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

Performance is about the same or slightly better for typical IK chains.
In extreme cases with many bones and multiple targets, of which some are
unreachable, I've seen 2x speedups.
* Rename Legacy to Standard, it's not being deprecated as far as I know.
* Make option to toggle off Location solving work with Standard.
* Make it converge a bit better in some cases by enforcing a minimum number of
iterations before giving up.
* Move IK solver choice out of bone panel, it's an armature level setting and
should be set there.
- comment/remove assignments from values to themselves.
- add case break statements (no functional change but some source code checkers notice).
- fix python errors when the sculpt brush is None.
blender_add_lib now takes a separate include argument to suppress warnings in system includes (mostly ffmpeg & python).
also only build wm_apple.c on apple+carbon configuration.
globbing vs explicit is discussed here.

Practical implications are:
- developers need to keep CMakeLists.txt files up to date.
- Users wont get strange linking errors if they build after a file is added, since CMake detects CMakeLists.txt is modified and automatically reconfigure.
In 2.49, you could adjust the maximum length of Auto-IK Chains by using scrollwheel up/down or page up/down while moving Auto-IK bones. Now this is possible again with those hotkeys, but you need to hold SHIFT to get this to work, otherwise we get a conflict with the hotkeys for proportional edit nowadays.
Was broken when transform tools switched from using hardcoded key mappings to using a modal keymap.
* Division by zero fix for TNT SVD code.
* Sound fix, in case ffmpeg decode fails, don't use the samples.
* Fix for incorrect bounds of transformed objects in new raytracing code.
* Gave memory arena's a name used for allocations for easier memory
usage debugging.
* Dupligroup no_draw option was using layers but not restrict view/render
setting. (not a bugfix exactly but would do display list context switching
while drawing for no reason).
* Fix objects instanced on hair particles not giving consistent results
when the object is transformed.
* New math functions: madd_v4_v4fl, len_squared_v3v3, interp_v4_v4v4v4,
mul_v4_m4v4, SH and form factor functions, box_minmax_bounds_m4.
* mul_m4_m4m4 and mul_m3_m3m3 now accept the same pointers for multiple
arguments.
* endjob callback for WM jobs system.
* Geometry node uv/color layer now has search list/autocomplete.
* Various small buildsystem tweaks, not strictly needed yet in trunk.
- IK-Solver interfaces were still converting units from degrees to radians. Made these all use radians now.
- Tried to fix the DOF limits drawing. This is still not totally functional again yet, but at least there are visible lines now.
