fix: Import of meshes with holes is now reported as WARNING (unsupported)

Image viewer scopes update: OMP->BLI_task.

Gives over 50% faster scope update (from 4.5ms to 2.2ms here with SD shot)!
Probably mostly due to more clever usage of thread-local data (which avoids any lock,
when OMP code had a rather stupid critical section for minmax)...

Correct invalid pointer-pair compare check

Cleanup: glsl style

BMesh: don't alloc zero sized select elem array

Fix T48514: Cycles toon glossy BSDF not respecting reflective caustics option.

Cycles CUDA: reduce branched path stack memory by sharing indirect ShaderData.

Saves about 15% for the branched path kernel.

Fix T47257: bevel crash when there are internal faces.

Bevel had assumed that when rebuilding a face that touches
a vertex with beveled edges, the edges of the face at that vertex
would be adjacent in internal order. That is not necessarily true
if there are edges with more than two faces attached.
We could just prohibit beveling any edges that touch a vertex
where this happens (we already don't bevel non-manifold edges)
but the use case in the model of T47257 seems reasonable.
Also had to fix the edge-ordering code, and the face reconstruction
code to take care of cases where the face normal may not be as expected.

Depsgraph: Simplify some loops using foreach()

Add warning to Mesh.from_pydata

Depsgraph: Solve wrong datamask calculated by depsgraph

This is a weak concept, but nice t support it for now, so we can enable
new depsgraph by default earlier.

Cycles: Yet another fix for textures limit

Move editmesh undo into its own file

Cycles: Fix wrong cuda textures limits

Cycles: Fix wrong render results when using multiple OpenCL devices
