Massive ackbuilder refactor --- cleaner and more expressive. Lists

are automatically flattened (leading to better build files), and the
list and filename functions are vastly more orthogonal.

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.
