Log:
cd9660 pointer sign issues and missing __packed attribute
The isonum_* functions are defined to take unsigend char* as an argument,
but the structure fields are defined as char. Change to u_char where needed.
Probably the full structure should be changed, but I'm not sure about the
side affects.
While there, add __packed attribute.
