added basic material handling and outputting vertexgroups for intersect/difference shards with cuttergroups

fix attempt for passive fakeparenting with dynamic/external, and first version of combined cuttergroup and procedural (boolean only) fracture

fixes for constraint behavior in dynamic_external mode

dissolve constraint now only dissolves constraints between different clusters if clusters are used

additionally added a python-settable variable to indicate whether the dynamic fracture data has been loaded externally or not (just set it from the handler)

added handlers which are triggered after freeing shards and before rebuilding constraints

this is supposed to keep externally loaded data in place when changing over to dynamic fracture, the handler triggers a python script which populates the meshislands and another to populate the constraints via the FM python API.
Additionally a couple of minor fixes for dynamic fracturing.

fix for hair particle system, was wrong hair distribution and render error

suppressed "dynamic" particle redistribution for hair now too

fix, forgot to copy splinter axis when duplicating FM object

Merge remote-tracking branch 'refs/remotes/origin/blender-v2.78c-release' into fracture_modifier

tests: Update hash for OBJ

Was a recent update of UV precision.

Cycles: Fix compilation error on 32bit Linux

Fix T50243: libmv_panography_test is broken

There was fully wrong logic in comparison: was actually accessing memory
past the array boundary. Run test manually and the figure seems correct
to me now.

Spotted by @LazyDodo, thanks!

[msvc] Set proper OpenSubdiv flags when not using find_package to find opensubdiv. Fixes T50548

Blender 2.78c: Officially move to 'c'

Cycles: Fix wrong render results with texture limit and half-float textures

Fix T50748: Render Time incorrect when refreshing rendered preview in GPU mode

Fix T50687: Cycles baking time estimate and progress bar doesn't work / progress when baking with high samples

Fix T50512: Linked Backround scene with animation not updating with new depsgraph

Was missing relations for the set scenes.

Perhaps not ideal solution, but should be good enough for now.

Blender 2.78c: Fix crash with material preview and image sequences

Don't use built-in API for image sequences since it's not really
finished in RNA API.

Fixes issue reported in T50616.

Blender 2.78c: Fix wrong render result with pointiness

The issue was caused by pointiness being calculated after
faces split now. Ported all fixes we did here.

Should be safe, pointiness is used all over the barbershop.

Cleanup
