Windows: Remove zero terminator from stack trace

Important lesson to be learned here, leaving comments
is great and in the moment, they usually make sense.

Many months later they may not quite make as much sense
any more and time will have to be spend to figure out
what was meant, all of this would have been averted with a
better comment.

The zero terminator in this case, I can find no evidence
of it being used or relied on at any point. It does however
break GTests's `EXPECT_EXIT` macro that stops looking in
the output as soon as it sees the zts and doesn't end up
looking at the actual assert text being thrown. Which in
turn makes the`fcurve_active_keyframe`test fail when run
in debug mode on windows.

Cycles: modernize usage of rna iterators

Using rna iterators in range-based for loops is possible since {rBc4286ddb095d32714c9d5f10751a14f5871b3844}.

This patch only updates the places that are easy to update
without more changes in surrounding code.

Fix build error after Cycles Amembic procedural commit

Cycles: internal support for Alembic procedurals

The implementation is currently optimized to load animation sequences once
and then quickly scrubbing through them. Later on an option should be added
to optimize for memory usage and only load the current frame into memory.

Currently mesh and curve objects are supported, including support for UV and
vertex color attributes. Missing still is support for arbitrary attributes and
motion blur, as well as better handling of changing topology. Shader assignments
are made using FaceSets found in the Alembic archive.

The animation (and constant) data of the objects inside the Alembic archive is
loaded at once at the beginning of the render and kept inside a cache. At each
frame change we simply update the right socket of the corresponding Cycles node
if the data is animated. This allows for fast playback in the viewport
(depending on the scene size and compute power).

Note this is not yet exposed in the Blender UI, it's a feature that is still under
development and not ready for general use.

Cycles: internal support for the concept of procedurals

Procedurals are nodes in the scene that can generate an arbitrary number of
other nodes at render time. This will be used to implement an Alembic procedural
that can load an Alembic file into Cycles nodes. In the future we also expect to
have a USD procedural.

Direct loading of such files at render time is a standard feature in other
production renderers. Reasons to support this are memory usage and performance,
delayed loading of heavy scene data until rendering, Cycles standalone rendering
using standard file formats beyond our XML files, and shared functionality for
Cycles integration in multiple 3D apps.

LibOverride: refactor of relationships handling in library overrides.

First step towards a better handling of relationships between IDs in
override context, especially when a resync is needed.

First, introduce a new flag to override operations,
`IDOVERRIDE_LIBRARY_FLAG_IDPOINTER_MATCH_REFERENCE`, for ID pointers.
It keeps track of whether an RNA ID pointer has been kept to its
'natural overriden ID' (in override hierarchy context), or has actually
been re-assigned to some other data-block.

Second, refactor how we deal with relationships between IDs in override
hierarchy code, especially in resync case. This will fixe several cases
listed in T83811, especially the case where an ID pointer to an existing
override needs to be updated to a new one due to a matching change in
linked data.

Fix T85027: Crash dragging a collection over empty Outliner

Filtering may make the Outliner tree empty. The function to find the drop
element should just return null then and let the caller decide how to deal with
it.

Fix T84964: Crash when running Knife Project in the background

Although the Knife Project operator converts 3D coordinates to screen

Cleanup: Knife Tool: Remove redundant 'view3d_operator_needs_opengl' calls

This function sets the `RegionView3D` matrices to the GPU.
But the OpenGL library is not actually being used by the operator.

UI: improve categorization in Grease Pencil Layers sub-panels

The "Layers" panel for Grease Pencil objects uses sub-panels to organize
their properties in categories. Currently, this isn't so clear.
This patch cleans up these sub-panels with clearer categorization.

Fix T84324: Crash when combining two scenes in compositor.

In the CompositorOperation::deinitExecution the viewer could be freed at
the same time it was drawn in the image editor or node editor. There is
a guard for that but wasn't added during the migration of the two
editors to the draw manager.

Buildbot: Fixed crash when building RC builds
