This just moves the relations update to a lower level function that is used
by other functions. Eventually, the special case for this node should be
generalized.

Ever since the instance domain was added, this was exposed, it just
didn't do anything. This patch implements the instances domain in the
delete and separate geometry nodes, where it acts on the top-level
instances.
We act on a mutable instances input, with the idea that eventually
copy on write attribute layers will make this less expensive. It also
allows us to keep the instance references in place and to do less
work in some situations.

This function node creates a running total of a given Vector, Float, or
Int field.
Inputs:
- Value: The field to be accumulated
- Group Index: The values of this input are used to aggregate the input
into separate 'bins', creating multiple accumulations.
Outputs:
- Leading and Trailing: Returns the running totals starting
at either the first value of each accumulations or 0 respectively.
- Total: Returns the total accumulation at all positions of the field.
There's currently plenty of duplicate work happening when multiple outputs
are used that could be optimized by a future refactor to field inputs.

A few typos in 17770192fb0c5fddda lead to an incorrect count of custom
data layers in the test meshes. We only want to consider layers that are
not anonymous, and there was a copy and paste mistake.

- Use default size consistent with other curve nodes
- Use column instead of row for properties

`GeometrySet::compute_boundbox_without_instances` may not initialize min
max in some cases such as meshes without vertices.
This can result in a Bounding Box with impossible dimensions
(min=FLT_MAX, max=-FLT_MAX).
So repeat the same solution seen in `BKE_object_boundbox_calc_from_mesh`
and set boundbox values to zero.

All these function paramaters are set to NULL so they arent necessary.

Some projects need more than 8-bit RGBA off-screen, so add the ability to
accept color format and defaults to RGBA8 so existing code should not be
affected.
Currently supported formats:
- RGBA8 (default)
- RGBA16
- RGBA16F
- RGBA32F

Blend factor was used to adjust alpha of background image, which is not
correct. This was done in fdee84fd567a where another change was, that
background alpha is copied into result, which is correct.
Apply blend factor to foreground image alpha channel.

The array modifier does not necessarily tag normals dirty.
If it doesnt, normals are recalculated "internally" using the offset ob
transform. This was happening for the array items, but not for the caps.
Now do the same thing for caps.

I had assumed that the span's size was the same as the length variable.
In the future, separate lengths could be removed in favor of using
lengths directly from spans.

Also add file namespace

Fixes two instances of `-Wunused-but-set-variable`
There are several more of these but these were low hanging

Unity build saves 5 seconds off the total build time when compiling `bf_nodes_function`.
Total build times went from 25s to 20s (20% reduction),
tested with ninja on linux running i5 8250U.

Using the output declarations is incorrect because there is a
declaration for each type. Instead loop over the names directly,
since it will make it easier to add an integer mode that only
supports some of the outputs.

The calculation to find the factor between two evaluated points assumed
that the points were not at the same location. This assumption is some-
what reasonable, since we might expect `lower_bound` to skip those
point anyway. However, the report found a case where the first two
evaluated points were coincident, and there is no strong reason not
to make this safe, so add a check for 0 length before the division.

The region used to be type "Channels", but the standard for this
type is "Tools", which is what the file browser uses. This follows
the changes in rB01df48a98394, which also make the region more
"standard."

Some effect functions looped over alternating lines, previously with
different factors. Since only one factor is used, code can be
simplified by looping all lines in one for loop.
There should be no functional changes.

* Assert about source ID of an overridden pointer property not being a
liboverride was not necessary, just skip in that case.
* Tag actual 'real' ID owner for resync, and not (potentially) an embedded one.

2 factor variables were passed to effects, but they were hard coded to
have same value.
Remove duplicate variable from arguments, rename single argument to
`fac`. Inverted factor variables were renamed to `mfac`. Any other
factor related variables are prefixed with `temp_`.
There should be no functional changes.

If the override system creates an override record for the cache
name (no idea why though), it trashes the disk cache on file load.
The reason is that it tries to rename cache files in update handler
when assigning the name, and BLI_rename deletes the target file even
if both names are the same.
This is a safe fix that simply aborts the pointless rename attempt.
