David Given 88bd7ce126 Remove defunct pmfiles.

 2016-06-03 13:56:50 +02:00
David Given ef8e6e25e0 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.

David Given e0c121d6e6 Use relocation enumerations rather than hard-coded values for relocation types 
(these were causing problems due to the enumeration values having changed).
