Fix a whole pile of issues related to the failed attempt to increase

the number of types of relocation possible in the object file. (Now,
hopefully, working.)

Also change the object serialiser/deserialiser to never try to read or
write raw structures; it's way safer this way and we don't need the
performance boost any more.
