GPencil: Fix unreported problem when main Onion switch is disabled

The main switch was not checked and the function was doing all calculations, but the data was not used. This makes all slower than expected because the user had the Onion Skinning disabled, but internally was running.

Cleanup: expand tabs

Cleanup: missing break & shadowing warnings

Removed debug .obj file outputs

Sculpt: Mesh Filter Tool

The mesh filter tool applies a deformation to all vertices in the mesh at the same time. It includes multiple deformation modes and the option to lock the deformation axis.
This commit also includes the FilterCache, which is needed in some new operators and tools.

Sculpt: Elastic Deform Brush

This patch implements the paper "Regularized Kelvinlets: Sculpting Brushes based on Fundamental Solutions of Elasticity" https://graphics.pixar.com/library/Kelvinlets/paper.pdf

It includes grab, biscale grab, triscale grab, scale and twist.
All deformation modes are accessible under the same tool. This helps to keep the code organized and it should not make any difference to the user when a better brush management system is implemented.

Fix T69663: 2.81 Cant open/append/link a blend file but 2.8 can

Was a problem in the versioning code from rBbaaa89a0bc54, since the
TexMapping struct could already be freed and node->storage could already
be set to NULL (if a file with the new mapping node [saved from (2, 81,
8) or newer] is opened in a blender version prior to (2, 81, 8) and
saved from there again).

DNA: initial DNA defaults support

This provides an API to access structs
with their members set to default values:

- DNA_struct_default_get(name)
- DNA_struct_default_alloc(name)

Currently this is only used for scene & view shading initialization,
eventually it can be used for RNA defaults and initializing
DNA struct members on file reading.

GPencil: Change Arrange Strokes menu order

Before: Bring Forward, Send Backward, Bring to Front, Send to Back.

After: Bring to Front, Bring Forward, Send Backward, Send to Back.

Sculpt: Draw Sharp Brush

This brush is similar to the draw brush but it deforms the mesh from the original coordinates. When used with the sharper curve presets it has a much more pleasant crease/cut behavior than any of the other brushes. This is useful for creating cloth wrinkles, stylized hair or hard surface edges.
