Fix the missing type encoding for structures.
...
There should be a better way (probably by doing the encoding as needed
rather than in chain_type), but this seems to work for now.

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) bi = #0 ; error
.void (float y) ni = nil; OK
.void (float y) co = { }; error

Allow nil to be assigned to field variables.

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.

but offset relocs need to be used. However, as not all defs want offset
relocs, a flag has been added to the def struct.
