Cleanup: Rename func occurences to _fn

Use _fn as a suffix for callbacks.

USD Import: material blend bug.

Fixed bug setting the material blend mode due
to an uninitialized variable.

Fix crash with pinned geometry node tree with no active object

The check for a null active object was after trying to retrieve the active
modifier from the object.

Cleanup: Use blender::Vector.

Fix: compilation OpenCL kernels Compositor.

Animation: add function to apply a pose from an Action

Add `BKE_pose_apply_action(object, action, anim_eval_context)` function
and expose in RNA as `Pose.apply_action(action, evaluation_time)`.

This makes it possible to do the following:

- Have a rig in pose mode.
- Select a subset of the bones.
- Have some Action loaded that contains the pose you want to apply.
- Run `C.object.pose.apply_pose_from_action(D.actions['PoseName'])`
- The selected bones are now posed as determined by the Action.

Just like Blender's current pose library, having no bones selected acts
the same as having all bones selected.

Fix wrong samples stop criteria in Cycles path trace

With multiple samples scheduled at once the stop criteria needs to be
adjusted.

On a first glance seemed like things will be much faster, but no: the
way how scheduling worked was just requesting 0 samples for many loop
iterations. Still stupid but does not cause that measurable of speedup.

Cycles: add megakernel for new integrator, to finish last path faster

Also always used for CPU since it's a bit faster.
