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

eg:
blender -b --python-exit-code 1 --python script.py --render-anim
This causes blender not to continue parsing command line arguments and exit if the script raises an exception.
The issue was caused by a conflict between std::error_code linked into
Blender which is compiled without C++11 support and POCL's expectations
of std::error_code which was actually linked against C++11's STL.
When a user tries to load a non-existing blend file from the CLI, the path
is set and Blender acts as if it is loaded. This allows the user to create
a new file by typing 'blender filename.blend' and then saving. This
behaviour is common in other tooling, such as vim and Mypaint.
Blender's current behaviour (print an error message and open the default
scene) doesn't make much sense. It ignores the filename passed on the CLI,
whereas with this patch that filename is actually remembered, and used when
saving.

- BLI_current_working_dir's return value must be checked, since it may fail.
- BLI_current_working_dir now behaves like getcwd, where a too-small target will return failure.
- avoid buffer overrun with BLI_path_cwd, by taking a maxlen arg.
When using the nmake generator from cmake, numpy fails to extract during build because the working directory doesn't exist yet.

- rename WITH_EXTERNAL_AUDASPACE to WITH_SYSTEM_AUDASPACE.
- rename C/PYAUDASPACE to AUDASPACE_C/PY
- simplifying cmake defines and includes.
- fixing include paths and enabling WITH_SYSTEM_AUDASPACE for windows.
- fixing scons building.
- other minor build system fixes.
Correcting the paths for buildinfo to point to the real header,
ended up breaking buildinfo (by not running every build).
It turns out we relied on the output _never_ existing,
so CMake generates a new buildinfo each time.
This is quite bad, but I didn't see a way for CMake to do this,
so explicitly point to a missing file and comment whats going on.
option.
This makes sense, since contexts get created at runtime, there is little
reason to require recompilation for this.
Only works on linux currently, will be doing more OSs later
For now we work this around by copying python DLL to the
bin folder. Ideally the DLL should be shared between blender
and python, but that's a bit tricky to do on windows.
We had some reports where users did not even read the "Not supported on
release builds" message, and arguably writing a file sort of indicates
that the file may include something useful.
This way it is possible to have single threaded depsgraph but threaded other areas
which is handy for torubleshooting.
