These functions no longer accept NULL. They were renamed for clarity and to
avoid hidden merge issues.

CUDA is working correct without it now, and it's more efficient not to do this.

This never really worked as it was supposed to. The main goal of this is to
turn noise from sampling tiny hairs into multiple layers of transparency that
do not need to be sampled stochastically. However the implementation of this
worked by randomly discarding hair intersections in BVH traversal, which
defeats the purpose.
If it ever comes back, it's best implemented outside the kernel as a preprocess
that changes hair radius before BVH building. This would also make it work with
Embree, where it's not supported now. But it's not so clear anymore that with
many AA samples and GPU rendering this feature is as helpful as it once was for
CPU raytracers with few AA samples.
The benefit of removing this feature is improved hair ray tracing performance,
tested on NVIDIA Titan Xp:
bmw27: +0.37%
classroom: +0.26%
fishy_cat: -7.36%
koro: -12.98%
pabellon: -0.12%

Apply clang format as proposed in T53211.

Note this is not supported, there exists no geometry at this point, but
it should not crash at least.

I wouldn't mind changing style to have space after keyword, but there was
no official code style change proposed.

This means the shader can now be used for procedural texturing. New
settings on the node are Samples, Inside, Local Only and Distance.
