Libmv: Update tests to make tests pass after recent Ceres update

Just a precision issue, difference is around 1e-7. Should be fine to
simply update expected value.

Solve threading conflict when calculating smooth normals

It was possible to have synchronization issues whe naccumulating smooth
normal to a vertex, causing shading artifacts during playback.

Bug found by Dalai, thanks!

COLLADA: Removed obsolete Export select option 'Both' which created invalid data (duplicate transformation information for nodes)

Depsgraph: Fix some errors printed to the console

They were not real issues, it's just some areas of code tried to create
relations between non-existing nodes without checking whether such
relations are really needed.

Now it should be easier to see real bugs printed.

Hopefully should be no regressions here.

Fix UI for smoke cache

(this was probably broken since we got rid of point cache in 2.8)

Merge remote-tracking branch 'origin/master' into blender2.8

Cycles standalone, compile fix UINT_MAX is not defined in device_cuda.cpp

CMake: Make ld.gold linker optional

Some platforms are having hard time using this linker so added an option
to not use it. The options is an advanced one and enabled by default so
should not cause any changes for current users.

CMake: Fix use of some option which was never defined

This way it seems more logical to me.

[msvc/make.bat] Detect spaces in the build path and error out.

Change frame for animations should not bein the UNDO stack

Request from Hjalti Hjalmarsson for the animation work.

Basically a common part of the workflow of animation is to change the pose, scrub back and forth a few times and roll back the changes when unsatisfied.
However if you go back and forth too many times the UNDO stack would be full, and it would not be possible to bring back the previous pose.

I'm leaving clip_editor change frames as it is for now. But we can
probably change the behaviour there as well.

Add 'copy array' for rna buttons

ctrl-alt-c/v allows to copy/paste whole RNA array, e.g. location, rotation, etc., from UI buttons.

Request from Andy at the studio.

Fix T49856: Blender 2.78 crashes after loading data from a blendfile

Issue here was that py API code was keeping references (pointers) to the
liniked data-blocks, which can actually be duplicated and then deleted
during the 'make local' process...

Would have like to find a better way than passing optional GHash to get
the oldid->newid mapping, but could not think of a better idea.

Ceres: Update to the latest actual version

Brings all the fixes and improvements done in upstream within the last 13 months.

OpenGL: draw NLA strip curves with new imm mode

Part of T49043.

Added 'delete unlocked vertex groups' option.

BMesh: radial loop (internal API symmetry)

Radial append/remove had swapped args and *slightly* different behavior.
- bmesh_radial_append(edge, loop)
- bmesh_radial_loop_remove(loop, edge)

Match logic for append/remove,
Logic for the one case where the edge needs to be left untouched
has been moved to: `bmesh_radial_loop_unlink`.

BMesh: simplify vert & edge removal

BMesh: remove redundant walker member & assignment

Cycles: Deduplicate AO calculation

No functional changes.
