Merge branch 'master' into asset-experiments

Merge branch 'master' into openvdb_smoke

Merge branch 'alembic' into gooseberry

Fix for cycles rendering of shortened hair curves.

The strands data can now contain more vertices than are supposed to be
rendered (if cutoff < numverts).

Get rid of FluidDomainDescription struct.

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.
