Static override: initial work for generating 'insertion' in collections.

Does not yet support applying those operations, only detecting
insertions and generating matching rules was already rather complicated.

Also got rid of ;ost rna_path string allocation in collection diffing
code, could help a bit with speed too.

Merge remote-tracking branch 'origin/blender2.8' into temp-modifier-rm-cddm

added support for obj mesh caching

more mesh improvements

added more smoothening settings and a preview/final mesh switch

UI: move object selector into 3D view

This matches the new convention for left-handed mode selectors,
however we're still undecided on exactly how this should work.

For now test this out as a convention for all space types.

Eevee: Don't enable temporal AA when using 1 sample only.

This was producing infinite rendering but wasn't noticeable.

Eevee: Shadows: Only tag as shadow caster if a shadow is cast.

This leads to great improvement if the scene have moving objects without
shadows (shadows disabled in the material panel).

improved cache formats

now supporting openvdb and others - manta handles file IO

Workbench: Shadows

Fix negation of light direction
added SHOW_SHADOW_VOLUME option

GP Properties: Separate onion skinning for datablock + per-layer override into separate panels

The panel layouts are still a mess, but at least there's less code duplication
and weirdness now, with everything taking advantage of more conventions here.

Cleanup: Material Buttons for GP

* Don't collapse panels by default
* Cleanup old code/names/etc.

UI: move space-mode selectors before menu items

This adds a convention to have a spaces primary mode selector
positioned to at the left of the header.

Modifiers: Fix crash when entering edit mode on unported modifiers

Fix number sliders for the topbar

Extract common modifier parameters into ModifierEvalContext struct

The contents of the ModifierEvalContext struct are constant while iterating
over the modifier stack. The struct thus should be only created once, outside
any loop over the modifiers.

Formatting

Modifiers: Array DerivedMesh ? Mesh

Introduced CDDM_from_mesh_ex() to create a non-referencing CDDM

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

Modifiers: Mirror DerivedMesh ? Mesh

Modifiers: Armature DerivedMesh ? Mesh

The mesh parameter of armature_deform_verts() is now const, to indicate
that it's safe to pass ob->data to it directly.
