b50b392746 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

87b240f469 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.

4336fc2c73 Move method function defs into the far data space.
As they are never referenced directly by instructions, there's no need for
them to be in the near data space, taking precious def locations.

5fa349927f Preserve the ivars inheritance chain across build_struct().
build_struct() unlinks the structure symbol table from its parent, but
that breaks the ivar inheritance chain.

f1fccb19dd Allow same-type re-declarations of uninitialized variables.
This is especially important for declaring variables that were previously

Bill Currie
d75c35ba30 Allow qc style function params.
Due to ambiguities in the grammar, qc-style function params and c-style
function params had to be completely separated. This means that qc-style
functions can not use pointers and must use qc-style function declarations
for parameters, and c-style functions must use c-style param declarations.
While this rule is tedious for converting the Ruamoko library, it does
actually make for a more consistent language.

67957a14df Bring back convert_name(), but siimplified.

2203903bb2 Temporarily splice the class's ivar chain into the symbol table.
The root class's ivar symbol table needs to be connected to the global
symbol table while building the current class's ivar symbol table. This
allows access to other classes and typedefs.

d12cdca758 Functions and enums now seem to be working properly.
find_type now operates recursively (depth-first) so built up typechains
work as expected.

@overload is treated as a specifier (directly as a storage class, similaar
to typedef).

ac91e9376b The big type-system rewrite. Horribly broken :)
While broken, it is good enough to compile modulo.r.

This gives qfcc C's type system with QC specifics bolted on top (rather
than trying to cram C's type system into QC's). Pointers and arrays now
use C syntax and semantics (though I think there's a lot of breakage in
there at the moment). Functions themselves are still dual mode: both QC
style and C style are available.

It segs when it tries to link, but that's because a real object file has

ea3895805b 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.

Objective-C, but after working on Forge, I now know otherwise.

dc5bafb8fb Minimal error recovery.
No more bailing on the first syntax error. While the recovery is not
perfect (things can get right twisted), qfcc will now continue parsing
after a syntax error.
