Depsgraph: Fix typo in assert

Blender 2.8: Apparently auto-merge worked incorrect in the merge commit

Merge branch 'master' into blender2.8

Depsgraph: Link from material to object shading

This is a ground work for the upcoming changes in Blender 2.8 branch
where we need to do special actions to reconstruct shaders when
material changes.

Depsgraph: Add relation from node tree to material it's coming from

Depsgraph: Remove owner argument from relations builder as well

The idea was to link something to a parent, but the point is:
we must not pass owner deep and then have any parent-type-related
logic implemented in the "children".

Fix (unreported) crash when file browser attempts to show preview of some defective font

Confirmed with the Wine's bundled fonts.

Depsgraph: Remove owner node argument which was simply passed around

Compositor: Make HSV node inputs a real sockets

This is much more flexible solution which will allow doing some
more procedural features.

Fix unfreed memory after cleaning render layers

The freestyle data was never freed when removing a renderlayer.

```
blender -b --factory-startup --debug-memory --python-expr "import bpy;bpy.ops.scene.render_layer_add();bpy.context.scene.render.layers.active_index=0;bpy.ops.scene.render_layer_remove()"
```

Fix T50530: Crash on Info Editor "console"

Introduced on rB2de882e8 - the original size of the array was neglected

Alembic: fix compile error on Linux.

Fix T50287: Blender crashes when open a blend that contains an alembic
file.

Missed in rB62a2ed97b.

[Cycles/MSVC/Testing] Fix broken test code.

Currently the tests don't run on windows for the following reasons

1) render_graph_finalize has an linking issue due missing a bunch of libraries (not sure why this is not an issue for linux)
2) This one is more interesting, in test/python/cmakelists.txt ${TEST_BLENDER_EXE_BARE} and ${TEST_BLENDER_EXE} are flat out wrong, but for some reason this doesn't matter for most tests, cause ctest will actually go out and look for the executable and fix the path for you *BUT* only for the command, if you use them in any of the parameters it'll happily pass on the wrong path.
3) on linux you can just run a .py file, windows is not as awesome and needs to be told to run it with pyton.
4) had to use the NAME/COMMAND long form of add_test otherwise $<TARGET_FILE:blender> doesn't get expanded, why? beats me.
5) missing idiff.exe for msvc2015/x64 in the libs folder.

This patch addresses 1-4 , but given I have no working Linux build environment, I'm unsure if it'll break anything there

5 has been fixed in rBL61751

Fix T50115: stereoscopic video file memory leak

Fix T50032: Wrong render result when same image is used with and without alpha

Fix T50512: Linked Backround scene with animation not updating with new depsgraph

Was missing relations for the set scenes.

Perhaps not ideal solution, but should be good enough for now.

Depsgraph: Do ID tag outside of build_scene

Otherwise it was possible to get ID tags cleared in the middle
of DEG construction when there are set scenes used.

Fix T50517: Rendering expecting time is negative

Convert MBC_ API to Mesh (instead of derived mesh) and move it to mesh_render

This includes a few fixes in the MBC_ api.

The idea here is for this to be the only interface the render engines
will deal with for the meshes.

If we need to expose special options for sculpting engine we refactor
this accordingly. But for now we are shaping this in a per-case base.

Note:
* We still need to hook up to the depsgraph to force clear/update of
batch_cache when mesh changes

(I'm waiting for Sergey Sharybin's depsgraph update for this though)

* Also ideally we could/should use BMesh directly instead of
DerivedMesh, but this will do for now.

Note 2:
In the end I renamed the `BKE_mesh_render` functions to `static
mesh_render`. We can re-expose them as BKE_* later once we need it.
