23a38738fc Massive whitespace cleanup. 
Lots of trailing whitespace and otherwise blank lines.

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.

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.

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.

5f3c1872b9 Put class and category reference/name symbols in the symbol table.

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.

3c64ae7b66 Fix overzealous type merging. 
Use the type name instead of the symbol table for comparing
struct/union/enum types.

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).

2f7b892452 Fix passing messages to classes. 
Rename class_pointer_def() to class_pointer_symbol() and use it when a
class name is used as the receiver of a message.

f721144ca5 Rewrite emit_ivars to use emit_structure. 
The old code was broken anyway :) (it was segfaulting).

afc5b2827d 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.
