Attribute interpolation for ngons

Copy ptex faces to device memory

Kernel now has access to ptex faces and ptex face mapping

Store ptex offset for faces

Each ngon is split into multiple faces, need to keep track of how they relate.

Split ngons into quads

Replace Patch with SubdFace with inital ngon support

This renames most mentions of patches to subd faces, old way of naming was
confusing. Also start supporting ngons, which will be needed for proper
Catmull-Clark subdivision surfaces. Right now this is mostly just changing
how data is passed around, actual ngon support will come later.

Simplify how primitive counts are passed to Attribute

Refactor Attribute so that primitives counts don't need to be passed around
everywhere and can be calculated from one place.

Remove extra image texture from kernel_textures.h

Rename BKE_cachefiles_open_next_file to BKE_cachefile_update_frame.

Fix for opening files using relative path during .blend file loading.

Temporary quick hack for compatibility

When reading an old .blend, all objects of it are simply moved to a new layer of the new system. In future this can be resolved better though.

Merge remote-tracking branch 'origin/master' into soc-2016-uv_tools

Merge branch 'master' into soc-2016-layer_manager

Added object nodes for looking up an object and transform from global data.

Use a str hash for the hierarchy map.

Cleanup: move ExportSettings to abc_exporter.h.

Cleanup: export options.

LLVM TypeBuilder and copy function for node_counted_ptr.

Using a DerivedMesh directly for mesh data isn't so great because
the lifetime of a DM is not necessarily known at compile time, depending
on branching. node_counted_ptr is basically a simplified shared_ptr variant.

Use a hash table to register external functions with the LLVM engine.

This will allow using BLI/BKE code for complex data types, such as DerivedMesh.

Include mesh opcode functions in modules.

Modifier functions with variable expression inputs are disabled,
until DerivedMesh handling through LLVM is implemented.

Moved map creation into the toggle.
