fix the persistent fires. For sanity's sake, the non-renderer specific parts of gl_dyn_fires.c have been moved to r_main.c (for now).

[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.

sw and gl rmisc are now client clean. the graphing functions ahve been pulled out into r_graph.c (Time and Z graph), cl_ngraph.c (Net graph), and {gl,sw}_graph.c (R_LineGraph). gl_ngraph.c is gone. Unfortunatly, something is rather wrong with NetGraph in gl (probably R_LineGraph).

Call R_SetFrustum in all renderers. It turns out glsl, sw and sw32 weren't getting any benefit from R_CullBox because the frustum wasn't setup :P. Get another 8% out of bigass1 (174->184fps). bigass1 now runs 2x as fast as it did before I started this optimisation run :)

[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.
