Merge branch 'master' into blender2.8

Depsgraph: Introduce flag top indicate scene is evaluating for a new frame

Depsgraph: Preserve CoW ID recalc flags

Previously they would have been replaced with flag from original
datablock, which is not what we want.

Depsgraph: Ensure we only expand scene datablock on evaluation

Previously it could have happened on every request to evaluated scene
or view layer.

This commit also removes expansion of view layer and scene from iterator.
Iterator is not to be used before depsgraph is evaluated.

Depsgraph: Avoid hash lookup for every evaluated scene query

Cache pointer to evaluated scene datablock on relations build time,
that pointer never changes after that.

Depsgraph: Fix missing relations in array modifier

Found by Dr. Sybren while working on modifiers port.

Workbench: Added studio lighting to view layer

Revert "UI: fix inconsistency in button rounding when zooming in."

This isn't working well when zoomed out in the properties editor,
we should be taking into account properties editor zoom level.

This reverts commit 1ba91ae2c02863b3fd97810e7bcee902dac58992.

Introduced CDDM_from_mesh_ex() to create a non-referencing CDDM

This allows the mesh to be freed and the CDDM kept.

Vertex merging in mirror modifier is working

Also fixed some memory issues.

Fix multi-edit mode on file load

Setting up the initial object mode would change objects which were
already moved into their mode along with the active object.

CDDM: correct (disabled) logic in merge verts

Almost finished mirror modifier (still needs vertex merging)

added isIntact() query to regular rigidbody constraints, too

Search local before system path

This works in both cases,
where system path would return a path even when it's missing.

Fix T54806: Editors drawing glitch when using lasso selection
