Cycles: Fixes for regular BVH since previous commit

Merge branch 'master' into soc-2016-multiview

Cycles: Switch node address to absolute values in BVH tree

This seems to be straightforward way to support heterogeneous nodes
in the same tree.

There is some penalty related on 4gig limit of the address space now,
but here are the things:

- Traversal code was already using ints to store final offset, so
there can't be regressions really.

- We know that node size is 16 bytes aligned, so we use SHR/SHL magic
to increase address space of nodes still.

This is a required commit to make it possible to encode both aligned
and unaligned nodes in the same array. Also, in the future we can use
this to get rid of __leaf_nodes array (which is a bit tricky to do since
trickery in pack_instances().

Cleaup: de-duplicate exception safety code.

Add velocites for liquid meshes to the OPolyMeshSchema sample by
default, instead of using a arbitray property.

Curves: Extend curve operator

Implements the "get_intersections" function, which calculates intersections between straigth lines and Bezier curves.

Cycles: Commit heuristics and builders from hair branch

Not currently in use, will be hooked up to existing code shortly.

This commit also contains some traversal helpers, but those are also
not in real use.

Cleanup: comments.

Merge branch 'master' into cycles_bvh

Add support for reading normals.

Also rewrite the normals write code, and add utility functions for Y-up
<-> Z-up conversion.

Implemented "real" hiding of UV elements

Previously it wasn't possible to hide elements without altering the BMesh selection state

ToDo: Make UV operators ignore hidden elements

update autotrack two-view reconstrution

WIP experimental support of direct image-as-linkeddata.

Works okish, but break on load (or save) of .blend file currently...

Cycles: Some more comments

Cycles: Fix crash rendering mesh with hair

First step towards supporting non-blender-data as assets.

Idea is to avoid the need for asset engines to generate whole .blend files
with relevant datablocks in case they just need/want to provide files (images, videos, sounds...).

This commit introduces the concept of 'virtual' library, which in fact only exists to store
asset repository data. Datablocks from those virtual libs are then fully written in .blend file.

Much to do still, this is only preliminary/experimental work.

Cycles: Some comments

Cycles: Optimize aligned triangle storage a bit

The idea is to keep triangle storage aligned with the BVH traversal code.

This gives couple of percent speedup comparing to previous version and
reduces overall slowdown (which is now 4% on the barcelona file here on
own desktop, and half of it is caused by the inner BVH node visibility
commit),
