2020-05-20	Cleanup: make guarded memory allocation always thread safe	Brecht Van Lommel
	Previously this would be enabled when threads were used, but threads are now basically always in use so there is no point. Further, this is only needed for guarded allocation with --debug-memory which is not performance critical.
2020-05-14	Fix: Broken build with TBB disabled.	Ray Molenkamp
	Lite builds without TBB and still needs the alternative codepath
2020-05-14	Fix T76553: Blender Freezes When Playing Back Animation	Jeroen Bakker
	In some cases blender could freeze. When threads are blocked (waiting for other tasks completion) the scheduler can let the thread perform a different task. If this task wants a write-lock for something that was read-locked in the stack a dead lock will happen. For task pools every task is isolated. For range tasks the inner loop will be isolated. The implementation is limited as isolation in TBB uses functors which are tricky to add to a C API. We decided to start with a simple and adapt were we need to. During testing we came to this setup as it was reliable (we weren't able to let it freeze or crash) and didn't had noticeable performance impact.

2020-05-09	Fix T76427: edit mesh undo hanges when building without TBB	Brecht Van Lommel
	Background task pools would not restart threads if reused multiple times, thanks to Jeroen for identifying the cause of this problem. Differential Revision: https://developer.blender.org/D7659

2020-05-05	Tasks: support build with TBB version 2017	Brecht Van Lommel
	Make the task pool implementation compatible with older versions that are used by install_deps.sh.

2020-04-30	Task: Use TBB as Task Scheduler	Brecht Van Lommel
	This patch enables TBB as the default task scheduler. TBB stands for Threading Building Blocks and is developed by Intel. The library contains several threading patters. This patch maps blenders BLI_task_* function to their counterpart. After this patch we can add more patterns. A promising one is TBB:graph that can be used for depsgraph, draw manager and compositor. Performance changes depends on the actual hardware. It was tested on different hardwares from laptops to workstations and we didn't detected any downgrade of the performance. * Linux Xeon E5-2699 v4 got FPS boost from 12 to 17 using Spring's 04_010_A.anim.blend. * AMD Ryzen Threadripper 2990WX 32-Core Animation playback goes from 9.5-10.5 FPS to 13.0-14.0 FPS on Agent 327 , 10_03_B.anim.blend.
