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
declared external.

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.

0b5565396b Add a class type to symbols and rework the CLASS_NAME handling. 
This fixes the problem with [Array alloc] producing a warning about Class
not repsonding to -alloc.

76034861c9 Implement direct ivar access in methods. 
A warning needs to be generated for access to ivars in a class method, but
it seems to work (unable to check due to other errors).

Rename class_pointer_def() to class_pointer_symbol() and use it when a
class name is used as the receiver of a message.

67957a14df Bring back convert_name(), but siimplified. 
It is now mainly for converting __FILE__ etc, handling expression symbols,
and checking for undefined identifiers.

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.

a648f043de Give functions their own defspace.

34ffce50fa Ensure current_symtab gets set at the start of parsing. 
current_symtab must be set even if the first thing encountered is a syntax
error.
