Merge branch 'alembic' into gooseberry

Conflicts:

Support for cutoff parameters in Alembic files.

These are optional, so older alembic cache versions still work.

Take transformation of the duplicator object into accound for hair
cutting.

When using a dupli object from the same group as a target it is
sufficient to calculate the relative transform in the shared duplicator
local space. When using an external object though we have to transform
into world space first.

Fix for incorrect cutoff points with the haircut cache modifier.

Implemented hair cutting for cached strands, based on a cutoff parameter
for child hairs.

The algorithm works by finding the first intersection of each child
hair with the target mesh. The child hairs have to be deformed with
their parents first (this usually happens *after* modifiers).

Clean keyframes:

Keep handles as they were (cleanup code could ever slightly tweak
animation handles, which was not so good)

Merge branch 'master' into gooseberry

Conflicts:
source/blender/windowmanager/intern/wm_playanim.c

Option for the haircut cache modifier to either use a scene object or
an "internal" object from the group.

Initialize curve mappings once after creating, just to be sure.

New cache modifier "Haircut", for removing unwanted child hairs.

Alembic: Update stubs file so building without alembic works fine

Initialize the VDB writer when creating a new cache.

A new function to split a vector grid into three scalar grids.

Move fluid matrices to SmokeDomainSettings.

A new function to create a sparse vector grid from three scalar dense
grids.

Redesign the VDB API a bit.

dynamic fracture: now multiple dynamic objects can exist, need to test interaction with prefractured, though

SCons: Hopefully fix for gooseberry branch compilation

Use a flag to explicitly apply shape keys to either the goal positions
or the motion state.

Use correct blending weights for hair shapekey references.
