It is possible to create scene strips pointing to each other. This is
sanitized when rendering, but in dependency graph such setup will cause
infinite loop.
This patch fixes loop in dependency graph, but same problem exists in

The design for how we approach the "Everything Nodes" project
has changed. We will focus on a different part of the project initially.
While future me will likely refer back to some of the code I remove here,
there is no point in keeping this code around in master currently.
It would just confuse other developers working on the project.
This does not remove the simulation modifier and data block. Those are
just cleaned up, so that the boilerplate code can be reused in the future.
Corrects incorrect usage of contraction for 'it is', when possessive 'its' was required.

The example file in T81218 has a driver that maps a bone's X-location to
the number of BBone segments. This caused a dependency cycle, which
resulted in bad thread serialisation, which caused the crash.
This patch breaks the dependency cycle `BONE_LOCAL` →
`DRIVER(bones["Bone"].bbone_segments)` → `BONE_LOCAL`. The 'Driver Data'
relation now points to `BONE_SEGMENTS` when the driven property starts
with `bbone_`.

Add a dependency graph relation Force Object Animation → Scene Rigid
Body World Rebuild. This ensures that the rigid body world is rebuilt
when a force object is re-tagged for animation updates.
The extra relation doesn't add any new calculations when the animation
is running, as the Time Source node already had a relation to the
scene's `RIGIDBODY_REBUILD` node.
The relation is created directly to the `RIGIDBODY_REBUILD` Operation. I
would have liked to target the containing Component instead. However,
that has the `RIGIDBODY_SIM` operation as entry node, which isn't enough
to actually fix T80121.

Because depsgraph isn't rebuild for animated properies, we have to
assume that active bodies will always want to have updates from the
rigidbody simulation.
We need to have transforms from passive objects if they are animated or
driven by parent relations. This is not immediately obvious as the
object transform matrix will still be available, it is just one frame
behind in some cases.
Fixed dependency cycles if there is a constraint between two rigid
bodies. Because bullet keeps track of its simulated bodies, we do not
need to supply objects transforms as bullet should already have them.
I need combine these two fixes because otherwise we will get depsgraph
warnings that nodes are missing that it expects to be there.

Add a new depsgraph builder class that includes invisible objects and
use that in the Alembic exporter.
Alembic supports three options for visibility, "visible", "inherited",
and "hidden". This means that parents can be hidden and still have
visible children (contrary to USD, where invisibility is used to prune
an entire scene graph subtree). Because of this, the visibility is
stored on the transform node, as that represents the Object in Blender
and thus keeps the Alembic file as close to Blender's own structure as
possible.

The object "delta_" rna variables were not added to the depsgraph search
and thus it would not trigger updates of the object during animation
playback.
This does not fix all the cases in the bug report, because there are multiple
different issues. Only the first two are fixed. The third is probably a known
issue for now.
Before this patch, the rigid body simulation was always done after modifiers
are evaluated, because to perform the simulation, the final geometry of the
object was required. However, the geometry is not required in all cases,
depending on the selected collisions shape.
This patch changes it so that when the simulation does not need the
evaluated geometry, the simulation will be done before the modifiers
are evaluated. This gives the modifiers access to the simulated positions.
When the rigid body simulation does depend on the evaluated geometry,
it will still be performed after modifiers are evaluated.
The simulation will be performed after modifiers are evaluated, iff
the collision shape is "Convex Hull" or "Mesh" and the source is set
to "Deform" or "Final".

This patch adds a new compound shape entry to the shape selection
dropdown. It also corrects wrong inertia calculation for convex hulls,
that resulted in strange behavior for small objects.
The compound shape take the collision shapes from its object children
and combines them. This makes it possible to create concave shapes from
primitive shapes. Using this instead of the mesh collision shape is
often many times faster.

This makes `RNANodeQuery::construct_node_identifier()` more strict in
its matching of certain property names.
The downside of this approach is that it's not possible any more to use
`"rotation"` and expect a match for `"rotation_euler"` and friends, so
the list of strings to test against is now 3x as long.

The extra depsgraph relations that were added to prevent threading
issues during evaluation (rB4c30dc343165) caused a considerable slowdown
on complex scenes with many drivers (T77277, T78615). This commit
improves this as follows.
Only the following drivers are considered for execution serialisation:
- Drivers on Array elements, and
- Drivers on Boolean or Enum properties.
Relations between drivers of the same arrays are added blindly, i.e.
without checking for transitive or cyclic relations. This is possible as
other relations will just target the `PROPERTIES_ENTRY` or
`PROPERTIES_EXIT` nodes.
Checking whether a driver is on an array is first done by checking
`array_index > 0`, and then falling back to resolving the RNA path to an
RNA property and inspecting that.
The code also avoids circular dependencies when there are multiple
drivers on the same property. This not something that is expected to
happen (both the UI and the Python API prevent duplicate drivers), it
did happen in a file (F8669945, example file of T78615) and it is easy
to deal with here.

Comment update
A simulation data block has an embedded node tree, which requires
special handling in a couple of places. Some of those places were
missing beforehand.
This also adds a relation to make sure that the simulation is evaluated
after animations on the embedded node tree are evaluated.
This updates the usage of integer types in code I wrote according to our new style guides.
Major changes:
* Use signed instead of unsigned integers in many places.
* C++ containers in blenlib use `int64_t` for size and indices now (instead of `uint`).
* Hash values for C++ containers are 64 bit wide now (instead of 32 bit).
I do hope that I broke no builds, but it is quite likely that some compiler reports
slightly different errors. Please let me know when there are any errors. If the fix
is small, feel free to commit it yourself.
I compiled successfully on linux with gcc and on windows.
Having a sound strip in the VSE caused a missing relation error to be
logged on the console. This was caused by the AUDIO depsgraph component
not having an entry node. This commits adds that node, and sets up
relations correctly.

This is a fix for c7694185c9. An object without base can still be in the
