bbca22c722 [vulkan] Add support for IQM models
Despite the base IQM specification not supporting blend-shapes, I think
IQM will become the basis for QF's generic model representation (at
least for the more advanced renderers). After my experience with .mu
models (KSP) and unity mesh objects (both normal and skinned), and
reviewing the IQM spec, it looks like with the addition of support for
blend-shapes, IQM is actually pretty good.

This is just the preliminary work to get standard IQM models loading in
vulkan (seems to work, along with unloading), and they very basics into
the renderer (most likely not working: not tested yet). The rest of the
renderer seems to be unaffected, though, which is good.

a4f500da3c [vulkan] Add a mini resource subsystem
The resource subsystem creates buffers, images, buffer views and image
views in a single batch operation, using a single memory object to back
all the buffers and images. I had been doing this by hand for a while,
but got tired of jumping through all those vulkan hoops. While it's
still a little tedious to set up the arrays for QFV_CreateResource (and
they need to be kept around for QFV_DestroyResource), it really eases
calculation of memory object size and sub-resource offsets. And
destroying all the objects is just one call to QFV_DestroyResource.

9d7cad420d [vulkan] Add a function to translate QFFormat to VkFormat
It's not great, but it does produce reasonable results for the formats
supported by QF's image system.

419d91edc5 [image] Set texture type for no-load tga images
I might need to do similar for other formats, but i ran into the problem
of the texture type being tex_palette instead of the expected tex_rgba
when pre-(no-)loading a tga image resulting in Vulkan not liking my
attempt at generating mipmaps.

ef6e4722d5 [simd] Add some comments to mat4fquat
Having to refigure out what values are going into the vectors got old
very fast. The comments don't help with verifying the values, but at
least I can tell at a glance where 2(xy - wz) goes and thus determine
the "orientation" of the matrix.

6d62e91ce7 [gamecode] Clean up progs data access
pr_type_t now contains only the one "value" field, and all the access
macros now use their PACKED variant for base access, making access to
larger types more consistent with the smaller types.

f6baa16084 [cvar] Remove the cvar lists
They're really redundant, and removing the next pointer makes for a
slightly smaller cvar struct. Cvar_Select was added to allow finding
lists of matching cvars.

The tab-completion and config saving code was reworked to use the hash
table DO functions. Comments removed since the code was completely
rewritten, but still many thanks to EvilTypeGuy and Fett.

8bd626a3e4 [hash] Add a couple of data-oriented functions
Hash_Select returns a list of elements that match a given criterion
(select callback returning non-0).

Hash_ForEach simply calls a function for every element.

bafe54b010 [view] Add a cexpr enum for grav_t
And use it for hud_scoreboard_gravity. Putting the enum def in view made
the most sense as view does own the base type and the enum is likely to
be by useful for other settings.

9f876390f0 [input] Fix up some mistranslated cvars
My script didn't know what type to make the cvars since they're not used
directly by the code, so they got treated as strings instead of ints or
floats.

12c84046f3 [cvar] Make cvars properly typed
This is an extremely extensive patch as it hits every cvar, and every
usage of the cvars. Cvars no longer store the value they control,
instead, they use a cexpr value object to reference the value and
specify the value's type (currently, a null type is used for strings).
Non-string cvars are passed through cexpr, allowing expressions in the
cvars' settings. Also, cvars have returned to an enhanced version of the
original (id quake) registration scheme.

As a minor benefit, relevant code having direct access to the
cvar-controlled variables is probably a slight optimization as it
removed a pointer dereference, and the variables can be located for data
locality.

The static cvar descriptors are made private as an additional safety
layer, though there's nothing stopping external modification via
Cvar_FindVar (which is needed for adding listeners).

While not used yet (partly due to working out the design), cvars can
have a validation function.

Registering a cvar allows a primary listener (and its data) to be
specified: it will always be called first when the cvar is modified. The
combination of proper listeners and direct access to the controlled
variable greatly simplifies the more complex cvar interactions as much
less null checking is required, and there's no need for one cvar's
callback to call another's.

nq-x11 is known to work at least well enough for the demos. More testing
will come.

d68db74049 [cexpr] Add a flags type
Based on the flags type used in vkparse (difference is the lack of
support for plists). Having this will make supporting named flags in
cvars much easier (though setting up the enum type is a bit of a chore).

392e032ce2 [cexpr] Add a get_string function to exprtype_t
This allows for easy (and safe) printing of cexpr values where the type
supports it. Types that don't support printing would be due to being too
complex or possibly write-only (eg, password strings, when strings are
supported directly).

e40f3f4f93 [model] Make alias skin loading a batch operation
Really, this won't make all that much difference because alias models
with more than one skin are quite rare, and those with animated skin
groups are even rarer. However, for those models that do have more than
one skin, it will allow for reduced allocation overheads, and when
supported (glsl, vulkan, maybe gl), loading all the skins into an array
texture (since all skins are the same size, though external skins may
vary), but that's not implemented yet, this just wraps the old one skin
at a time code.

9892e571ce [vulkan] Move viewport and scissor into qfv_renderpass_t
This makes much more sense as they are intimately tied to the frame
buffer on which a render pass is working. Now, just the window width
and height are stored in vulkan_ctx_t. As a side benefit,
QFV_CreateSwapchain no long references viddef (now just palette and
conview in vulkan_draw.c to go).

11e30583cf [vulkan] Switch to full screen triangle instead of quad
While I have trouble imagining it making that much performance
difference going from 4 verts to 3 for a whopping 2 polygons, or even
from 2 triangles to 1 for each poly, using only indices for the vertices
does remove a lot of code, and better yet, some memory and buffer
allocations... always a good thing.

That said, I guess freeing up a GPU thread for something else could make
a difference.

6bbbe4997b [vulkan] Invalidate mapped capture image memory
I think I had gotten lucky with captures not being corrupt due to them
being much bigger than all but the L3 cache (and then they're over 1/2
the size), so the memory was being automatically invalidated by other
activity. Don't want to trust such luck, though.

790f62a209 [image] Make WritePNG take settings from tex_t
This means that a tex_t object is passed in instead of just raw bytes
and width and height, but it means the texture can specify whether it's
flipped or uses BGR instead of RGB. This fixes the upside down
screenshots for vulkan.

a29836cc2c [quakefs] Return QFile pointer from QFS_NextFile(name)
QFS_NextFilename was renamed to QFS_NextFile to reflect the fact it now
returns a QFile pointer for the newly created file (as well as the
name). This necessitated updating WritePNG to take a file pointer
instead of a file name, with the advantage that WritePNGqfs is no longer
necessary and callers have much more control over the creation of the
file.

This makes QFS_NextFile much more secure against file system race
conditions and attacks (at least in theory). If nothing else, it will
make it more robust in a multi-threaded environment.

a35bfef24c [sys] Add a function to safely create a unique file
QF currently uses unique file names for screenshots and server-side
demos (and remote snapshots), but they're generally useful.
QFS_NextFilename has been filling this role, but it is highly insecure
in its current implementation. This is the first step to taking care of
that.

020ada9fb1 [util] Clean up nested macro temp var names a little
clang doesn't like the same variable name being used in nested

semi-meaningful (based on macro name) tails to keep them separate.

7a6ca0ebcb [simd] Use portable swizzles

495dd759f0 [renderer] Clean up FOV and viewport handling
Viewport and FOV updates are now separate so updating one doesn't cause
recalculations of the other. Also, perspective setup is now done
directly from the tangents of the half angles for fov_x and fov_y making
the renderers independent of fov/aspect mode. I imagine things are a bit
of a mess with view size changes, and especially screen size changes
(not supported yet anyway), and vulkan winds up updating its projection
matrices every frame, but everything that's expected to work does
(vulkan errors out for fisheye or warp due to frame buffer creation not
being supported yet).

3c86764eb2 [scene] Move entity_t etc into scene headers

eventually the renderer will know about only things to render (meshes,
particles, etc).

75d7f4cecb [renderer] Clean up particles a little

3103f400fd [sw] Clean up r_refdef and R_ViewChanged
r_refdef is really meant for holding the various screen "constants" for
the software renderer rather than the more generic scene stuff. All the
fields referenced by the low level rendering code (especially assembly)
have been moved to the beginning of the struct (and nicely fit within 64
bytes). The other fields should be moved elsewhere, but not this commit.

On top of that, R_ViewChanged is much easier to read, and there are
fewer static globals.

a0adca011f [gl] Get fisheye working with frame buffers
Of course, it's not as correct as glsl or sw due to using polygons and
uvs rather than a fragment shader (not that such is out of the question
since GL 3.0 is requested, but I don't feel like getting shaders going
just for a couple of post-processing effects in an obsolete renderer).

f2bc5b560f [renderer] Clean up post processing

286344c7b6 [glsl] Implement fisheye rendering
The code dealing with state is a bit of a mess, but everything is
working nicely. Get around 400fps when all 6 faces need to be rendered
(no surprise: it should be about 1/6 of that for normal rendering). The
messy state handling code did not come as a surprise as I suspected
there were various mistakes in my scene rendering "recipe", and fisheye
highlighted them nicely (I'm sure getting this stuff working in Vulkan
will highlight even more issues).

18aae8205e [glsl] Implement screen warp when in liquids
