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 :)

Give type data a null pointer.
...
Pointers to the void type descriptor looked just like null pointers and
that was terribly confusing. Avoid that confusion by pre-allocating a
small amount of data in order to reserve space for a null descriptor.

Fix field def allocation for function fields.
...
Assignment of nil to a field function is permitted, but trying to use one
as a builtin or as a normal function is treated as an error.
.void (float y) func; OK
.void (float y) bi = #0 ; error
.void (float y) ni = nil; OK
.void (float y) co = { }; error

Allow nil to be assigned to field variables.

Note, this is the field variable itself, not the field in the entity.
eg:
.integer x = nil;

Use special treatment for .float ()foo; functions.
...
The parser wants to treat .float () foo; as a function returning a float
field, but qcc treats it as a field holding a function variable.
Fortuantely, field types are always "simple" (ie, at worst, just more
field type wrappers around the non-field type), so all that's needed to
obtain qcc grammar is to reach into the field type layers and do the
function type calculation based on the non-field type found there.

Clean up objective-qc type encoding.
...
Structures etc now never encode the fields as well (I might revert that
at some time). Type parsing has been removed: it has proven unnecessary
and overly complicated, and the new qfo encoding should be more useful.

Allow defs to specify use of offset relocations.
...
Access to struct fields in near data can be done using only one operand,
but offset relocs need to be used. However, as not all defs want offset
relocs, a flag has been added to the def struct.
