This was a nasty bug which was caused by specific of how face-edge
attributes are stored in Carve.
Face pointer is used in the map key which works just fine in all
cases except for the cases when some face is getting freed after
it was stored in the map.
This might give real issues when new face is allocating because
it's possible new face would have the same address as the freed
one.
Such cases used to happen when union of separate manifolds is
needed for the operands AND jemalloc is enabled.
Solved by dropping attributes for the freed faces from the map.
Maybe not the fastest ever approach, but not sure how to make
it faster actually. Should work just fine. It only happens for
complex setups with intersecting manifolds in the operands.
The variables are considered invalid unless DM_update_materials is
called prior to use. Only use case currently is
mesh drawing. This helps with excessive allocation on the stack during
GPUObject creation, but may help elsewhere in the future as well.
-ffast-math is evil, not sure why it was enabled...
I seems to work better on OSX but it's still not a good idea.
The SConscript for bullet is a mess, I don't understand why
we use different flags for different platforms in the first place.
Seems to be a historical artifact but I don't know enough about scons
to try and clean it up.
This fixes the ptaxs "ACCESS_VIOLATION" error and should allow our Linux and Windows build bots to compile again.
Unfortunately this comes with a performance penalty on sm_2x cards, so this is only a workaround for now. Branched Path is still globally disabled on GPU.
Issue here was that buttons_texture_context_compute() was getting scene from (button-customized) context,
before the button paths (and hence, context) had been updated. So after an undo, it was getting an invalid
(freed by undo) scene pointer.
Now update BCONTEXT_SCENE path before calling buttons_texture_context_compute().
There is no good solution here, since RNA props can only have one type/unit.
Tried to find the less worse one - have different RNA props for same DNA value
(a bit like the angle/length for camera lens).
Also fixed two other issues with Transform conctraint:
* Angle were still in degrees (yes, another backward-compatibility breacking).
* Scale was absolute, unlike loc/rot.
Also cleaned up a bit the code, replaced some magic numbers by proper enums, ...
This required BL_ArmatureObject to have tighter control over armatures and poses.
Also, (Blender) armature objects are now copied instead of shared between
BL_ArmatureObjects to avoid race conditions. Also, due to the armature copy,
shape key drivers need a bit of extra fiddling to get the correct armature copy.
Initially OpenMP was used for threading, but then BLI_task was used due to being
less compiler dependent.
This commit also places time spent on skinning updates in the Animation
profiler category (was previously under the Rasterizer category).
Doubts: are written as comments in the code
Current Problems:
- stereo modes sometimes have different names and are ordered differently everywhere (blender properties panel names and tooltips, blenderplayer cmndline)
- dome mode as several options, but can only take one at a time, like -D mode bla -D tilt X -D ...
- gameoptions are also given one at a time, like above, but with an assignment -g option = X . This is inconsistent.
- gameoptions need to be reviewed and docummented
- parent to window (-i) is useful for what? (there is no wiki on this either)
- there is no support for verbose options like --help (blender itself supports it)

See T39470 and D436. Code by @tippisum, with some minor edits by @mont29.
Tested with various rigs, including Rigify, CGcookie flex rig, and gooseberry/pataz caterpillar.
Riggers, please test it, no change expected in behaviour.

Issue is, looks like Debian testing's graphic backend now uses LLVM-3.4,
which conflicts with 3.3 in Blender and makes it crash.
So add support to handle 3.4, by both allowing to force a specific version for some libs,
and switching back to head of official repo for OSL.
