Write the linker output to progs.dat.
...
There is much breakage, but qfcc now produces a progs.dat from either
progs.src or object files. Better yet, the progs.src result is passed
through the linker, removing much duplicate code.

Yay, less duplicate code, and better yet, qfo_to_progs gets some much
needed testing :).

Handle relocs.
...
With this, the building of the work qfo seems to be almost finished, just
the special defs to go. Next step will be to stitch all the parts of the
work qfo into a real qfo.
However, still have to fix the relocs for the type descriptors, but they
are not critical to the linker's functioning.

More progress on the linker.

Need to finish up defs and handle relocs, and then take care of special

Make defrefs a little more stupid.

Stupid code does little well :P
I forgot that spaces get realloced, and I don't remember why I had the def
list pointer separate anyway.

Split the type processing into two passes.
...
This allows all duplicate types to be "merged" before adding any new
types, thus avoiding any accidental duplication caused by possible
differences in order between defs and the type descriptors.

This is mostly redundant, but it allows qfo spaces to get out of order
without breaking everything.
