Cycles: new Microfacet-based Hair BSDF with elliptical cross-section support

Not sure why this was 4 before, there are only 2 closures, ...HairBSDF and ...HairExtra.

Cycles: new Microfacet-based Hair BSDF with elliptical cross-section support

These are utitily functions for matching direct color with absorption coefficient. They are designed for Principled Hair BSDF, and don't seem to match very well with the Microfacet Hair BSDF. Currently I just "borrow" these functions so direct coloring is also available for the new model. I could move the three shared functions to bsdf_util.h, or duplicate them in bsdf_hair_microfacet.h, if this matters.

Cycles: new Microfacet-based Hair BSDF with elliptical cross-section support

The curve normal (which is needed for orienting the cross-section) is not considered in the legacy hair curve. I don't want to put too much effort into this if the legacy curve is to be discarded at some point.

Cycles: add instancing support in light tree

Thanks for the patch. The two proposed alternatives require the same amount of memory (16 bytes more compared to the version with union), but with variant the intention of the code is clearer…
