Fix T79309: Safe Areas are not visible

Merge branch 'blender-v2.90-release' into master

Fix T79575: Crash loading nested set-scenes

Merge branch 'blender-v2.90-release' into master

Python: include Python stack trace in the crash log

This helps Python developers troubleshoot errors when
Python causes a crash.

Cleanup: use doxy sections for py_capi_utils.c

Cleanup: no need for plural for term 'collision'

Sculpt: Cloth Brush/Filter Collisions

This implements collisions in the solver of the cloth brush/filter. It
uses the scene colliders as a regular physics simulation.

There are still some parameters (friction, distance to the surface...)
that can be exposed as properties in later patches.

Thanks to Sebastian Parborg for helping me with the implementation.

Fix T78698: Move cursor stuck after removing modifier

The panels are rebuilt when a modifier is removed so the button handlers need
to properly finish. By adding a context argument to the panel_delete function
this will happen properly.

Sculpt: Sharpen Mesh Filter curvature smoothing and intensify details

This adds a curvature smoothing and intensify details properties to control
the result of the Sharpen Mesh Filter.

Curvature smoothing removes high frequency details from the precalculated
sharpen data, so the filter result has much smoother surfaces and cleaner
sharpen lines;

Intensify details displaces the vertices of creases and valleys in the direction
opposite to its neighbors average, so it intensifies high frequency details
in those areas, producing more noisy and sharp shapes:

Both this properties can be used in combination to achieve a good balance of
high and low frequency details depending on the shape and the desired result.

Fix Squash and Stretch naming in the Pose Brush deform mode

Previusly it was using the / character, which implies that there is one
deformation mode and and invert deformation mode like in the other two
deformation, but squash and stretch is only one deformation mode and
does not have an invert mode.

Sculpt: Option to lock the rotation in the Pose Brush scale deform mode

The scale deform mode includes rotation by default, so when when scaling
down a part of the models it becomes harder to control as the effect of
the rotation less predictable (similar to using trackball rotation in a
very small radius). This locks the rotation of the segment, so parts of
the model can be scaled down in a more predictable way.

Fix T78954 EEVEE: Motion Blur: Bug with hair particles on linked objects

The cache key for particle system was the original Object data. But this
is incorrect for particle systems as modifiers are not shared.

Fix file name sometimes not visible immediately after renaming

Steps to reproduce were:
* Open File Browser
* Create a new directory
* Cancel renaming with Esc

File selection flags were modified during drawing when the rename button
got removed, but the file name label drawing wasn't checking the
modified state.
