Use float for enum defs in v6 progs.
...
The values are (or should be!) written as floats, so don't give any
debuggers hernias when displaying enums in v6 progs.

Change pointer_t to unsigned and clean up the mess.
...
It doesn't make sense to have negative pointers. The size of the commit is
from enabling gcc's -Wtype-limits warning and cleaning up that mess too.

Add a param flag to defs.
...
It is necessary to know if a def is a function parameter so it can be
treated as initialized by the flow analyzer. The support for the flag in
object files is, at this stage, purely for debugging purposes.

Make .type_encodings more useful.

Rather than just a pointer, it is now a struct with a pointer and size
indicating the extent of the type encodings block.

Fix class type encoding.
...
First, the class def needed to be created before the class type, then the
def space indices had to be set early, otherwise the relocs wound up with
space 0 instead of the correct space.

Make the type encodings findable.
...
The base of the type encodings block is given by the .type_encodings def.
The block begins with a "null" type (4 words of 0), followed by the first
type encoding.
At some stage, I will need to add information for extended def information
(32 bit offset, type encoding, other?), but this is good for initial
testing.

Remove the auxfunction manipulation from the compiler proper.

It was broken code in the first place (realloc and pointers), and is

Undo the offset relocation of local defs.
...
The debug info expects local defs to be 0 based, so once relocations in
the progs data have been completed, undo the local def offset relocation
so that the correct offsets will be written to the debug info.

There is much breakage, but qfcc now produces a progs.dat from either

through the linker, removing much duplicate code.

First stage of the linker rewrite.

Strings, code and data spaces are "merged". Various offsets are updated.
Still to do:

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 :)

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.
