Removed unused old code.

Disable the path length check for spiral kink mode.

This test is terribly expensive for some reason and not necessary for
for the spiral mode anyway.

Fix for calculation of the key velocity on the last child hair segment.

Another crappy approach to spirals on hairs, crazy expensive though.

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.

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.

Curve-based control for "roughness" (noise displacement) of child hair.

Merge branch 'hair_clumping' into gooseberry

Curve-based control for child path tapering.

This is an alternative method to the current fixed function with a
clump factor and "shape" parameter. This function is quite limited and
does not give the desired result in many cases (e.g. long, parallel
rasta strands are problematic). So rather than trying to add more
parameters there is now a fully user-defined optional curve for setting
the tapering shape.

Moved kink, clump and roughness functions into the dedicated source file.

Reorganizing hair child code a little bit to make it not totally insane.

This contains a few pieces of code for a future "modifier" system that
would allow more flexible combination of effects. Eventually a node
system is the way to go, but the current code makes that impossible.

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.

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)
