[renderer] Clean up entity_t to a certain extent This is the first step towards component-based entities. There's still some transform-related stuff in the struct that needs to be moved, but it's all entirely client related (rather than renderer) and will probably go into a "client" component. Also, the current components are directly included structs rather than references as I didn't want to deal with the object management at this stage. As part of the process (because transforms use simd) this also starts the process of moving QF to using simd for vectors and matrices. There's now a mess of simd and sisd code mixed together, but it works surprisingly well together.

[sw] Make alight_t lightvec an actual vector The change to using separate per-model-type entity queues resulted in the lighting vector used for alias and iqm models being in an ephemeral location (in the shared setup_lighting function's stack frame). This resulted in the model rendering code getting a garbage vector due to it being overwritten by another stack frame. What I don't get is why the garbage varied from run to run for the same demo (demo2, the first scrag behind the start door showed the bad lighting nicely), which made tracking down the offending commit (and thus the code) rather troublesome, though once I found it, it was a bit of a face-palm moment.

[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.

[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).

It takes advantage of the ECS in that the edge renderer needs only the world matrix, brush model pointer, and the animation frame number (which is just 0/1 for brush models), thus the inherent SOA of ECS helps out, though benchmarking is needed to see if it made any real difference. With this, all 4 renderers are working again.

[renderer] Abandon sw32 altogether I'd been considering it for a while, but in the end, all the issues it presented made me decide it wasn't worth merging and was never really worth keeping: it was a neat proof of concept but of little actual use, especially now everyone either has an OK GPU or would want to stick to 8-bit rendering anyway (sorry L-Havoc). However, both it and my merge work are preserved in git history :)

Nuke qboolean from orbit I never liked it, but with C2x coming out, it's best to handle bools properly. I haven't gone through all the uses of int as bool (I'll leave that for fixing when I encounter them), but this gets QF working with both c2x (really, gnu2x because of raw strings).

[renderer] Support multiple entity queues While there's currently only the one still, this will allow the entities to be multiply queued for multi-pass rendering (eg, shadows). As the avoidance of putting an entity in the same queue more than once relies on the entity id, all entities now come from the scene (which is stored in cl_world in the client code for nq and qw), thus the extensive changes in the clients.

[model] Move plane info into mnode_t, and visframe out The main goal was to get visframe out of mnode_t to make it thread-safe (each thread can have its own visframe array), but moving the plane info into mnode_t made for better data access patters when traversing the bsp tree as the plane is right there with the child indices. Nicely, the size of mnode_t is the same as before (64 bytes due to alignment), with 4 bytes wasted. Performance-wise, there seems to be very little difference. Maybe slightly slower. The unfortunate thing about the change is the plane distance is negated, possibly leading to some confusion, particularly since the box and sphere culling functions were affected. However, this is so point-plane distance calculations can be done with a single 4d dot product.
