Add upstream information to libraries

Code refactor: minor node and node type utility functions and changes.

Collada: Adding support for bone roll and bone layers

Differential Revision: https://developer.blender.org/D2034

Add BLI_array_store copy-on-write API

This supported in-memory de-duplication,
useful to avoid in-efficient memory use when storing multiple, similar arrays.

Depsgraph: Fix missing updates when modifying armature

Fix T48447: Inactive menu items don't grey-out icons

3D Text: Use BLI_array_store for undo storage

Cleanup: remove unused doxy config

Fix T48434: Missing meta support in new depsgraph

CMake: Workaround to get Libmv compiled with latest Gcc

Cleanup: fix inconsitency in dynamicPaint_outputLayerExists()

Dyna WPaint indeed only uses first output layer, but better be consistent in those cases...

Code refactor: pass ShaderInput to constant_fold, so it supports arbitrary types.

Dynapaint: Serious cleanup and optimization of dynamicPaint_createUVSurface (mostly).

Gives 3-4% speedup in pre-bake step (from 112 to 108 seconds with own heavy test file).

Note that here we have a huge potential performance boost if we replace the flat
`Bounds2D *faceBB` array of UV tris bounding boxes by a real 2D AABB tree (right now,
we can loop over all UV triangles times the number of pixels of the surface times 5...).

EditNormal modifier: add some 'maximum angle' limit.

Allows to avoid generating flipped faces when using extreme normal modifications.

Related to T48576.

Code refactor: make ShaderNode match Node a bit more, reusing types and enums.

Support Cycles magic texture in GLSL viewport

Cycles: Fix wrong closure counter in feature adaptive kernel

Some closures were missing from calculation, leading to an array
under-allocation, presumable causing memory corruption issues with
emission shaders on OpenCL and was causing issues with Volume 3D
textures with CUDA.

The issue was identified by Thomas Dinges, the patch is different
from the original D2006. See the brief discussion there. Current
approach is similar (or the same) as Brecht suggested.

Cleanup: warning

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

Makefile: Use hidden FORCE target
