Snap System: missing change

Merge branch 'master' of git@git.blender.org:blender.git into blender2.8

Snap System: fix rename `ob` to `obj`

This would bring problems with dupli objects

Depsgraph: Initial support of armatures for copy-on-write

This commit makes simple cases to work, for example:

- IK solver to an external object
- Object with Armature modifier, "parented" to the deforming armature
(via animation).

More complicated setups (like agent rig) are crashing still.

Another fix for snapping after merge in 2.8

Fix snap in 2.8 after poor merge from master

If you merge from master to blender2.8 after a commit, remember to test in 2.8, otherwise what is the point?
Specially if it's a non-essential commit such as c9817c67fc141ca85a6e1f9e42d9fa.

Bug introduced on: f4155d3778ba883566eeb87d16218c4c275ffc (the merge
that included the above commit).

Revert "Fix T51794: Crash on hair file when opening with no UI"

This reverts commit 0095f4f83465bc9fdc13b79d2126f5623e291d7c.

Workspace: Fix crash on preview, and sanitize placeholder functions

This commit effectively makes workspace switching useless as far as the
active scene layer goes.

The functions from the scene layer API to get the correct scene layer
from "context" were a placeholder to be addressed by the workspace
commit.

When workspace was merged, however G.main was used as a replacement to pass the
correct argument for the functions. As it turned out (surprise!) this
leads to crash on render preview.

We need to get rid of:
* BKE_scene_layer_context_active_ex_PLACEHOLDER
* BKE_scene_layer_context_active_PLACEHOLDER

And either use SceneLayer explicitly or replace it by:
* BKE_scene_layer_from_workspace_get

now alpha effect can be seen in 3d view in vpaint

Fix unit test error on Windows

Cleanup: use 'r_' prefix for return args

Cleanup: long lines

DwM: Show face-mask overlay even with full-shading

Without this face selection would be used but invisible,
display this over fully shaded surface.

Fix T51945: LMB select swaps manipulator buttons

Fix T51979: Eevee: Bloom artifacts w/ zero area faces

Revert "Eevee: Fix the NaN pixel issue."

This reverts commit d02711ed883ee0d1844d49d39a8814aca5b029c3.

Snap System: Replace creation and destruction of the object list by a Macro

The macro got a little strange, but it's better than using the MEM_mallocN inside a loop, or repeat the lines
