Fix T50369: Objects can't be deleted from scene when using "link group objects to scene"

Main issue here was that in old usercount system 'user_real' did simply
not allow that kind of thing to work. With new pait of 'USER_EXTRA'
tags, it becomes possible to handle the case correctly, by merely refining
checks about indirectly use objects whene removing them from a scene.

Incidently, found another related bug, 'link group objects to scene' was not
incrementing objects' usercount - bad, very very bad!

Fix T50350: Quick Explode time frame problem

The settings.frame_start rna was clamping frame start to frame end when frame start was bigger than frame end.
The fix is simply to set frame end first

Move workspace DNA back into DNA module

Added some special include guards to protect from access from outside of BKE_workspace and makesdna.

Properly append screens with workspaces

Meaning screen data is now fully editable when appending a screen(-layout) indirectly by appending a workspace. Screens aren't visible while browsing inside .blend files, don't think we need/want that.

Merge branch 'blender2.8' into workspaces

Make workspaces appendable, but non-linkable

This basically adds support for data-blocks that are either linkable, appendable or both and uses it for making workspaces appendable only. Note that non-appendable but linkable data-blocks aren't used currently and poorly tested, added note about this in code.

Silly const mistake (missed in refactor...)

Merge remote-tracking branch 'origin/master' into gsoc2016-improved_extrusion

Implement target poly influence interpolation

Add 3d to 2d plane mapping functions to math lib

Curves: Chamfer and fillet operators

Fixed some inconsistency on user interaction:

- Chamfer and fillet only enter modal when the selected handle is vector type
- Commented all the tools implemented from the Specials menu. They were not being called on modal.

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

Revert "Remove double menu entries"

This reverts commit e2d7efc9503720770b9652284e25006eecbec8d4.

Fix implicit size_t to int conversion.

Seems like it was erroring on some buildbots...
