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.

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
defs (@self etc), but things are getting very close.

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.

First stage of the linker rewrite.
...
Strings, code and data spaces are "merged". Various offsets are updated.
Still to do:
o Merge reloc, def, function and line data.
o Merge type data.
o Update def and function type pointers.
o Resolve external defs and check for duplicate defs.
o Perform relocations.
o anything else I've forgotten :)

Rewrite much to use symbols and symtabs. Gut emit.c. Massive breakage.
...
That which isn't rewritten is horribly broken. However, this does include a
nice mechanism for building QC structs for emitting data.
emit.c has been gutted in the spirit of "throw one away".
There is much work to be done to get even variables emitted, let alone
code. Things should be a little more fun from here on.
