Paste flipped bones:

* Simplify logic for bone detection on copy (no need to do mirrored
naming then)
* Add shortcuts ctrl(cmd)-shift-V for copying flipped

Separate context freeing from task freeing in threaded particle updates
to prevent double-freeing/invalid mem access.

This can happen with the "virtual parents" feature, which generates both
parent and child paths. Each task free function also freed the shared
context, leading to double freeing.

Use the interpolation direction of the hair flow for integrating
hair strands.

Depsgraph: Drivers on armature-obdata were getting added twice, causing redundant errors to be printed

Depsgraph: Editing various todo notes

Gradient calculation and normalization from the pressure field.

Solver for the pressure Poisson equation on hair flow grids.

Note: does not include boundary conditions so far.

Depsgraph: For now, knock out RNAPathKey connection when creating drivers

This doesn't actually do anything yet, since the lookups usually end up pointing
to structs which cannot be located in the graph. Currently, we manually
set up links for the common situations where this would be useful, so it should
be fine to disable this for now. Plus, it silences a whole bunch of warning
prints.

Depsgraph: Animated shapekeys update properly now

Gooseberry animation request: Paste flipped pose in action
and graph editor.

This was a tricky commit that was not so straightforward to make work.
The information for bones is not easy to come by in the animation curves,
however we do have some string manipulation tricks to make it happen.
For now committing to gooseberry branch for testing, it will be ported
to master after most usual use cases have been confirmed as working.

(Current test with all rotation modes and translation seems to work, but
Not sure how well this will hold up with drivers etc)

Add moving around bookmarks (same system as for vgroups etc.).

First step toward hair directional flow solving: Calculate divergence
from "source" (emitter) meshes.

Depsgraph: Fix crash when built with legacy depsgraph and transforming the object

Simply forgot to add return into a function which shouldn't be used with new dependency graph.

Depsgraph: use command-line switch to legacy depsgraph

This is because of couple of reasons:

- It should be able to switch to legacy depsgraph to back up the production.
- It's not really reliable to switch dependency graphs on runtime. It might
always be some missing update or so. Plus keeping two dependency graphs
up to date is slower.

To use legacy depsgraph run blender with --debug-depsgraph command line arg.
