Fix the hordes of bogus defs.

They were caused by unused external defs, so not processing unused externs
in the first place is the simplest solution.

Delay initialization of obj_module_t as long as possible.

This keeps the type descriptor out of progs that never use any
Objective-QC features.

Emit code for jump tables.

With this, the entirety of the ruamoko tree builds (though the progs will
be broken in various ways: mostly unrelocated references).

it works for now.

Give - unary expressions special treatment.

The progs engine has no neg instruction, so need to implement -val as
nil - val

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.

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.
