Rework build_switch to use initialize_def.
...
This required support for label reference expressions, whose purpose is to
represent the address of a label.

Clean up all extra aborts, using internal_error instead.
...
Some internal_error calls have no message, but at least things will be more
consistent.

Bring back the unsigned type (PROGS version bump)
...
This is only low-level support (the unsigned keyword still does not work),
but sufficient to make switch statements using jump tables work.

Fix switch statements so the work in the new scheme.

Convert case labels to be the same type as the switch expression.
Use alias expressions for the various test expressions.

Alais the jump table's array to an integer.

As per the previous commit, I'm not sure this is the right thing to do, but
it works for now.

Make relocation records store the space of the relocation.
...
The space is meaningless for op_* relocations as they are always in the
code space, but def_* relocations need to know which space holds the
location to be adjusted.

Bring back convert_name(), but siimplified.

It is now mainly for converting __FILE__ etc, handling expression symbols,
and checking for undefined identifiers.

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.

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.
