Cycles: Split kernel_path_lamp_emission

Cycles: Split indirect_lamp_emission

Cycles: Only use first lamp in indirect_lamp_emission

Produces different results when lamps overlap from POV of a ray, but allows
for this function to be split. The differences probably wont be noticeable
in most scenes. Old behavior could be reattained by placing lamps
into the BVH.

Cycles: Fix mistake with ShaderEvalTask that could lead to crash

Cycles: Merge shadow_blocked_ao and _dl kernels to improve build times

Gives another 4 seconds improvement.

Cycles: Remove early out that may cause threads to diverge before barrier

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 Embree Volume rendering when the camera is inside a volume

Cycles: Fixed a crash when setting up Embree hair curves

Cycles: Code style cleanup

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.

updated caching (now using frame 1 for liquids as well) and also added new snd particle parameters

Cycles: Fixed parametric coordinates for hair intersections with Embree

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

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

Cycles: Added Embree to Unix CMake files

Cycles: fixed Windows build with Embree
