Separate render and presentation initialization This paves the way for clean initialization of the Vulkan renderer, and very much cleans up the older renderer initialization code as gl and sw are no longer intertwined.

[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).

[vid] Allow render systems to unload late This cleans up the tangled mess of attempting to unload the gl driver in X11: for whatever reason, the display gets tied in to the library.

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] Move frame rendering out a layer. This is a step towards high-level unification of the renderers, as far as possible keeping only actual low-level implementation details in the individual renderers (some higher level stuff, eg shadows, is expected to be per-renderer as some things are just not feasible to implement in all renderers). However, the idea is to move the high-level functionality into scene rendering.

[renderer] Move to using dynamic frame buffers For now, OpenGL and Vulkan renderers are broken as I focused on getting the software renderer working (which was quite tricky to get right). This fixes a couple of issues: the segfault when warping the screen (due to the scene rendering move invalidating the warp buffer), and warp always having 320x200 resolution. There's still the problem of the effect being too subtle at high resolution, but that's just a matter of updating the tables and tweaking the code in D_WarpScreen. Another issue is the Draw functions should probably write directly to the main frame buffer or even one passed in as a parameter. This would remove the need for binding the main buffer at the beginning and end of the frame.

[renderer] Merge the fog support code GL still has its own functions for enabling and disabling fog while rendering, but GLSL doesn't need such (thanks to the shaders), nor will vulkan (and the software renderers don't support fog).
