e05c12e16d Make linker_add_def take a pointer for the value.
While it looks like I might not use it for the type encodings, it should be
useful in the future.

5b7b49b100 Add a QFO_TYPE macro to get a qfot_type_t pointer.
In the end, it wasn't used, but it could be handy in the future.

93b007b1f8 Take care of relocs when defining external defs.
For most of the cases, some relocs may have been lost, but they were
certainly lost for type encodings. Now that all seems to be fixed.

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.

d13ce81b4f Ensure the type's encoding string is valid.
When encoding a type to a qfo file, the type's encoding string is written
and thus needs to be valid prior to actually doing the encoding. The
problem occurs mostly in self-referential structs (particularly, obj_class)
because the struct is being encoded prior to the pointer to the struct.

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.

9095e1eabc Rework build_switch to use initialize_def.
This required support for label reference expressions, whose purpose is to
represent the address of a label.

afbab60c25 Create linker_find_def.
It turns out I didn't need it, but it could be useful in the future, so
I'll leave it in.

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.

f8bdd909cc Separate out C and html quoting into separate functions.
Dot sometimes wants normal C quotes, othertimes html. Quite annoying,
really, but this is cleaner anyway.

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).

1364bff91b Add an extended mode to qfcc.
Extended mode allows extra keywords (switch, for, etc) that are compatible
with v6 progs.

e866619de6 Output basic block flow diagrams to files.
The output can be controlled via --block-dot (not yet documented). The
files a named <sourcefile>.<function>.<stage>.dot. Currently, stage will be
one of "initial" (after expression to statement conversion), "thread"
(after jump threading), "dead" (after dead block removal), "final" (final
state before actual code emission).

5f676c367f Add a non-error diagnostic that can't be silenced.
It is inteded for flagging buggy conditions in the compiler, particularly
after having fixed the original bug (in case something comes back from the
dead).

e267e0a664 Allow control of progdefs.h CRC writing.
CRC writing defaults to off for non-v6 progs, but on for v6 progs. The
--progdefs option forces CRC writing.

It's pretty useless in git.

c8163fc0de Add an option to prevent the use of default paths.
Despair has things locked down such that running qfcc during a build fails
due to lack of read access to /usr/local/lib. This is actually a good
thing as accidentally hitting old includes/libs (when a file gets deleted
in the tree) hides bugs. Thus, --no-default-paths to turn off default
search paths.

55cc0f9206 Bring back the unsigned type (PROGS version bump)
This is only low-level support (the unsigned keyword still does not work),
but sufficient to make switch statements using jump tables work.

8d3508cf20 Allocate space for temp defs using size rather than type.
Statement operands throw away the high level type information, so store
type size in the operand and use this size for allocating space for temps
rather than using the low-level type.

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).

02a70ebe1c Remove the auxfunction manipulation from the compiler proper.
It was broken code in the first place (realloc and pointers), and is
redundant with the new linking process.

29cac0fe3a Optionally create *_[xyz] symbols for accessing vector components.
"vector-components" in code options controls this feature. The default is
off for advanced code and on for traditional code. Disabling
vector-components prevents the comonent names polluting the namespace and
reduces the number of globals needed for vector fields if the components
of that field are never used.

4a99f8dcbd Write the linker output to progs.dat.
There is much breakage, but qfcc now produces a progs.dat from either
progs.src or object files. Better yet, the progs.src result is passed
through the linker, removing much duplicate code.
