endianness conversion via ad hoc *functions*, not even inlines; nor did
it take any advantage of the fact that iso9660 is bi-endian (has "all"
data in both bigendian and littleendian format.)

The attached patch fixes both.  It is against 2.4.4, but from the looks
of it it should patch against -ac as well.
