3D View: option only to show axis aligned image empties

Useful for using reference images that only make sense to see
in aligned axis-views.

This restores functionality possible with 2.7x background images.
See: T52668.

rename attribute reference classes

AttributeArrays -> AttributesRef
NewParticles -> AttributesRefGroup

Fix T69326: Parent type ARMATURE doesn't work

Depsgraph: Cleanup, more clear variable name

Depsgraph: Cleanup comment

Merge branch 'master' into functions

New approach to accumulating part-part intersections.

Implemented simple face-face intersections now.

Drivers: add separators to the Transform Channel type enum menu.

It's hard to find things quickly in the wall of '...ation' without breaks.

UI: Fix Bug With Join Area Tolerance

Join area tolerance not properly checking all vertices on shared edge.

Differential Revision: https://developer.blender.org/D5662

Mantaflow: Fix for versioning issue

Fixes crash with old fluid (Elbeem) modifier

Mantaflow: Fix for noise density issue

Emission values for noise need to be upscaled with upres factor

reorganize where interfaces are declared

Return proper RNA path in py console for 'private ID' data.

We can now generate a proper path here, make use of it.

Note: not sure how property pyrna path is supposed to be accessed? code is
similar to the struct pyrna path anyway...

Fix/enhance new RNA path from real ID helpers.

Main issue was that `rna_prepend_real_ID_path()` would return
nothing in case given path was NULL, when it should actually return the
`prefix` computed by `RNA_find_real_ID_and_path()` in that case...

Also make return `real_id` pointer optionnal, no reasons to make it
mandatory here. And some general naming fixes.

DatablockManagement: Cleanup: get rid of `BKE_collection_copy_master()`.

Now that we 'properly' support private ID data in lib management, there
is no reason anymore to have that custom func, badly named and
by-passing the whole generic ID management code.

DatablockManagement: Fix/sanitize handling of flags for private ID data in copy functions.

Not sure exactly why that was working with nodetrees in depsgraph (could be some special
code in the despgraph), but we always want to allocate memory for the nodetrees here!

Cleanup: get rid of BKE_collection_master() useless accessor.

In its current version that was a totally useless extra layer of crap
that we can totally avoid. Plus name was bad too.

DatablockManagement: Cleanup logic of private IDs handling in `BKE_libblock_copy_ex()`.

Now that we have the private ID data flag, we can be more simple *and*
generic here.

Make Scene Master collection 'Private' ID data, like root nodetrees.

Same issue here as with root nodetrees, those are private ID data owned
by another ID, and not in Main DB. This requires special handling.

there are still quiet a few things to do here, like getting rid of
special code for master collection (regular ID copying should handle
that just as it already does for root nodetrees), cleanup in ID copying
code, etc.
