0293167bd2 [util] Get simd tests working for emulated simd
A bit of a mess for optimized vs unoptimized, but the tests acknowledge
the differences in precision while checking that the code produces the
right results allowing for that precision.

ef9b04ba83 [util] Get tests working with sse2
It seems that i686 code generation is all over the place reguarding sse2
vs fp, with the resulting differences in carried precision. I'm not sure
I'm happy with the situation, but at least it's being tested to a
certain extent. Not sure if this broke basic (no sse) i686 tests.

778c07e91f [util] Get vectors working for non-SSE archs
GCC does a fairly nice job of producing code for vector types when the
hardware doesn't support SIMD, but it seems to break certain math
optimization rules due to excess precision (?). Still, it works well
enough for the core engine, but may not be well suited to the tools.
However, so far, only qfvis uses vector types (and it's not tested yet),
and tools should probably be used on suitable machines anyway (not
forces, of course).

a461c09586 [util] Make cmem consistent on 32 and 64 bit systems
I don't know that the cache line size is 64 bytes on 32 bit systems, but
it should be ok to assume that 64-byte alignment behaves well on systems
with smaller cache lines so long as they are powers of two. This does
mean there is some waste on 32-bit systems, but it should be fairly
minimal (32 bytes per memblock, which manages page sized regions).

1cf40be484 [vulkan] Create shadow maps and basic data
I will definitely need to look into sparse images later (2.3GB for
marcher) but the shadow map images, views and matrices are created.

562f3c2fe2 [vulkan] Add tan and cos perspective projection
The tan and cos versions allow specifying the fov directly from the tan
or cos of the half angle, useful for dealing with lights.

d5454faeb7 [gamecode] Set legacy progs def sizes from type
Legacy progs do not have the extended defs data (and usually won't have
anything more complicated than a vector), so use the basic type size for
the def size. Fixes broken edict prints.

ae231319ea [vulkan] Implement all the extended light models
Standard quake has just linear, but the modding community added inverse,
inverse-square (raw and offset (1/(r^2+1)), infinite (sun), and
ambient (minlight). Other than the lack of shadows, marcher now looks
really good.

52168da93e [vulkan] Don't lose other sky cube faces
Because LoadImage uses Hunk_TempAlloc, the face images need to be copied
individually. Really, what's neeeded is to be able to load the image
data into a pre-allocated buffer (ideally, the staging buffer for
vulkan, but that's for later).

dc9b64fadd [vulkan] Clean up image barriers a bit
Mostly, this gets the stage flags in with the barrier, but also adds a
couple more barrier templates. It should make for slightly less verbose
code, and one less opportunity for error (mismatched barrier/stages).

8c03ed8be5 [vulkan] Start work on shadows
This gets the shaders needed for creating shadow maps, and the changes
to the lighting pipeline for binding the shadow maps, but no generation
or reading is done yet. It feels like parts of various systems are
getting a little big for their britches and I need to do an audit of
various things.

c29e9828b6 [vulkan] Clean up misuse of va for vulkan handles
The built up "path" name of the handle resource was not always surviving
the intervening call to cexpr_eval_string (in particular, when other
handles were created in the process of creating a handle). Rather than
simply increase the number of va buffers (where would it end?), just
regenerate the path when adding the new handle. It's probably quick
enough, and the code is not usually not on a critical path.

da39bb2df3 [vulkan] Use more correct dependency flags
I was reading about multi-pass rendering on mobile devices
(https://developer.oculus.com/blog/loads-stores-passes-and-advanced-gpu-pipelines/)
and discovered that I had used the wrong flags (but then, I think Graham
Sellers had, too, since used his Vulkan Programming Guide as a
reference). Doesn't seem to make any difference on desktop, but as
there's no loss there, but potential gains on mobile, I'd say it's a
win.

1e9329ccf6 [nq,qw] Stop wring to config.cfg
QF now uses its own configuration file (quakeforge.cfg for now) rather
than overwriting config.cfg so that people trying out QF in their normal
quake installs don't trash their config.cfg for other quake clients. If
quakeforge.cfg is present, all other config files are ignored except
that quake.rc is scanned for a startdemos command and that is executed.

9a2f82bbc6 [util] Add big-endian short msg read/write
And improve the generated code for MSG_ReadShort

I suspect gcc didn't like all the excess pointer dereferences and so
couldn't assume that the bytes were being read sequentially.

Bill Currie
afd7b38551 [util] Add big-endian long msg read/write
And improve the generated code as well (ie, use a code sequence that gcc
recognizes and optimizes to a single 32-bit read and a byte-swap).

nq uses big-endian for its packet headers (arg, though it is consistent
with IP, it's not with the rest of quake).

e2f545eb23 [vulkan] Wait on device idle before deleting models
This fixes the textures (and presumably mesh data) being deleted while
still in use. Oddly, the wait was needed in both brush and alias models
(I expected brush to always come first).

39103cc8a3 [sw] Fix some 32-bit assembly issues
I'm not sure that the mismatch between refdef_t and the assembly defines
was a problem (many fields unused), but the main problem was due to
execute permission on the pages: one chunk of asm was in the data
section, and the patched code was not marked as being executable (due to
such a thing not existing when quake was written).

37be6a23a2 [entity] Use _aligned_malloc etc for _WIN32
This is a bit of a hack for now (need to look into maybe using cmem),
but it gets 32-bit windows working for all but the software renderer
(probably just refdef (and maybe viddef) getting out of sync with the
assembly code.

612eb49d9c [render] Separate fov x and y calculations
This ensures that fov_y is not calculated until after the render view
size is known and thus doesn't become some crazy angle (that happens to
result in a negative tan). Fixes upside-down-quake :)

37d35811e3 [vid,render] Clean up fov and aspect
vid.aspect is removed (for now) as it was not really the right idea (I
really didn't know what I was doing at the time). Nicely, this *almost*
fixes the fov bug on fresh installs: the view is now properly
upside-down rather than just flipped vertically (ie, it's now rotated
180 degrees).

55d3193b5f [vid] Set pixel format for OpenGL
This gets the GL and GLSL renderers working for the -win targets... sort
of: they are upside down and GLSL's bsp surfaces are black (same as
Vulkan). However, with this, all 5 renderers at least limp along for
-win, 4/5 work for -sdl.
