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.

struct def_s;
enum storage_class_e;
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.

} struct_def_t;
[qfcc] Add a handle type for engine resources I never liked the various hacks I had come up with for representing resource handles in Ruamoko. Structs with an int were awkward to test, pointers and ints could be modified, etc etc. The new @handle keyword (@ used to keep handle free for use) works just like struct, union and enum in syntax, but creates an opaque type suitable for a 32-bit handle. The backing type is a function so v6 progs can use it without (all the necessary opcodes exist) and no modifications were needed for type-checking in binary expressions, but only assignment and comparisons are supported, and (of course) nil. Tested using cbuf_t and QFile: seems to work as desired. I had considered 64-bit handles, but really, if more than 4G resource objects are needed, I'm not sure QF can handle the game. However, that limit is per resource manager, not total.

struct symbol_s *find_handle (struct symbol_s *tag, struct type_s *type);
[qfcc] Support C's full type system Along with QuakeC's, of course. This fixes type typeredef2 test (a lot of work for one little syntax error). Unfortunately, it came at the cost of requiring `>>` in front of state expressions on C-style functions (QuakeC-style functions are unaffected). Also, there are now two shift/reduce conflicts with structs and unions (but these same conflicts are in gcc 3.4). This has highlighted the need for having the equivalent of the expression tree for the declaration system as there are now several hacks to deal with the separation of types and declarators. But that's a job for another week. The grammar constructs for declarations come from gcc 3.4's parser (I think it's the last version of gcc that used bison. Also, 3.4 is still GPL 2, so no chance of an issue there).

[qfcc] Adjust ivar offsets to preserve alignment As a class's ivars are built up by inheritance, but with only that class's ivars in the symbol table, is is necessary to include an offset based on the super class's ivars in order to ensure alignments are respected. This is achieved via the new `base` parameter to build_struct(), which is used to offset the current size while calculating the aligned offset of the symbols. The parameter is ignored for unions, as they always start at 0. The ivars for the current class still have a base offset of 0 until they are actually added to the class. Fixes #29

struct symbol_s *find_enum (struct symbol_s *tag);
struct symtab_s *start_enum (struct symbol_s *enm);
Delay calling find_type for enums. As find_type encodes the type too, calling find_type before the enumerators have been created causes the type encoding to lose the enumerators.
