Build: fix make deps TBB on Linux, older versions don't support GCC 7.

Build: fix make deps OpenSubdiv build on Linux.

Outliner/Collection: Interface for Master Collection Tree

This is part of T53495.

This adds an Edit menu and remove the buttons.

Outliner/Collection: Operator to delete selected collections

This is part of T53495.

This operator is actually using existing code. The only new thing about it is
that it has a shortcut.

It will be exposed in the UI soon together with the nested collection operator.

Outliner/Collection: Operator to create (nested) collections

This is part of T53495.

This operator is intended for the outliner when viewing Collections (at the moment, Master Collection Tree).
It has a shortcut "C", and will be added to a menu shortly.

Fix T53513: Particle size showing in multiple places

Technically this was introduced in 01b547f9931970050e when
exposing size and randomness for particles.

This "fixes" makes sure particle size and size randomness is always in the
Render panel when it affects the particle system (i.e., always unless using
advanced hair or hair that is not rendering groups/objects).

Fix T53647: Outliner crashes when active object is deleted

Based on patch by Philipp Oeser (lichtwerk).

Fix T53639: text sequence strips no stamped into render.

Differential Revision: https://developer.blender.org/D2977

Fix mistake in previous fix for T53600, shows we really need a smarter solution.

Fix T53630: Effect strips not displaying Input data.
Fix T52977: Parent bone name disappeared in the UI in pose mode.

Regression caused by own rBc57636f060018. So instead of changing widget
type, just flag it as disabled.

Note that core of the issue is elsewhere though - there is absolutely no
reasons to have a search widget for pointers we cannot change nor
search! But fixing this is not really top priority, one of the many
glitches of our UI code, so think we can live with current code.

To be backported to 2.79a.

RNA cleanup: Argument names + tooltip for scene_collection.collections.remove()

Context: Fix scene_collection

We now allow for scene collection that is not currently linked to view layer.

RNA: scene_collection.collections.new() name optional

We already have a fallback naming system when no naming is given, we should use that.

Cleanup after collection rename commit

Related to c9cb5dc3dab0.

Collections: Allow collections from different "parents" to have the same name

This allows users to have "Support", "Rig", "Characters" collections nested to
different collections without having to resort to "House.Rig", "House.Characters"
or "Rig.001", "Characters.003" :/

This is part of T53495.

Fix missing redraws when changing active view-layer or its name

Also removed unnecessary `struct` keywords.

Fix T53638: View layer renaming crashes 2/2

This fixes renaming the view layer via Python.

This bug was introduced originally in 3a95bdfc65d. Although I suspect it was
around for longer, since this commit didn't touch this part of the code.

But basically we need the id of the RNA property to be the one that owns
the data (view layer).

Fix T53638: View layer renaming crashes 1/2

This fixes renaming via the interface.

This bug was introduced originally in 9515737b554. We need the id of the RNA
property to be the one that owns the data (view layer).

So it can't be the window's id, but the scene one instead.

Depsgraph: Fix copy-on-write assert when freeing Freestyle config

We were bumping user count when duplicating viewlayer and its freestyleconfig
depending on the flag, however when freeing we were always decreasing user
count.

This fixes this and get rid of the assert when running:
`--factory-startup --enable-copy-on-write`

And closing Blender.

Fix T53600: Cycles shader mixing issue with principled BSDF and zero weights.

SVM nodes need to read all data to get the right offset for the following node.
This is quite weak, a more generic solution would be good in the future.
