Fix own stupid mistake in recent mesh 'split_faces' rework.

Was assigning new edge index to ml_prev->e, and then assigning ml_pre->e
to orig_index...

Get UI ready for using drag & drop to nest a collection into another one

Nothing happen yet when it's supposed to insert the collection into
another one, that part will be handled by @dfelinto.

See gif for demo of how it works UI wise: {F500337}

Also fixed off-by-one error in utility function.

Remove all instance of OBACT from particle_edit.c and related changes

Remove all instances of OBACT from drawobject.c and related changes

Remove OBACT from rigidbody_constraint.c and remove uneeded sanity check

Remove tons of OBACT

There are now only referenced in:
* drawobject.c
* particle_edit.c
* space_image.c (a single case to be handled on workspace branch)
* rigidbody_constraint.c (to be handled in the following commit)

Edit Mesh overlay: pack normals with face centers.

Needed for face normals.

Mesh batch cache: fix memory leak

Fix duplicated 'Accurate' property for manipulator keymap item

Is already added through Transform_Properties

Fix weird "use_planar_constraint" button in redo panel

Issue was that the VIEW_OT_manipulator operator calls the transform
operators and passes them it's own operator properties. That means the
transform operator got properties passed that it doesn't have.

Revert "Depsgraph: Add placeholder function to handle objects update"

This reverts commit 9023abbf27c4efcdba3d9bd7c884680e56e4d9cb.

Fix mesh edit wasn't updating for new objects

The problem was that we were updating the mesh cache on
BKE_object_eval_shading, not on mesh change.

Threads: Use atomics instead of spin when entering threaded malloc

Fix another part of T50565: Planar constraints were always initialized to accurate transform

Now it is defined by keymap.

Fix second part T50565: Using planar transform once makes it enabled by default

Was caused by property being saved by the operator manager.

Fixup for layer rename unittest (rB3baa186724)

Layers unittest: isolate the depsgraph crash in individual tests

(and re-order the tests alphabetically)

Gawain: allow use of final 2 bits of 10_10_10_2 format

Requested by @fclem

Edit Mode overlay: Moved Shaders to draw modules and resolved some draw issue.

We don't want to clutter gpu_shader.c with engine specific code
Added face's center dot
Simplified loose vert shader

Edit Mode overlay: Added theme color via UBO.
