Fix warning

Cycles: Free evaluated meshed when we are done with object

Cycles: Fix memory leak with session

We didn't check for sync object being already allocated.
In fact, we simply need to use proper function to free
session.

Physics: update softbody and dynamic paint to get colliders from depsgraph.

Because looping over the scene is unsafe and slow.

Cleanup: refactor depsgraph physics API functions.

UI: Single-column layout for Force Fields and Particles

Force Fields and Falloff are now simpler and more compact
by removing unnecesary labels (there was a text label just for one option)

Particle Force Fields Falloff is now a sub-panel of each effector type,
rather than just as a section with label.

UI: Single-column layout for View Layer, passes and World

UI: Single-column layout for Texture Color

UI: Single-column layout for Shape Keys and Geometry Data

do not set edges of selected faces to sharp in external mode

because in most cases only existing objects are packed into the FM mesh, and no fracturing happens,
where you want to set fracture edges to sharp.

Fix T55360: marker-based Camera switch focal length bug.

Scene was missing DEG tag update when its camera was changed based on
active 'camera marker'.

Drawing code moved in, but most parts need redo.

Fix T55493: Sculpting on smooth shaded bug.

Undo was not tagging PBVH to update normals too...

Fix use of non-evaluated collision and effector objects.

Only enabled objects in the view layer should be used, while temporarily
hidden objects should still have an effect.

Cleanup: rename object base flags to be more clear.

Depsgraph: cache collision relations, for performance and stability.

Same reasoning as effector relations in earlier commit.

Cleanup: Move colorband handling from DM to mesh_runtime universe.

UI: In user preferences group Developers Extra and Python Tooltips

Move Navigation Manipulator toggle next to Mini Axis as they are related
(and in the future merged into one pulldown) and rename Manipulator
to "Transform Manipulator" to make it clear they're different kinds
of manipulators. Also move to the first column next to other viewport settings.

Merge branch 'master' into blender2.8
