Fix selection randomly failing with border render.

We no longer user scissor for 3D viewport drawing, and some selection
code assumed it still. This also cleans up unnecessary scissor test
switching, we only have it temporarily enabled now.

make.bat: fix support for building with just the build tools installed.

Fix Cycles UI script error with denoising.

Fix Cycles viewport render stuck with curve objects.

We should solve this better by making the depsgraph convert all curves to
meshes, for now ensure we don't to depsgraph tags during export.

Depsgraph API: renaming, more granular update information.

* depsgraph.ids: all evaluated datablocks in the depsgraph
* depsgraph.objects: all evaluated objects in the depsgraph
* depsgraph.object_instances: all object instances to display or render
* depsgraph.updates: list of updates to datablocks

Render API: rename some API functions back to earlier names.

Their purpose is the same, no reason to break API compatibility here.

UI: use split property layout for some panels

Object, render, scene properties now use split-property layout,
also cycles interface.

Patch by @billreynish w/ minor edits.

Cleanup: quiet warning

UI: fix property split w/ color buttons & empty text

Tweak for previous commit: Just group all bone properties under the bone name

After more testing, I realised that bendy bone properties should also be grouped,
but probably all other per-bone settings too. Now, just group all of them, since
it's easier for everyone this way.

Modifiers: Bring back custom data referencing logic

Brings dependency graph evaluation time to similar time than 2.79
for file reported in T55228.

Modifiers: Make input of modifier stack referencing copied CD layers

The idea is to allow modifier stack to reference custom data layers
from copied version of mesh datablock.

Modifiers: Restore duplication of referenced layers

Was no reason to remove those calls, it was always a plan to bring
referenced layers back eventually.

Insert Keyframe: Change default behaviour for how F-Curves get grouped

For many years, animators have been complaining about how keyframing a (transform)
property directly would leave them ungrouped, while keyframing them using a Keying Set
would put them into a group based on the name of the keyingset.

This commit attempts to improve (unify + make consistent) the default behaviour:
* All object transforms now get added to an "Object Transforms" group,
regardless of whether they were added individually via buttons or keyingset
* All bone transforms now get added to a group corresponding to the name of the bone
instead of only the ones added via keyingset

Cleanup: Reuse existing scene pointer

Merge branch 'master' into blender2.8

Conflicts:
source/blender/editors/space_outliner/outliner_intern.h

Fix missing movieclip ID type in allowed ones for Outliner...

Object Modes: don't de-select others when activating

Fix render info not working with overlap regions

Object Modes: stay in object mode when setting active

When activating an object from the 3D view or outliner,
keep the newly selected object in object mode.
