While SCons building system was serving us really good for ages it's no longer
having much attention by the developers and started to become quite a difficult
task to maintain.
What's even worse -- there started to be quite serious divergence between SCons
and CMake which was only accumulating over the releases now. The fact that none
of the active developers are really using SCons and that our main studio is also
using CMake spotting bugs in the SCons builds became quite a difficult task and
we aren't always spotting them in time.
Meanwhile CMake became really mature building system which is available on every
platform we support and arguably it's also easier and more robust to use.
This commit includes:
- Removal of actual SCons building system
- Removal of SCons git submodule
- Removal of documentation which is stored in the sources and covers SCons
- Tweaks to the buildbot master to stop using SCons submodule
(this change requires deploying to the server)
- Tweaks to the install dependencies script to skip installing or mentioning
SCons building system
- Tweaks to various helper scripts to avoid mention of SCons folders/files
as well

The issue was caused by the following construction:
def = env['SOMETHING']
defs.append('SOMETHING_MORE')
Since first assignment was actually referencing environment option it was totally
polluted hawing weird and wonderful side effects on all other areas of Blender.
The ones in extern/glew-es have been changed to NOTE instead of XXX
GHOST_ContextEGL.cpp: It really does seem that it is not possible to query the swap interval using EGL
GHOST_WidnowCocoa.h: The comment referring to Carbon is clearly out of date, so I removed it.
math_geom.c: The node about not using tmax again is correct, but the code is kept for a future maintainer who will need to know how to compute it if they modify that code.
paint_image_proj.c (2698): The question about integer truncation does not appear to have been resolved. It still seems to be an incorrectly implementation of rounding (I'd suggest using the round function instead of this hack).
