Its only relevant use case has been to use the software renderer on hardware not capable of OpenGL 3.3, but a large chunk of that can now be serviced with GLES.
In addition it has ceased further development and has not received any of the recent 2D render features which further reduces its viability.
* Remove threading from the drawers
* Fix some r_scene_multithreaded related bugs
* Fix some r_scene_multithreaded crashes
* Fix fullbright shade bug
* Fix truecolor drawer crash
* Add debug code for showing the render slices
* Fix texture loading race condition and improve performance by only locking the load mutex if data hasn't already been updated for this frame

With fixed point math barely being used anywhere with the vast majority of calls in the software voxel drawer it makes sense to reduce the function interface to the minimum possible and move the shift value into the function call as an argument.
This included half the game state and lots of unneeded parts of the software renderer.
The two modules that are shared between softpoly and the classic software renderer have been moved to a neutral place.
Aside from using incorrect values this could crash the renderer if used in the very first rendering frame because the software renderer always operates on a copy.
