BGE: python API cleanup - replace BLI_program_path with BKE_appdir_program_path

Depsgraph: Fixes for drivers with bone targets defined using RNA Paths

Now, these drivers don't get blocked waiting for the bone evals to finish.
This makes them function better (specifically, allowing them to have some
of the same benefits as they did in the old depsgraph)

Depsgraph: Stub in a few more relations to ob transforms to go along with geometry when doing parenting

Depsgraph: Bone constraints depending on the armature transforms were not working

Code cleanup: Remove redundant comment

Depsgraph: Code cleanup for single operation components

If a component has just a single operation and no declared entry/exit operation,
get_entry/exit_operation() now automatically just uses the operation that does
exist.

Depsgraph: Add support for a few more common datatypes to pointer_to_component_node_criteria()

This is used by the RNAPathKey lookups, so supporting more types of data here should
ensure more node lookups to work successfully.

Spiral kink mode for particles.

This is BAD code, but the particle kinking does not make it easy to
write a non-local modifier that requires neighboring positions,
curvature, etc. The feature is needed for Gooseberry.

Merge branch 'master' into asset-experiments

Reorganization:
* Make 'clear preview' a C operator;
* Move 'object preview generator' op in wm namespace;
* Add those two to file-> data preview submenu.

Reorganization: move ID filters to DNA_ID.h, and add helpers in bke's idcode.c to convert between idcode and idfilter.

Optional clumping noise feature for simulating twisted hair strands.

This adds another level of clumping on child hairs. When enabled, child
hairs chose a secondary clumping target using a Voronoi pattern. This
adds visual detail on a smaller scale, which is useful particularly when
the number of parents is relatively small.

Natural fibres behave in a similar way when they become sticky and
intertwined. Hairs close to each other form a first twisted strand, then
combine into larger strands. Similar features can be found in ropes:

Disable scope updates in texture and image paint modes.

Scope update is very slow for high resolutions, and currently blocks
the UI thread(!). This is especially terrible in paint modes, where
each stroke causes a scope update and unacceptable freezing.

The scopes update method tries to avoid this somewhat by skipping if the
toolbar is disabled, but this doesn't help when painting where brush
tools etc. are frequently needed. It's also a bad-level poll, with the
core system accessing a UI element.

Eventually scope updates should become a low-priority background job,
as well as becoming threaded. Until then this polling provides a usable
workaround to the most outrageous cases.

Depsgraph: Fix for using bones as targets for hook modifier

The hook modifier now depends on the bone component of the relevant bone
instead of the entire pose result. This makes it possible to interleave
relationships where different bones in the same armature depend on the hooked
geometry.

Depsgraph: Fill in missing depsgraphUpdate callback for new modifier
