Trying to open the 2.74 Fishy Cat file would generate endless asserts in
customdata code. This commit refactors and cleans up the code of
`psys_get_dupli_texture` to avoid useless calls and data access, and
validate data before trying to further access it.
No behavioral changes expected here (besides getting rid of the assert).
Relying on pointer addresses across different data-blocks is extremely
not recommended (and should be strictly forbidden ideally), in
particular in direct_link step of blend file reading.
- It assumes a specific order in reading of data, which is not ensured
in future, and is in any case a very bad, non explicit, hidden
dependency on behaviors of other parts of the codebase.
- It is intrinsically unsafe (as in, it makes writing bad code and making
mistakes easy, see e.g. fix in rB84b3f6e049b35f9).
- It makes advanced handling of data-blocks harder (thinking about
partial undo code e.g., even though in this specific case it was not
an issue as we do not re-read neither windowmanagers nor worspaces
during undo).
New code uses windows' `winid` instead as 'anchor' to find again proper
workspace hook in windows at read time.
As a bonus, it will also cleanup the list of relations from any invalid
ones (afaict it was never done previously).

Followup for rB8398050695
This requires moving a few enum definitions to DNA instead of BKE, and
adding default definitions for the two structs the cloth modifier where
the cloth modifier stores its settings. The defaults are also reordered
to be consistent with the order of each item in the struct.
This simulation area mode moves the active area with the brush. When
enabled, the cloth brush has no restrictions on stroke length, area or
mesh vertex count.
In order to work, this enables PBVH nodes dynamically for simulation as
the stroke location moves and builds the constraints for new nodes
during the stroke. When a node is not inside the simulated area, all the
constraints that were created for it and vertex collisions are not
computed. The simulation limits falloff areas and constraints tweaking
control how the simulated and no simulated nodes blend.

The adds a new option to simplify volumes in the viewport.
The setting can be found in the Simplify panel in the render properties.
Volume objects use OpenVDB grids, which are sparse. For rendering,
we have to convert sparse grids to dense grids (for now). Those require
significantly more memory. Therefore, it's often a good idea to reduce
the resolution of volumes in the viewport.

This was already changed for Material nodetrees on duplication in
rBa75ac18638f4.
Since it is not obvious from the UI how change World actions - and to be
consistent with Material actions, it is best to copy the action as the
default behavior.
So use generic BKE_id_copy functions with LIB_ID_COPY_ACTIONS flag [which
also enables us to get rid of `BKE_world_copy`]
Note: taking the User Preference `USER_DUP_ACT` into account here (for
both material and world actions) could be a followup step.

Before this change, when users switch from edit mode to sculpt mode, the
entire mesh would be visible. Even if in the edit mesh mode part of it was
set to invisible.
With this change the visibility is preserved, by creating a separate face set
for the visible and invisible parts of the mesh and setting their initial visibility.
Implementation details: This adds a function to initialize a new Face Set
datalayer taking the current mesh visibility into account which is stored
in the ME_HIDE flag of the vertices.

This took more than a day to fully investigate and understand, one of
the reasons being that the probability of the issue to show up was
extremely low, and subjected to very specific random factors.
Root of the issue is that, in some very rare cases, a newly read ID
might get the exact same memory address as the one it had when the blend
file was saved.
In that case, `BKE_workspace_active_set` would return immediately, since
the pointer to the active workspace would remain unchanged. But that
lead to having an unset NULL active layout pointer, which would crash
when attempting to get e.g. the active screen.
For the record, I ran into this when running a specific build (master
with one flag added to the `LIB_ID_CREATE` ones, with value `1 << 3`),
using a specific set of options (`--background --factory-startup -noaudio`),
and passing the .blend file from T80090 as argument.
Add an option to disable Alembic vertex interpolation.
Bump subversion from 5 to 6.
Alembic stores mesh samples at specific time keys; when a frame in
Blender maps to a timecode between two samples, Blender will interpolate
the mesh vertex positions. This interpolation only happens when the mesh
has a constant topology, but sometimes this was not detected properly
when the vertices change order, but the number of mesh elements remains
the same. This would result in a mesh with jumbled up vertices (T71981).
With this patch, users have the ability to disable vertex interpolation.
An alternative would be to have better detection of topology changes,
but that that'll cause a considerable slowdown.

Actions are either locked to a specific ID type, or "floating". Actions
in the floating state are now locked when they are assigned to an ID block.
Previously (rB94b99b5d4a7c20cf2) this was done at evaluation time, which
caused various problems:
- The ID type was set on the evaluated copy, and inconsistently flushed
back to the original.
- A newly created Action could not be assigned to an Action constraint,
unless a depsgraph evaluation was be forced first.
This is now resolved by calling `BKE_animdata_set_action()` to set the
action (instead of direct assignment) where possible, and calling
`BKE_animdata_action_ensure_idroot()` otherwise.

We can only re-apply overrides fron the old local overrides to the newly
generated ones after all IDs have been properly remapped and renamed.
Otherwise override operations based on ID names may fail.
Related to T81059, found while investigating it.
Part of the code handling deletion of old, not needed anymore local
override IDs, was not working properly, effectively only deleting one
ID ever.
New code should also be a bit faster, though this should not be really
visible from user perspective.
Related to T81059, found while investigating it.
Root of the issue is how we generate the storage ID for the differential
override operations.
However, since those are disabled anyway currently, simply comment out
creation of this copy for now, we can revisit this if/when we decide to
re-activate differential overrides.

Before we would continue checking normal array values even if we knew

In very rare occations, the returned derivates would be the same. This
would lead to the normal calculation breaking (zero normals).

Do not escape flow / effector objects if they have a disabled use flow / use effector flag.
Vertex velocities still need to be kept track of in order to have correct object velocities when enabling flows / effectors intermittenly. It is possible though to skip the emission loop if the flags are disabled.
This code is not used by the new fluid simulation system.
Therefore, it does not make sense to keep it around.
We do want to integrate the fluid system with the generic cache
system eventually, but refactoring the system is easier when there
is less dead code that has to be refactored.
Note, I could not remove BKE_ptcache_id_from_smoke entirely yet,
because the depsgraph seems to expect that object that
uses DEG_add_collision_relations also has a pointcache.
That is because it wants to reset the point cache when any of the
other objects changed (this does not work with fluids currently).
