Fix incorrect RNA function parameter flags

unittest touch ups

render_layer.collections.link/unlink()

Cycles: Implement split kernel for CUDA

Helpful to have another device to test against and check that the split
kernel remains compatible with all devices.

fix for external FM mode, take object locations into account as centroids for physics shapes, too

Make 3D View scene data syncing work with window level scenes.

We previously updated all screens - visible or not - when changing scene layers or scene camera. Now we only update visible ones and ensure a screen is updated when activating it. This simplifies things a bit and makes it possible to update 3D Views directly through notifiers.

particle system: allow changing vgroups over time, suppress emission on empty assigned density vgroups

fix attempt for avoiding unintentional dissolve of all constraints in dynamic fracture

fix : inner vertexgroups created with fractal boolean now too

unittest: new layer, layer_collection_link/unlink

Fixup for rna_SceneCollection_remove

Debug UI revamp

unittest: syncing when unlinking a collection

Syncing: update layercollection tree when an object is unlinked

Note: filtering is not implemented/fully considered yet

unittest: make tests more granular

Layers: unittest to cover unlinking of objects

Syncing: an object added to a scenecollection

Also changed the ObjectBase->refcount logic a bit, to simplify
further implementations of syncing.

Syncing: update layercollection tree when a new scenecollection is added

Cycles: Rename and add new matrix math helper functions to clean up the actual filter code
