Depsgraph: Object data separation, lamp

Depsgraph: Object data separation, light probes

This is a beginning of series of commits which will clearly separate
building IDs which are used as object data from object building.

The goal is to be able to always build whatever ID. Required to make
driver targets to work reliably with copy-on-write concept.

Depsgraph: Remove confusing metaball logic

DATA datablock must evaluation must never depend on object it is
used for. If there is something what depends on an object, it must
be done on object level.

At least the actual callback was empty.

Wireframe: Fix do_version.

Ensure BKE_mesh_new_nomain_from_template() always has valid mxxx pointers

When the source mesh doesn't have the primary layers (CD_VERT for vdata,
etc.) the returned mesh also didn't have those layers, even when non-zero
elements were requested (for example requesting 4 vertices would still
result in mvert = NULL).

Consolidated custom data layer initialisation

Code shared between BKE_mesh_new_nomain() and
BKE_mesh_new_nomain_from_template() is now in separate functions, instead
of copy-pasted.

Set mesh->totface in nomain-mesh creation

The totxxx fields should match the number of elements in their respective
custom data layers.

Fix T55344: linked collection instance has user count 0.

UI: tweak for Cycles panels.

Cleanup: fix compiler warning.

Fix importing temporary screens

Apparently Blender 2.79 could save temporary screens; those should not be
converted to workspaces.

Renamed BKE_nomain_mesh_xxx ? BKE_mesh_nomain_xxx

This maintains the `BKE_mesh_` prefix for the mesh-related BKE functions.

DerivedMesh deprecation: Removed some functions in displist.c

Those functions were using DerivedMesh but are not called from anywhere.
As a result, they cannot be tested after porting DerivedMesh to Mesh.

DerivedMesh deprecation: marked no-longer-in-use function

Functions that are no longer in use can be marked as such, so that later
we can easily remove them.

Modifiers: ported curve_calc_modifiers_post() internals from DerivedMesh ? Mesh

The function still returns a DerivedMesh, but internally it uses Mesh
now.

Error in recent popover keep_open option

Merge branch 'master' into blender2.8

Fix error using freed bmain

Regression in 481cdb08ed6f3

Cleanup: rename WITH -> USE for internal defines

Cleanup: USE_UI_* prefix for UI defines

Otherwise there is no quick way to see where this comes from.
