eb5581c7bd Fix class type encoding. 
First, the class def needed to be created before the class type, then the
def space indices had to be set early, otherwise the relocs wound up with
space 0 instead of the correct space.

c96718493a A bit of a cleanup before fixing class type defs. 
All internal structs now have "proper" names, and fit the naming convention
(eg, obj_module (like objective-c's types, but obj instead of objc). Some
redundant types got removed (holdovers from before proper struct tag
handling).

Also, it has proven to be unnecessary to build internal classes, so
make_class and make_class_struct are gone, too.

edd381931e Create obj_object after obj_class. 
obj_class is self-referential,but obj_object refers to obj_class. This gets
obj_class encoded properly.

96110a0f54 Treat messages to id and Class separately. 
As id and Class do not point to real objects as such, trying to get the
class from their types doesn't work, so instead send the message to a
"null" class that skips the method checks.

694b268f53 Correct the type of id. 
It should be struct obj_object * rather than Object *.

35a88d873c Rework the builtin class creation once again. 
Now the classes are built "properly" (using the same tools as the parser
itself), and the structs (obj_object, obj_class and obj_protocol) are built
separately, but using the class ivars.

b36bd3a988 Remove the list offsets from the class ivars. 
Even just before, type_obj_object, type_obj_class and type_obj_protocol
were a bit bogus (still are), but now the arrays used to list their ivars
are correct. I plan to create the above mentioned types using
class_to_struct to do it properly.

0cf16ac558 Make _OBJ_CLASS_foo the correct type. 
It needs to be type_obj_class, but I had gotten confused earlier when
rearranging the type names as I was having trouble with "not a class"
errors.

06fd912a09 Make super_class for the internal Protocol and Class objects. 
They're based on Object, and that needs to be represented properly.

86091856be Revamp the static class creation. 
Type names are cleaned up, as is the creation. Also, the class pointer in
the type encoding now gets emitted. However, Still need to actually create
_OBJ_CLASS_Class and fix the type encoding reloc handling in the linker.

d33d062bd1 Rearrange class_message_response. 
Even if an object doesn't seem to respond to a message, return the message
so unrelated warnings or errors don't occur.

eb86a66ce5 Do some class object type renaming. 
type_object -> type_obj_object
type_Class -> type_obj_class
type_ClassPtr -> type_Class

In the process, one more FIXME is gone :)

377f8f9d56 Use an explicit flag for class initialization. 
Much cleaner than messing with class_Class, which is about to go away.

7e293a38e8 Check for double-chaining of types. 
Chaining a type twice will form a loop in the type list, causing find_type
to go into an infinite loop.

ec42bde527 Make hash tables more const correct. 
And clean up the resulting mess :/

f14d8060e0 Merge qfpc into qfcc. 
Since gnu bison and flex are required anyway, no harm in using their api
prefix options. Now, qfcc can compile both QC/Ruamoko and Pascal files
(Pascal is (currently?) NOT supported in progs.src mode), selecting the
language based on the extension: .r, .qc and .c select QC/Ruamoko, .pas and
.p select Pascal, while anything else is treated as an object file (as
before).

bc1b483525 Nuke the rcsid stuff. 
It's pretty useless in git.

c6e0e094d8 Fix an unterminated array. 
That was sneaky. It took building qfcc on an arm to trigger that bug.

0f7390dd60 Clean up all the "set but not used" warnings. 
gcc on my system is failing to treat this specific warning as an error :/

f1d9570dc8 Fix constant value type handling. 
Rename immediate.[ch] to value.[ch] and clean up the mess.

Add convert_value() to convert the type of a value (only scalar types).

a919e5f619 Make class_check_ivars() use class_add_ivars() to add the ivars. 
This avoids implementation ivar blocks trashing the ivar offsets in
derived classes.

4192ef835c Delay initialization of obj_module_t as long as possible. 
This keeps the type descriptor out of progs that never use any
Objective-QC features.

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.

b2d4aee61e Reimplement selector expressions to work with far data. 
They currently execute a lea instruction every method call, but the
optimizer should take care of that once its written.

not repsonding to -alloc.

181596f5bf Make relocation records store the space of the relocation. 
The space is meaningless for op_* relocations as they are always in the
code space, but def_* relocations need to know which space holds the
location to be adjusted.

8c01497936 Give __obj_exec_class a sterner beating. 
When linking a def into a defspace, ensure it can be removed. This fixes
the missing __obj_exec_class def in qwaq.

1b8edc07c9 Adjust the offsets of ivars in derived classes. 
As ivar structs are not independent, their starting offset is not
necessarily zero (almost never will be for derived classes).

81125cff3a Creation of .ctor now mostly works. 
There seems to be problems with the actual code generation using incorrect
addresses, but a very simple test file compiles successfully.

da14c95bb8 Initialize current_symtab in class_init() when necessary. 
If an objective-qc symbol is the first token to be read, class_init() is
called before the parser gets a chance to perform the initialization
action. However, class_init() setting current_symtab if the first
objective-qc symbol is seen in a function body would be bad.
