Cycles: Code style cleanup

Cycles: Fixed Embree Volume rendering when the camera is inside a volume

Cycles: Matched motion interpolation to Embree's interpolation

When Embree is turned on, the transform matrices of motion steps are now interpolated linearly (the wrong way). Cycles itself has a better way of interpolating, but when mixing it with Embree's direct matrix interpolation, it results in artefacts.

Cycles: Fixed a crash when setting up Embree hair curves

Cycles: Fixed wrong Embree line intersections

Line segments should not go through the backfacing test.

Cycles: Set the compact flag on Embree to save memory

Cycles: removed use of constexpr to stay compatible with pre-C++11 compilers

Cycles: Extended Embree integration

Implemented ribbon curves and thick curves for hair.
Embree now obeys the static/dynamic BVH setting.

Cycles: fixed some warnings in embree integration

Cycles: improvements to hair rendering using embree

Cycles: improved defaults for embree option, enable embree in the UI only when a CPU device is selected

Cycles: Added Embree to Unix CMake files

Cycles: Fixed parametric coordinates for hair intersections with Embree

Cycles: embree hair now uses curve and not line segments, no more intersection filters for closest hit queries

Cycles: Added runtime checks for Embree build. If Embree is not configured correctly, it will print warnings to the console.

Cycles: Added support for BVH refitting/dynamic meshes with embree

Cycles: prevented interactive rendering from crashing with Embree when objects are made invisible - RTCScenes now only get deleted by the top level BVH

Cycles: fixed Windows build with Embree

Cycles: fixed Embree transparent shadow ray intersection to terminate properly when opaque objects are hit

Cycles: added memory and progress callbacks to embree
