initial C api for geometry sets

cleanup, remove Node::time_stamp

fix after merge

Merge branch 'master' into geometry-nodes

Pointclouds: move blenkernel code to c++

Fluid: Fix strict compiler warning

Proper way to check for DEBUG_PRINT is to do `if defined` check rather
than `if`: this is because in non-debug builds the symbol is not defined.

Cleanup: fix wrong merge, remove extra unique_ptr.

Merge branch 'master' into cycles_procedural_api

Fix T80068: skin modifier not working with motion blur

The skin modifier did not output consistent results, causing failure to find
corresponding vertices across frames.

Remove unnecessary use of GSet, all we need is an array.

Cycles: fix Node::tag_modified not setting modified flag's upper bits

Previous code was flipping the bits on a 32-bit number and doing a zero extension to cast to 64-bit, so mark the constant as long to begin with.

This would also erase previously set bits in this part the flag.

Cycles: Fix function inline attributes

forceinline attribute is only applicable for function which are
marked inline. Interestingly, it can be used for class methods
without explicit inline statement. But for functions it is another
story.

Fluid: Fix strict compiler warning

Proper way to check for DEBUG_PRINT is to do `if defined` check rather
than `if`: this is because in non-debug builds the symbol is not defined.

Merge branch 'master' into outliner-cpp-refactor

Cleanup: Split header for Outliner tree building into C and C++ headers

It's odd to include a C++ header (".hh") in C code, we should avoid that. All
of the Outliner code should be moved to C++, I don't expect this C header to
stay for long.

macOS: follow system preference for natural trackpad scroll direction

And remove Blender preference, which was expected to be set to match the system
preference for correct behavior. Instead just handle this automatically.

Cleanup: Rename Outliner "tree-view" types to "tree-display" & update comments

"View" leads to weird names like `TreeViewViewLayer` and after all they are
specific to what we call a "display mode", so "display" is more appropriate.

Also add, update and correct comments.

Geometry Nodes: rename Geometry type to GeometrySet

This should not change any functionality.

After talking to Brecht, we agreed that it might be good
not to have a class called Geometry for now. In the future
we might want to use a Geometry class as base class for
meshes, curves, etc.

This commit renames the Geometry class to GeometrySet,
because it is essentially a container that can contain
multiple geometries of different types.

Merge branch 'blender-v2.91-release'

Fix T82488: Mantaflow - force fields have very low influence compare to 2.90.1

Removed 0.2f factor when setting forces. Why this factor has been used when forces should only be clamped, nobody knows ..

Geometry Nodes: cleanup Subdivision Surface node inputs
