Depsgraph: Tag all id_types on_visible_update

We need all id nodes to be evaluated at least once when opening a file.
This is particuarly required for the upcoming group collection patch.

Merge branch 'master' into blender2.8

Haiku OS Support

Even though Haiku is a niche OS, only minor changes are needed.

Cycles: Improve denoising speed on GPUs with small tile sizes

Previously, the NLM kernels would be launched once per offset with one thread per pixel.
However, with the smaller tile sizes that are now feasible, there wasn't enough work to fully occupy GPUs which results in a significant slowdown.

Therefore, the kernels are now launched in a single call that handles all offsets at once.
This has two downsides: Memory accesses to accumulating buffers are now atomic, and more importantly, the temporary memory now has to be allocated for every shift at once, increasing the required memory.
On the other hand, of course, the smaller tiles significantly reduce the size of the memory.

The main bottleneck right now is the construction of the transformation - there is nothing to be parallelized there, one thread per pixel is the maximum.
I tried to parallelize the SVD implementation by storing the matrix in shared memory and launching one block per pixel, but that wasn't really going anywhere.

To make the new code somewhat readable, the handling of rectangular regions was cleaned up a bit and commented, it should be easier to understand what's going on now.
Also, some variables have been renamed to make the difference between buffer width and stride more apparent, in addition to some general style cleanup.

Fix T53410: 3D Text always recalculated

GP Build Modifier - Layer Masking support

Fix: Menu with various extra operators for active palette color was missing

Cycles: Fix rendering of barbershop scene

Cycles: Removed scaling from Embree's object motion blur.

Cycles native drops scaling from motion interpolation, the scale of the center of the frame gets reused to all motion positions. Embree could interpolate scaling too, but mixing the two then causes trouble with secondary rays, as Cycles does its own transformation interpolation in the intersection refinement. For now, restrict Embree to the common denominator, hopefully soon we can reintroduce scaling motion blur to Cycles.

Fix T53420: Vertex Groups: The "-" button gets a hidden function

Guess 'remove all unlocked' is new-ish feature...

To be backported to 2.79a (I think).

Cycles: add object level holdout property.

This works the same as the holdout shader and Z mask layer. Combined with
overrides in 2.8 this is intended to replace the Z mask layer bits.

Cycles: improve triangle intersection performance.

Reduces render time by about 1-2% in benchmark scenes.
