a296b8f694 GPU: replace GLEW with libepoxy
With libepoxy we can choose between EGL and GLX at runtime, as well as
dynamically open EGL and GLX libraries without linking to them.

This will make it possible to build with Wayland, EGL, GLVND support while
still running on systems that only have X11, GLX and libGL. It also paves
the way for headless rendering through EGL.

libepoxy is a new library dependency, and is included in the precompiled
libraries. GLEW is no longer a dependency, and WITH_SYSTEM_GLEW was removed.

Includes contributions by Brecht Van Lommel, Ray Molenkamp, Campbell Barton
and Sergey Sharybin.

c434782e3a File headers: SPDX License migration
Use a shorter/simpler license convention, stops the header taking so
much space.

Follow the SPDX license specification: https://spdx.org/licenses

- C/C++/objc/objc++
- Python
- Shell Scripts
- CMake, GNUmakefile

While most of the source tree has been included

- `./extern/` was left out.
- `./intern/cycles` & `./intern/atomic` are also excluded because they
  use different header conventions.

doc/license/SPDX-license-identifiers.txt has been added to list SPDX all
used identifiers.

See P2788 for the script that automated these edits.

47adab4f99 CMake: prepare for BLENDER_SORTED_LIBS removal
No functional change, this adds LIB definition and args to cmake files.
Without this it's difficult to migrate away from 'BLENDER_SORTED_LIBS'
since there are many platforms/configurations that could break when
changing linking order.

Manually add and enable WITHOUT_SORTED_LIBS to try building
without sorted libs (currently fails since all variables are empty).
This check will eventually be removed.

See T46725.

ef640ecf10 OpenGL: remove use of GLEW MX
MX (Multiple conteXt) support was dropped from the GLEW 2.0 library to make core profile support cleaner.

Our WITH_GLEW_MX build option was OFF by default already; this commit removes the inactive code paths.

I'm working on a plan for multiple GPUs, contexts, resource sharing, etc. This commit gives us a cleaner starting point for that upcoming work.

Tested on Mac, will test on Linux & Windows immediately after pushing.

5d99cde822 Remove SCons building system
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

dfc672f8bb SCons: Fix for really nasty bug with polluting configuration environment
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.

88fe896243 Checked each of my (jwilkins) XXX notes.
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).
