Fix T54366: Custom manipulator acts on linked data

Fix crash when changing workspaces

Steps to reproduce were:
* Append a workspace (via '+' icon) - make sure its from the default workspaces.blend
* Activate it
* Should crash

Was accessing data from view-layer which wasn't updated yet (and thus could be
NULL). Crash occured after rB8153f89518b4a.

@campbellbarton, you may want to check if all object-mode stuff still works as
expected, not sure what's the state of it.

Link and expand overrides for collections

This code was neglected. Yet it is needed for when we support datablock
overrides so that the ID pointers are properly linked and expanded.

Cleanup: remove useless static override reference pointer from ID struct.

Add basic read-only RNA access to static override data.

Will make investigating issues much, much easier!

Fix broken tatic verride detection in RNA collections.

We have to check all items of a collection when we want to create
overrides as needed...

Fix build error on Windows 32 bit.

Merge branch 'master' into blender2.8

Remove debug only code from previous commit

Memory allocator: Clarify consistency check function

Also make it to return truth when everything is good and
false otherwise.

Depsgraph: Fix memory leak when datablock is not reused

It is possible that datablock will not be re-used for the new
dependency graph building. Freeing function was freeing all
the nested pointers of databnlock, but not datablock memory
itself.

Depsgraph: Prevent non-expandable datablocks from being freed

This avoids original image datablock destruction when using
copy on write.

MSVC: Fix lite build.

MSVC still defines __cplusplus as 199711L until it's in full conformance with the newer c++ standards, however the things we need from the standard are fully supported, hence a check for the msvc version was needed.

DRW: Fix bound_ubo_slots allocation size.

DRW: Fix ubo binding code.

Fixed: cache clearing when using multiple Alembic files.

Fix BLI_assert for MSVC

Also use `_BLI_ASSERT` prefix for internal defines.

Fix missing ID pointer handling in materials in ID remapping code.

Fix missing array duplication when copying material

Texture paint slots were copied as a pointer, causing double-free.
