Move some files and functions around.

VolumeManager: put OpenVDB related routines in their own functions.

Don't construct default samplers, rather just store pointers to
accessors and transforms.

Fix segault when closing Blender.

The cache was freed after the smoke domain...

Avoid recalculating the object's data when a new cache is added.

Fix for cache not being set as current when deleting the first in the
list.

Merge branch 'master' into openvdb_smoke

Cleanup: indent

Move source/blender/openvdb folder to intern/openvdb

Cycles: style cleanup.

Cycles: rename OpenVDBManager -> VolumeManager, et simili.

Implementation of VDB ray intersectors.

They are not used yet though.

Cycles: subclass the grid samplers and make them thread-safe.

Thread-safety wasn't a requirement before but as they are now thread-
safe, they use ValueAccessors for faster sampling.

Fix typos in smoke exporter.

Expose file compression types.

By default files are compressed based on their active values, with zip
compression optionnaly added to it. We can as an option, enable blosc
compression, through a build flags. This flag is only to be enbaled if
OpenVDB was built with blosc. Otherwise -> crash.

Merge branch 'alembic' into gooseberry

Conflicts:
source/blender/blenkernel/BKE_key.h
source/blender/blenkernel/intern/key.c
source/blender/bmesh/intern/bmesh_strands_conv.c

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).
