Merge branch 'blender2.8' into hair_guides

Revert "Add a hair system to particles to eventually replace the current pathcaches."

This reverts commit 3ba96b7c4da8aa3461db5985b8d5c762695d49e2.

Comment on return value.

More detailed API for partially updating hair export caches.

This will allow proper caching of draw data as well as optimization
of GPU buffer uploads when only guide curve deform changes.

Add a hair system to particles to eventually replace the current pathcaches.

Modifier copy function uses const now.

Remove the simple hair guide generator, can test through the API now.

Fix indexing of vertex buffers for Cycles hair.

Render support for hair systems in Cycles.

Also cache guide tangents and normals and fiber root positions in export data.

New HairExportCache struct to unify pre-computation of hair data for OpenGL, render, and eventual data export.

Cycles: split off particle data gathering into separate function.

The general particle caching "Obtain" functions can be used for any
curve-type data in objects, including the new hair system data.

Fix changed signature of applyModifier callback.

Depsgraph update after changing guide curves through the fur modifier.

Make sure hair follicle binding is updated before using invalid indices in drawing.
