As class objects don't have retain counts (they're usually static, even!!),
allowing the instance implementations of retain, release, and autorelease
attempt to modify the non-existant retainCount would be a recipe for severe
headaches. We also don't want the retainCount returning "random" values.
Going by "standard" Objective-C, retainCount really doesn't belong in
Object itself. The way GNUStep does it is to stash retainCount in memory
just below the object by allocating extra bytes for the count and returning
a pointer just beyond those extra bytes. Now Ruamoko does the same. This
fixes the inconsistencies in structure layouts for Protocol and class
structs between qfcc generated (internal) structs and user visible structs.
Structures (especially hard-coded ones) can be really nasty as they can
refer to themselves. Avoid the recursion by setting the type_def field of
the type before doing the recursive encodings in the structure encoder.
The encodings of static types were getting corrupted because their defs
were not necessarily in the same places between compilations when compiling
multiple files.
The result of parse_params needs to be passed through find_type before
actually being used. I guess I'd missed this back when I got things working
for qc.
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).
The attached patch (against quakeforge git) changes the [con]width,
[con]height, and most importantly the rowbytes members of viddef_t
from unsigned to signed int, like in q2. This allows for a properly
negative vid.rowbytes which may be needed in, e.g. a DIB sections
windows driver if needed. Along with it, I changed a few places
where unsigned int is used along with comparisons against the relevant
vid.* members.
One thing I am not 100% sure is the signedness requirements of
d_zrowbytes and d_zwidth: q2 has them as unsigned but I am not sure
whether that is because they are needed as unsigned or it was just an
oversight of the id developers. They do look like they should be OK
as signed int to me, though: comments?

Note from Bill Currie: I had to do some extra changes as many
signed/unsigned comparisons were somehow missed.
This fixes the horribly different results between optimized and unoptimized
qfbsp (there is still a difference of 1 brushface). Unfortunately, it also
severely limits the maximum size of a map.
smart leak files now produce many points, not just one per portal. Normal
leak files now center the trail on the portal (instead of some weird
weighted average).
There is no error checking, texture alignment or support for non-point
lights, but it's a start. Also, it's assumed all brushes are convex and
manifold.
It turns out the expected orientation of the sky cube is exactly that of
Blender's default cube looked at from the front view (num-1) and the front
face being the nearest face. This put's Marcher's sun nicely in the view
when exiting the cave.
Rearrange the sky_suffix and sky_coords arrays and remove the sky_target
array such that the faces can be loaded using
GL_TEXTURE_CUBE_MAP_POSITIVE_X + i (apparently certain drivers break if
the faces aren't loaded in the correct order).
Also, the nomalization of the direction vector in the fragment isn't
necessary.
