Fix out of bounds memory access in interp_weights_face_v3

interp_weights_face_v3 required a length four array for weights even when
calculating weights for a tri, otherwise, it would access unkown memory.
This fix allows a weight array of size three to be passed when only
calculating tri weights.

Add basic code to prevent editing non-overridable properties.

More work and refactor in RNA override part mostly.

This commit mainly extend/refactor RNA prop copy and equals functions
into more advanced override utils (since equals is a subset of
aurooverride operations generation, and copy is a subset of override
operations application).

And some other work needed on the road...

Massive fixup on BLI_iterator and the iterators using it

From review: handle post processing of objects after they are removed

unittest: object delete

From review: proper handle of library_query

Beginning Clay Viewport Engine :
- Added temporary draw_mesh function to render edit mesh
- DRW_draw_batch_list allows to render a list of objects with optimal state change
- All viewport rendering is done offscreen for the moment

Signed-off-by: Clément Foucault <foucault.clem@gmail.com>

fix when using inner vertexgroup, weights of other vgroups on the same mesh were deleted by accident then

Add first basic working auto-override.

Still called from pre-depsgraph eval step, does an RNA comparison and
generate overriding rules for changed props...

Note: we most certainly do not want to run this on all depsgraph eval.
Own current idea would be to just tag IDs e.g. in depsgraph callback,
and run actual auto-generation e.g. in a low-priority job, maybe? not
sure... :|

Also, fix stupid mistake in RNA applying of override (used when reading
file to apply static override), and add object's loc/rot/scale as
overridable properties.

ID override static: Various minor fixes and tweaks.

unittest: fixup

Make workspaces append-/linkable

TODO:
* Make indirectly linked screens local.
* Make workspaces only appendable, it doesn't make sense to link them.

Rename "Default" workspace to "General"

Default screen-layout is still called "Default", not sure if we should change that. Ideally the layouts shouldn't be identified by names anyway.

Remove workspaces/screen-layouts from default startup.blend except of "Default" one

This means in the default startup.blend, there's only going to be one workspace and one screen-layout, both called "Default" (will be renamed to "General" though). Idea is that users will have the option add a pre-configured workspace from a menu. This avoids cluttering screen space with workspaces the user won't use even.

For compatibility, screen-layouts from old files are still converted to workspaces, this only affects the default startup.blend.

Use new after lib-linking versioning

Merge branch 'blender2.8' into workspaces

Deprecate Screen.scene completely

Removing a custom transform orientation is a bit broken right now because we don't know which scene is visible in hidden 3D Views. Think I know how to fix this, but want to go on with other stuff first.
