This is a workaround required to get BAT reliably working again after
recent rB133dde41bb5b, which fixed many indirectly linked IDs being
tagged as directly linked, and therefore having their reference written
in .blend file.
It seems that BAT is still missing proper handling of some ID pointers.
Required for the end of the Heist production here at Blender Studio.
rB9fa4ceb340951 caused a forward compatibility issue.
Going forward, when changing socket names, only the name should be
changed and not the identifier if possible.
The existing `DisjointSet` data structure only supports single
threaded access, which limits performance severely in some cases.
This patch implements `AtomicDisjointSet` based on
"Wait-free Parallel Algorithms for the Union-Find Problem"
by Richard J. Anderson and Heather Woll.
The Mesh Island node also got updated to make use of the new data
structure. In my tests it got 2-5 times faster. More details are in 16653.

90ea1b7643 broke the sorting that happens as nodes are selected.
The compare function for stable sort had different requirements than
the previous implementation.
This patch adds an integer identifier to nodes that doesn't change when
the node name changes. This identifier can be used by different systems
to reference a node. This may be important to store caches and simulation
states per node, because otherwise those would always be invalidated
when a node name changes.
Additionally, this kind of identifier could make some things more efficient,
because with it an integer is enough to identify a node and one does not
have to store the node name.
I observed a 10% improvement in evaluation time in a file with an extreme
number of simple math nodes, due to reduced logging overhead-- from
0.226s to 0.205s.

Use recently introduced BKE_fcurve_merge_duplicate_keys (that was moved
from the transform system to BKE) to merge keyframes on the same frame
after snapping (same as what would happen with the transform system).
This makes behavior consistent and prevents a state after snapping that
cannot be reproduced in any other way.
NOTE: same probably has to be done for greasepencil, but that is for
another commit.
This exposes the fcurve cleanup from transform system to other callers
in anticipation to use it in the snapping operators.
It has been renamed from `posttrans_fcurve_clean` to
`BKE_fcurve_merge_duplicate_keys` to better describe what it does.
No functional change expected.

Introduced in fc7beac8d6, but I think this never worked because the
`asset_library_ref` of the temporary file-list used for reading in a
background thread is nulled. Now there's a different pointer that we can
use that works properly.
Two things here:
- fix ghash lookup from rB4d497721ecd1
-- this was looking in the wrong map (causing an assert on file load)
- set MovieTrackingObject active_plane_track to NULL upon deletion (same
as for regular tracks)
-- rBfe38715600c introduced a crash because `draw_tracking_tracks` would
still get an active plane track (logic for getting these changed)

a5e7657cee missed this call where clamped slicing is necessary.
The subdivision of a segment purposefully modifies the handle types of
the other side of the following control point, but that didn't work for
the final cyclic segment.
The code I wrote to group triangles or multires quads that
belonging to single faces into single PBVH nodes had edge
cases that failed. The code is now much simpler and simply
assigns groups of primitives to nodes.
When entering paint modes the paint pivot was cleared,
which broken rotate around pivot. Fixed for all paint modes.
PBVH modes set the pivot to the PBVH bounding box
while texture paint uses the evaluated mesh bounding box.
If no brush exists the stroke operator
falls through to the grab transform
op in the global view3d keymap.
This now works. It would be nice if
we could get rid of that keymap entry
though and add it manually to the edit/paint
modes that need it.
Materials now have an enum to set the emission sampling method, to be
either None, Auto, Front, Back or Front & Back. This replace the
previous "Multiple Importance Sample" option.
Auto is the new default, and uses a heuristic to estimate the emitted
light intensity to determine of the mesh should be considered as a light
for sampling. Shaders sometimes have a bit of emission but treating them
as a light source is not worth the memory/performance overhead.
The Front/Back settings are not important yet, but will help when a
light tree is added. In that case setting emission to Front only on
closed meshes can help ignore emission from inside the mesh interior that
does not contribute anything.

This cache was never written to, only "copied" between sockets in one
case, it dates back at least a decade. It doesn't make sense to store
caches on node trees directly anyway, since they can be used in
multiple places.
No user visible changes expected.
Add a function to query the full path for a file, so that asset files
can get the path via the asset representation and its new asset
identifier. This is designed to be a reliable way to locate an asset,
and using it is yet another step to rely less on the problematic file
browser code.
Also, previous code would build the full path manually in a few places,
which is good to deduplicate anyway.
With the asset identifier introduced in the previous commit, we can now
locate an asset just from its `AssetRepresentation`, without requiring
information from the asset library and the file browser storage. With
this we can remove some hacks and function parameters. A RNA/BPY
function is also affected, but I didn't remove the paramter to keep
compatibility. It's simply ignored and not required anymore, noted this
in the parameter description (noted for T102877).
No user visible changes expected.
`AssetIdentifier` holds information to uniquely identify and locate an
asset. More information:
https://wiki.blender.org/wiki/Source/Architecture/Asset_System/Back_End#Asset_Identifier
For the start this is tied quite a bit to file paths, so that external
assets are assumed to be in the file system.
This is needed to support an "All" asset library (see T102879), which
would contain assets from different locations. Currently the location of
an asset is queried via the file browser backend, which however requires
a common root location. It also moves us further away from the file
browser towards the asset system (see T87235) and allows us to remove
some hacks (see following commit).
No user visible changes expected.
If an asset library is located on disk, store the path to it in the
asset library data. This is called the "root path" now.
With this we can construct an asset identifier, which is introduced in
the following commit.
When reading directories recursively, the code would first only set the
file name as the relative path and then later iterate over the read files
and prepend the recursed into path, to get the complete path relative to
the recursed into directory. This isn't clear and confused me quite a
bit. And it is not compatible with what we need for creating asset
identifiers, which are introduced in the 2nd following commit.
Instead properly determine the complete relative path when initially
adding the file, and don't change it after. The asset identifier can the
be constructed properly at the time needed.
`done` was only used in one place, and `is_updating` was never read.
Generally we should avoid adding this sort of temporary data to longer
lived structs.
