Add ui_scale factor to color picker

Further fixes to new RNA props diff code.

Unfortunately, we cannot perform set/unset checks on 'resolved'
properties (i.e. from actual IDProperties pointers, and not virtual RNA
placeholders)... IDProps in RNA are rather challenging topic. :|

This should fully fix T53715: 2.8: Removing keymap items no longer works

Fix T53311: transform edge/normal orientation

When the edge is aligned with it's own normals,
transform orientation wasn't aligned with the edge.

Fix T53755: Cycles OpenCL lamp shaders have incorrect normal.

UI: option not to show screen splitting widgets

Request for simplified Blender template,
this may be extended to limit access to other UI changes
that could be pressed by accident.

Merge branch 'blender2.8' into asset-engine

Merge branch 'master' into blender2.8

UI: don't draw outline when it's not calculated

Outline drawing was running even when there were no verts to draw.
Causes an assert in 2.8.

Cycles: support animated object scale in motion blur.

This was disabled previously due to CUDA compiler bugs, see T32900.

Differential Revision: https://developer.blender.org/D2937

Fix generating dummy pixel data

Range was for an unsigned int instead of an int,
caused overflow error

Fix T53752: Draw curve fails w/ stylus

Fix T53455: Object disappear w/ TrackTo constraint

Regression caused by own commit 16fbb47c886,
this is really an edge case though since calling normalize twice fixes.

Cleanup: BKE naming conventions for datablock add/localize

Conventions were already followed nearly everywhere.

Fix Windows compiler warning using WITH_CYCLES_NATIVE_ONLY.

Fix issue with moving CUDA memory to host and multiple devices.

This is not expected to fix all issues. Also adds some more details
to error reporting to investigate failures.

Fix T53692: OpenCL multi GPU rendering not using all GPUs.

Ensure each OpenCL device has a unique ID even if the hardware ID is not
unique for some reason.

Cleanup: Naming, avoid passing bContext to low-level function, etc

Fix crash when deleting collections

With factory settings, steps to reproduce were:
* Select "Collection 1" (in "RenderLayer")
* Delete
It might crash at this point, although maybe this crash is ASAN only.

However, this was also doing some weird things that I've corrected now. It
called outliner_build_tree in an operator callback. This should only be
called in the main redraw function or so, not in regular handlers.
Instead, we manually cleanup the tree to keep it valid.
