Get assignments to .return working.
...
I really do not like the mechanism I currently use for handling pointer
derefences vs pointer assignments, but this will have to do for now until
I can get qfcc producing code again.

The first function seems to work fine, but there's a problems with the
scope of params causing params to get their knickers in a twist (tangled
linked list).

Simplify def handling, use far data.
...
Since there is now a proper symbol table, defs are now just references to
memory locations and the symbol table takes care of duplicates.
Also, start using far data for ObjQC structures.
The qfo functions have been stubbed out until I figure out what to do with
object files in the new scheme.
