The multi-function network system was able to compose multiple
multi-functions into a new one and to evaluate that efficiently.
This functionality was heavily used by the particle nodes prototype
a year ago. However, since then we only used multi-functions
without the need to compose them in geometry nodes.
The upcoming "fields" in geometry nodes will need a way to
compose multi-functions again. Unfortunately, the code removed
in this commit was not ideal for this different kind of function
composition. I've been working on an alternative that will be added
separately when it becomes needed.
I've had to update all the function nodes, because their interface
depended on the multi-function network data structure a bit.
The actual multi-function implementations are still the same though.
Several pure runtime data in this ID type were not properly cleared by
write/read processes.
Note that the initial undo step (the one leading back to initial read
file state) is still forcing re-load of image, for some reasons.

This was partially broken with {rBde9ea94fc6f}.
The `Frame Step` and `Second Step` snapping options were working as if
they were `Nearest Frame` and `Nearest Second` respectively in the
`Dope Sheet` and `NLA` editors.
In the `Graph Editor` the problem was more serious:
"Second Step: ... The keyframe itself moves along as though in snapping
were active at all, while its handles 'stay behind' until it reaches
the next second boundary, at which point the teleport handles to
'catch up'".
The snapping code for these modes was spread across the transform
mode code and `recalcData` of each data type. Therefore, create a
unified snapping code for these options so that all issues are fixed in
one place.

`td2d->loc`, `td2d->loc2d`, `td->loc` and `td->iloc` were not being
initialized as is done with the other conversion types.
This avoids problems with transform modes becoming incompatible.
This avoids problems with incompatible transform modes that could
result in a crash.
This was not really useful, and added estra useless steps in case and ID
should not actually be written.
Further more, it prevented clearing the usercount on write, which can be
cause a false positive 'chanhged' detection in undo/redo case.
This patch exposes the Cycles Alembic Procedural through the MeshSequenceCache
modifier in order to use and test it from Blender.
To enable it, one has to switch the render feature set to experimental and
activate the Procedural in the modifier. An Alembic Procedural is then
created for each CacheFile from Blender set to use the Procedural, and each
Blender object having a MeshSequenceCache modifier is added to list of objects
of the right procedural.
The procedural's parameters derive from the CacheFile's properties which are
already exposed in the UI through the modifier, although more Cycles specific
options might be added in the future.
As there is currently no cache controls and since we load all the data at the
beginning of the render session, the procedural is only available during
viewport renders at the moment. When an Alembic procedural is rendered, data
from the archive are not read on the Blender side.
If a Cycles render is not active and the CacheFile is set to use the Cycles Procedural,
bounding boxes are used to display the objects in the scene as a signal that the
objects are not processed by Blender anymore. This is standard in other DCCs.
However this does not reduce the memory usage from Blender as the Alembic data
was already loaded either during an import or during a .blend file read.
This is mostly a hack to test the Cycles Alembic procedural until we have a
better Blender side mechanism for letting renderers load their own geometry,
which will be based on import and export settings on Collections (T68933).

The current behavior of the Alembic importer is to only create a
`MeshSequenceCache` modifier or a `Transform Cache` constraint to imported
objects if they have some animated properties.
Since static objects do not have a cache reader, when reloading files those
objects are not updated. Currently, the only way to properly reload a file
because of this is to reimport it.
This adds an option to the importer to always add a cache reader, even if
there is no animated data, to ensure that all objects coming from Alembic
archive are linked to them and updated properly upon reloads.

This patch removes the "Kerning Style" option for UI widget font
drawing and uses only the current default of "Fitted", since the other
option of "Unfitted" is just the result of truncation errors.

Again this is only for sake of sane ID/overrides managment for now,
the nodetrees themselves are not overridable from user PoV yet.
This reverts rB6899dbef77cd and makes the pointer explicitely
processable by override & diffing code.
Previous changes & fixes have fixed the 'driver-workaround' case afaict.
Note that this only enables proper generic handling of overrides and
their ID pointers, no node property is actually overridable currently.
Embedded IDs (root nodetrees, master collection, etc.) pointer itself is
not editable, but their content may be overridden.
LibOverride code is supposed to know how to handle those embedded IDs.
This should be a no-change commit for now, but is required to enable
initial basic support of nodetrees in library override.
NOTE: Proper full support of liboverrides in nodes is yet to be designed
(has UX unresolved issues, since we likely do not want to expose/make
overridable ALL settings of ALL nodes).
This code checks whether an ID pointer property of an override does not
match its linked reference when it is expected to do so.
This is a goiod indication that a resync is needed.
Previous code would falsy detect overrides of IDs referencing themselves
as needing a resync, when this is not effectively the case.
Caused by {rBbbb1936411a5}.
When adding strips via the new SEQ_add_XXX_strip functions, the
`Editing->seqbasep` pointer was passed around.
Following in `seq_add_generic_update` this `seqbasep` pointer was used
to ensure a unique name.
But `seqbasep` is the pointer to the current list of seq's being edited
(**which can be limited to the ones within a meta strip**).
We need unique names across all strips though (since these are used for
RNA paths, FCurves as reported), so now use the scene's `Editing-
>seqbase` (**which is the list of the top-most sequences**) instead.
Unfortunately this might have screwed files to a borked state, not sure
if this could easily be fixed...
