Use this utility function for render-shading & weight paint modes.
This adds support for edit-mode & pose-mode where all objects in the
mode are used in this case instead of the selected objects.
This was added in 1cb7267a9f, however the behavior before this
would have failed on negative values already.
Also negative values here would fail in many other places.
`ssize_t` is not a standardized type (it's a posix type)
given the line in question here is calculating the size
of a memory allocation there's no logical way this
should ever be negative.
I do not know this code too well and was unsure if
`mdverts->totweight` could ever be < 0, so I protected
it with a clamp, just in case.
Problem is again with the embedded data, we want to make those local
together with their owner ID, but sometimes we are actually dealing with
copies here, which are inheritently already local.
Code did not considered that possibility before, leading to access to a
NULL `lib` pointer.
This should also be back-ported to 2.83 LTS release.

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.

Issue was with our dear posebones again... when applying overrides we
keep the same address/pointer for the IDs themselves, (which avoids us
the need to remap their usages), but their inner data is often
re-allocated.
Therefore, we need once again to go over armature objects and invalidate
their posebone pointers.
This should also be back-ported to Blender LTS 2.83.

This is part of T76372.
It adds the `blend_write`, `blend_read_data`, `blend_read_lib`
and `blend_read_expand` which correspond to the various
steps when reading and writing .blend files.
Having these callbacks allows us to decentralize the blenloader
code a lot more. This has the affect that code related to any
specific ID type is less scattered.

This implements Snake Hook as a deform type for the cloth brush. This
brush changes the strength of the deformation constraints per brush step
to avoid affecting the results of the simulation as much as possible. It
allows to grab the cloth without producing any artifacts in the surface
and create more natural looking folds than any of the other deformation
modes.

In 2.83 and previous versions there was a bug that was causing boundary
vertices to be detected incorrectly that was preventing the smooth brush
to work on boundaries if there was a pole on them.
In 2.90 the boundary vertex detection was fixed, but it was still using a
simplified version of the algorithm without any boundary smoothing. This
patch implements a similar smoothing algorithm to what I think it was
the intention of 2.83 and previous versions, but working correctly.

Since stone age of lib_query, the code would iterate over the current
list of active sequences (from a meta strip e.g.), and not over the
whole list of those.
This is a critical issue as it means in some cases (editing a meta strip
typically), some ID pointers would be missed/ignored by this foreach
looper, which is now at the center of most of our ID management code.
This caused a bug here at the studio, leading to loss of all sound IDs
used by sound strips when editing and undoing inside a meta strip, since
ID refcounting would not happen properly on strips using sounds outside
the meta-strip context during file reading of the undo steps.
To be backported to 2.83.

Split the depsgraph allocation into a separate function
`BKE_scene_ensure_depsgraph()`. Parameters are only passed to those
functions that actually need them. This removes the the "if that boolean
is `false` this pointer is allowed to be `NULL`" logic and more cleanly
decouples code.
No functional changes.
Reduce nesting by flipping conditions and returning early. It's now much
clearer that it's actually a linear function (rather than a nested one).
No functional changes.
For the sanity checks to work we don't actually need to check other
scenes. So this function can be simplified so that it does not require
a `Main *`.
Mistake in 5cc08510e0.
Code dealing with object copy of master collection was bugy in case one
of the new object copy would get a name lesser than the original object,
leading to new copy being inserted before original one in lists.

Allow adding keys outside of the NLA strip, when Sync Length is
activated. Before this, an animator would have to exit tweak mode,
adjust the strip length, then enter tweak mode again.
Now the animator can freely insert and modify keys outside of the strip
bounds. They will never have to touch the strip bounds directly.

Change the way Sync Length works so that it keeps keyframes at the same
key as before the sync. Now when the user exits tweak mode, the overall
NLA result is unchanged.
