[renderer] Pass in a camera transform More r_data cleanup. Things could be better still, but this is a start.

[renderer] Merge screenshot code as much as possible Only CaptureBGR is per-renderer as the rest of the screenshot code uses it to do the actual capture (which is target dependent). Vulkan is currently broken due to capture being an asynchronous process and the rest of the code expecting capture to be synchronous (also, bgr vs rgb). The best thing is all renderers now write the same format (currently png).

Change hudswap to use a callback, and instead of passing a swap variable to 10 functions, where only 2 use it, use a global variable. Make a few scr functions static inline, too. Got a totally unexpected ~0.45fps speedup.

typedef void (*SCR_Func)(void);
[renderer] Continue the job of merging SCR_UpdateScreen I think this is probably as merged as it will get (though the update callbacks can probably do with some merging).

void SCR_UpdateScreen (struct transform_s *camera, double realtime,
SCR_Func *scr_funcs);
[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).

void SCR_SetFOV (float fov);
[renderer] Clean up a lot of recalc_refdef use I think the widespread use of recalc_refdef (and force_fullscreen) was the result of a rushed merge of the renderer and video code (I do seem to remember sprinkling them around). This cleans the two out of the client code.

[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.
