Cycles: do not consider level set grids.

Cleanup: deduplicate check to see if a given grid exists in the file.

Cleanup: warning.

Cleanup: magic number.

Support for drawing the grid values in the viewport.

Fix for own commit: cycles volume slots are not the same as the index
in the openvdb grids array.

Fix for undefined density slot when using OpenVDB nodes without
connecting the density socket.

The density grid is used for the primary intersection tests, so it needs
to be identified among others. The slot index used before was not
initialized when the density node socket is not connected. Further and
invalid index (-1) is not recognized and leads to buffer underrun.

Fix for missing boost dependency when OpenVDB is disabled.

Fix compilation error when WITH_OPENVDB is off (again).

OpenVDB has a dependency on boost-iostreams lib.

Blender needs to link this for static OpenVDB libraries.

Fix for bad level function implementation.

Was declared in BKE, but implemented in editors, giving undefined
references in the player.

Gooseberry: Fix compilation error with OpenVDB disabled

Initial support for drawing the VDB tree in the viewport.

To make it possible an OpenVDBPrimitive onject is introduced which hides
a shared pointer to an openvdb::GridBase so it's a bit generic, but by
far not final.

The drawing code is a bit hackish on the side, but at least it works and
here's an example: http://www.pasteall.org/pic/show.php?id=89278

NOTE: This only works when the simulation is imported back in.

Move exported flag from SmokeDomainSettings to OpenVDBCache

Merge branch 'master' into openvdb

OpenVDB: Disable it for blenderplayer buildbot target

OpenVDB: Tweaksfor scons and buildbot

Fix typo in writefile.c resulting in undefined nodes.

Generalized node function for mapping existing inputs/outputs on a
dynamically changing socket layout.

This is used for a couple of nodes which create a custom set of inputs
or outputs based on internal data (e.g. image or cache files with
arbitrary data layers). The task is to take existing connections to the
node and relink them to the new socket layout, usually based on socket
names. This keeps node trees working as much as possible even when the
user changes the node.

Multilayer image nodes were already doing this, now OpenVDB shader nodes
can share the same function. If it can be represented in the RNA, the
OSL script node might use the same method (currently not feasible due
to callbacks).

More flexible feedback function for reading header and metadata from
OpenVDB files.

Instead of fixed-size arrays (risking overrun) the function now uses a
callback, which allows callers to store the info in their own data
structures as needed. Nodes use this to create a list of grid info
structs and adding node sockets accordingly.
