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.

Neither Nuke nor Natron support OpenCV's radial distortion model
which makes it impossible to have any kind of interoperability.
The new model is available under the distortion model menu in Lens
settings.

Done also in 2.83 release branch to avoid too much conflicts on merging
(some of those were already done for nodes in master, and gave me
conflicts yesterday...).
During scene copy modifier mask strips are relinked to point to strips in
new scene. If strip used as mask is in different seqbase, this can fail,
if seqbase is not copied yet.
Add SEQ_DUPE_IS_RECURSIVE_CALL flag to avoid relinking modifiers during recursive call.

This hides the original metaballs when they are used in
duplifaces/-verts instancing, and still shows the instanced metaballs.
The visibility of the original metaballs is now determined by the
visibility of the instancer. I'm not too thrilled about this, but at
least it gives users the ability to show/hide the metaballs for
viewport/render.

The main use-case for the Track To constraint is camera tracking, so
this sets up a better default for this. That is, track to -Z with Y up.
Agreed on internally with Pablo Vazquez and William Reynish. Should
there be a reason to revert this, that would be fine compatibility-wise.
The old Subdivide button was behaving as if subdivision modifier was
applied on top of the multires. This was the source of shrinkage since
the behavior of the limit surface: limit surface of a sparse point
from another limit surface makes final result appear smaller.
The new behavior is based on propagating delta against base mesh's
limit surface to the top level. Effectively, this is as if we've
sculpted on old top level and then propagated to the new top level.

This fix the issue by introducing a default material only for collection
holdouts. This avoids hash colision when the same material is used in
collections without holdout enabled.
This is a regression introduced in rBa0fe22095e6d9b8b194c2cf6f9a7c7b419d7e61c.
I changed it so that the velocity with the highest magnitude is considered and
not the highest value per coordinate.

Own error in cleanup from 5dcb6fb22f unintentionally
changed enum values. Although this code violated our own
rules to use explicit values to avoid this happening.
Using MAX2 when writing intial velocities into the grid prevents overriding initial velocities when using multiple flow objects that are close to each other.
When using the 'Replay' cache mode the cache needs to be invalidated whenever simulation variables have been changed.
The invalidation will always only affect the according subcaches, e.g. when changing a mesh paramter only the mesh cache will be invalidated, the base cache will remain intact.
Before this change Blender always invalidated the entire cache.

There is no user visible difference in standard builds, as there are no
volume modifiers yet. When using WITH_NEW_OBJECT_TYPES some deform only
modifiers are now available for hair and pointcloud objects.
