Fix for merged 'normal map tangents not working correctly when there are no UV maps.'

Merge branch 'master' into blender2.8

Fix T51950: Abnormally long Cycles OpenCL GPU render times with certain panoramic camera settings

The problem here was that when a "invalid" path is generated by the panoramic camera, it was tagged
as RAY_TO_REGENERATE with the intention of generating a new path in kernel_buffer_update.

However, since that state was not handled in kernel_queue_enqueue, kernel_buffer_update did not
process the path which resulted in an infinite loop.

Cycles: Add missing split kernel to CPUDevice

Fix T51523: Lattice modifier affecting particles even when disabled

Particles were ignoring the lattice modifier visibility, and
"influence" property.

Eevee: Hide lightprobe data when using "Only Render"

Fixed build error on Windows / VS2015

Alembic: fix T51820 for sequence files not loading properly.

Alembic: avoid crashing when doing certain file operations.

Things like missing directories are now properly checked for, rather than
crashing Blender.

This also adds support for relative paths when opening an ABC file.

Alembic: renamed offset ? sequence_offset

Fix T51883: Wrong matrix computation in "Make Duplicates Real"

Fix T51963: Eevee: ASAN crash on copy_attrib_name

Fix T51951: cell noise texture precision issue at unit vertex coordinates.

Solution is to bias the coordinates a little, same as Cycles checker texture.
