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

Fix own mistake in D1120: wrong indexing of UV maps during tangent calculation

Fix T48508: Cycles Regression / Crash

Fix T48496: Viewer function in NodeWrangler addon don't work in Material Shading mode

Cleanup: indentation

Fix T48486: Not enough precision in Volume Sampling Step Size input

Volumes might be small, makes sense to use more precision here.

GHOST cleanup (null check before delete, and 0 -> NULL for pointers).

Based on patch from Lawrence D'Oliveiro (ldo) in T48499.

Forgot this in previous commit

Add upstream information to libraries

Sequencer's histogram view: OMP -> BLI_task.

New code using loop/finalize model is about 45% faster (from 4.4ms tp 2.4ms per frame,
overall playback of single shot in sequencer in this preview mode goes from 40 to 45fps).

ndof: build system cleanup

Only Linux needs a lib linked in (libspnav).

ghostndof3dconnexion refers to an obsolete Mac driver shim.

ndof: enable Linux support by default, unless libs missing

Cycles CUDA: reduce stack memory by reusing ShaderData.

57% less for path and 48% less for branched path.

Fix T48487: Physics cache names allow (back)slashes, which breaks its handling.

For now, just validate new pointcache names as if they were filnames.

Ideal solution would be rather to validate names in `ptcache_filename()`, but it would
likely break some existing caches - and we'd also have to ensure we still have
uniqueness of name after it has been cleaned up, wich would not be trivial at this stage.

So let's go for simple solution for now, especially since this part of code is to be
fully rewritten in 2.8...

Enable correct GLSL output for cycles normalmap node
