Depsgraph: Special relation for instances and metaballs

Ensures that object which is set for instance-vert or instance-face
is evaluated prior to metaball. This is because metaball will request
list of instances during evaluation.

This should fix issue reported T61431 in release build. The assert is
still there and is to be addressed separately.

Cleanup: Make parent relations a bit cleaner

Mainly getting rid of old and somewhat misleading and unclear
comments.

Fix T61458: GP Ctrl + F doesn't do anything

This keymap was used in the old grease pencil and now must be removed.

The keymaps for brush are:

F: Change Radius
Shift + F: Change strength

Ctrl+F -> Removed.

Modifiers: Make Difference default operation for boolean modifier.

Make Difference a default value for boolean modifier operation property.

Currently operation property of the boolean modifier is set to Intersect, which is the least frequently used boolean operation of the three available. It is also goes out of sync with Intersect (Boolean) tool, where Difference is a default operation.

Depsgraph: Run rigid body after modifiers are ready

This makes it so modifiers are using object transform prior
to the rigid body simulation, and then result of modifier
stack is fed to the solver.

Solves dependency cycle which was happening when object's
modifier was dependent on the modifier transform.

While now it is not possible to change simulation, things
are somewhat more clear and reliable in other ways.
For example previously, solver was using derives mesh from
a previous step in time, which causes unfixable simulation
issues (with intersections and such)

Fixex T61256: Compositing scenes causes crash, but rendering separately does not
Fixes T61262: Armature and rigid body crash
Fixes T61346: Rigid body with modifiers incorrect work

Weight modifiers: Remove weird looking dependency

Modifiers are part of geometry component, no way they can
be dependent on the geometry component of the same object.

Depsgraph: Add utility function for transform dependency

This is what modifiers are to use to indicate that they depend
on a transformation of the object itself.

Currently should be no functional changes, but in the future
this will allow to easily change transform operation depending
on whether there is a simulation associated with the object.

Fix fur on Spring characters

There is an issue of hair being completely messed up when
switching to a simulation view layer for Autumn.

Restoring back the code which was re-setting particles on
file load. This will re-set unbacked particles on file load
but this appears to be happening in 2.7 as well.

Can not reproduce bugs which were fixed in this area recently,
so maybe it's finally tackled (fingers crossed!).

Cleanup: move utility functions into dna_utils

Rename old/new to src/dst since renaming happens in both directions
when versioning.

makesdna: add shared utility module

Currently only a single function was duplicated which isn't so bad,
this change is to allow DNA versioning code to be shared between
dna_genfile.c and makesdna.c.

makesdna: use memarena for string allocations

Include it since versioning code will need to perform
small string allocations too, which doesn't fit will into
the currently used fixed size buffers.

BLI_memarena: remove use of BLI_linklist

Preprare for using memarena w/ makesdna, BLI_linklist depends on
BLI_mempool. Since linked list use in here is simple, do it inline.

Cleanup: use printf define in makesdna

DNA: support versioning structs & struct members

This is only to be used rarely because it's not forwards compatible.

Replace version patching of old 2.80 DNA with a more generic API.

WM: default to opening maximized

Blender is typically used maximized or fullscreen,
load maximized instead of attempting to fill the screen bounds.

To load un-maximized use '--window-border' argument.

Fix T61391: MeshDeform Modifier does not work on a solidified planar mesh.

`BKE_modifier_get_evaluated_mesh_from_evaluated_object()` used by
modifiers needing access to other objects' geometry probably skipped out
of the radar when cage and final evaluated meshes were added to
BMEditMesh? In any case, we do not need to duplicate (and then free!) a
temp mesh from editdata anymore, and we can even add instead a parameter
to get cage instead of final. Also makes modifiers code a bit simpler.
