Multithreaded implementation can provide significant performance gain
on CPU's that can handle more parallel tasks.
On my 8 core system I got about 3.5x faster processing speed.

Original sequence lookup failed, becase name changed in another thread.
Fix is same as 0471349c90df - stop prefetching before changing content
of seqbase.
I have covered more cases, and added assert so it is more obvious that
issue is in lookup, and it shouldn't fail.

The BLI_bitmap had the potential to eat a lot of memory as it was a
dense map between all the vertices in the mesh.
Now we instead use BLI_edgeset so that we only store data when needed
(creating a spare map instead of a dense).
Allows to hook per-space code which is to be run on view navigation.
This is required to have zoom-to-fit implemented in the sequencer.
There might be more cases where the clalback is to be called from,
but it could be easier to address those on the case-by-case basis
when its needed.
It was impossible for drivers to use shape key properties, modifiers
generate a new mesh. After mesh evaluation the shape keys are no longer
necessary, and because of this the `key` pointer was not copied. As
drivers work on evaluated data, however, they do need this `key`
pointer.
This commit makes the `key` pointer available in evaluated meshes, but
this is somewhat dangerous. There was an explicit reason why the key on
result was kept at null pointer: to have the evaluated mesh in a
consistent state. Assigning this pointer makes it potentially
inconsistent, as the evaluated mesh and the original shape key may have
different topologies.

This was a regression in deaff945d0 which skips copying a mesh.
Dupli-verts/faces were not updated to account for this.
This supports iterating over edit-mesh vertices & faces,
since falling back to a full copy (as we do in some places)
will be slow while transforming geometry.
This commit looks as if it would change behavior with orcos,
since any edit-mesh deformation causes them to be assigned.
However in practice there is no functional change, details in comments.
Replace the evaluated mesh with VertexDupliData.mvert since only
vertices are used. This makes dupli-vert similar to how dupli-face
was already working.
This adds the boundary_falloff_type and boundary_offset to control how the
falloff of the Boundary Brush is applied.
Boundary Origin Offset is the same concept as the Pose Origin offset in
the Pose Brush. It is a multiplier that adds extra length to the brush
radius to locate the deformation pivot further from the boundary without
affecting the falloff.
The Falloff type includes Constant (previous default), brush radius, loop
and loop and invert. Loop and Loop and Invert can be used to create
deformation patterns in a mesh.

This brush deletes displacement information of the Multires Modifier,
resetting the mesh to the subdivision limit surface.
This can be use to easily delete parts of the sculpt or to fix
reprojection artifacts after applying a shrinkwrap.

This is particular important because 2.90 will coexist with 2.83 LTS, so
we should warn the users of potential loss of data when going from 2.90
to 2.83 and back.
