`BKE_sequencer_prefetch_get_original_sequence()` didn't look in metas
and returned NULL. This caused crash in disk cache that was trying to
read seq->name.
Add function that will look in meta strips recursively and condition
that seq must not be NULL.

Previously there were two functions for FCurve extrapolation, one for
before the first keyframe, and the other for after the last. After the
previous cleanup made the variable names consistent, it was clear that
the code was almost identical. The biggest difference was in the sign of
many of the calculations, which was cancelled out by swapping `B-A` to
`A-B`. This showed that the computations are actually the same, and the
only remaining difference was which neighbouring handle to use in case
of Bézier curves.
No functional changes.

Variables have been renamed so that they refer to the endpoint and its
neighbor (rather than `bezt`, `prevbezt`, or `lastbezt`), and
unnecessary variables have been removed. By returning early the code
flow is also easier to understand.
No functional changes.
The `fcurve_eval_keyframes` consists of three parts:
- Before the first keyframe
- After the last keyframe
- Between the keyframes
This commit splits the first two parts into separate functions. This is
the first of a series of refactors, which will be committed into smaller
parts so that each is easier to follow & validate.
No functional changes.
All the driver-specific code in `fcurve.c` has been moved into a new file
`fcurve_driver.c`. The corresponding declarations have been moved from
`BKE_fcurve.h` to `BKE_fcurve_driver.h`.
All the `#include "BKE_fcurve.h"` statements have been investigated and
replaced with `BKE_fcurve_driver.h` where necessary.

This is to improve the case of T71055 where curves share the same batch
cache when they shouldn't.
This however, does not help to fix edit mode display.
The real fix would be to have a similar handling to what the mesh modifiers
do and duplicate the whole Curve data. But this is too much work/change for
the 2.83 release.

This introduces two alternative subdivision modes that generates
displacement on the grids that look as Simple subdivisions but while
using the Catmull-Clark subdivision type in the modifier. This way,
Simple and Catmull-Clark subdivision can be combined when creating new
levels if needed, for example, to sculpt hard surface objects.
Subdivide simple smooths the sculpted data when creating a new
subdivision level. Subdivide linear also preserves the sharpness
in the sculpted data.

This implements the main unsubdivide algorithm which rebuilds a base mesh and extracts the grid's data from a high resolution mesh.
It includes the Rebuild Subdivisions operator, which generates all subdivision levels down to the level 0 base mesh.
It supports:
- Rebuilding an arbitrary number of levels (Unsubdivide) or as many levels as possible down to level 0 in a single step (Rebuild Subdivisions).
- Rebuilding with already existing grids.
- Meshes with n-gons and triangles
- Meshes with more than 2 faces per edge
- Base mesh made completely out of triangles
- Meshes without poles
- Meshes with multiple disconnected elements at the same subdivision level

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.

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.

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
