Cycles: More consolidation for deferred ray marching

Cycles: Deferred ray marching now correctly spearates multiple intersections with the same object

Cycles: Fixed bug where deferred ray marching would always march to infinity

Cycles: Fixed a mistake in my previous volume change - deferred ray marching would count multiple intersections of the same volume incorrectly.

Cycles: adding provisions to prevent volume stack overflow, don't add the same volume object twice even when there's empty space in between

Cycles: fixed BV-5 - state update on volume bounce was overwriting bounce index and caused early path termination

Cycles: Fixed an issue with deferred ray marching where it wouldn't update the volume stack properly for volume scattering.

Cycles: Small fix for deferred ray marching.

OpenVDB: speedup.

Cycles: add bump map shadow terminator softening term for diffuse BSDFs

This avoids artifacts for bump mapping and diffuse BSDFs, where the bump
normal deviates far from the actual normal.

Cycles: Added feature override to render diffuse surfaces only.

This leaves emission, transparency and volumes intact but replaces
all other surface shading with gray diffuse.
