3758828d33 Install_deps: update magic build numbers of OIIO and OSL. 
Please remember to change those each time you update building code and there is no version change.
Otherwise poeple re-running the script won't get the updated builds.

e688a62712 Cycles: Fix for initial guess of the radius for Burley BSSRDF 
The value was too high, causing bad Newton iteration step.
Now the value is not so good, but it's still within 9 iterations
and those high number of iterations are only happening in
approx 1% of input values.

3e7389eaf2 Cycles: Speedup of Christensen-Burley SSS falloff function 
The idea is simply to pre-compute fitting and parameterization
in the bssrdf_setup() function and re-use the values in both
sample() and eval().

The only trick is where to store the pre-calculated values and
the answer is inside of ShaderClosure->custom{1,2,3}. There's
no memory bump here because we now simply re-use padding fields
for the pre-calculated values. Similar trick we can do for other
BSDFs.

Seems to give nice speedup up to 7% here on my desktop with
Core i7 CPU, SSE4.1 kernel.

ad26407b52 Cycles: Implement approximate reflectance profiles 
Using this paper:

  http://graphics.pixar.com/library/ApproxBSSRDF/paper.pdf

This model gives less blurry results than the Cubic and Gaussian
we had implemented:

- Cubic: https://developer.blender.org/F279670
- Burley: https://developer.blender.org/F279671

The model is called "Christensen-Burley" in the interface, which
actually should be read as "Physically based" or "Realistic".

87cbcd697b Fix T47266: Blender crashes from Scripted Expression in Driver

are solved (meaning, we don't keep files opened and don't
crash either).

49247f0fc4 Fix T47207: Material shading incorrectly handles colorramp node 
The issue was introduced by a fix for T44713 which only made GLSL
consistent with Cycles.

Now we do have conditional averaging or proper luma weighting based
on whether we're new old old shading system. Not totally ideal but
should work for until we re-design viewport possibly breaking how
Blender Internal does implicit conversion.
