This is part of a greater blenloader decentralization effort (T76372).
For modifiers the goal is that fewer files have to be modified when
a new modifier is added.
This patch just adds the `blendWrite` and `blendRead` callbacks to
`ModifierTypeInfo` but does not change any other code yet. In the next
steps, modifier specific code will be moved from `writefile.c` and
`readfile.c` into their corresponding `MOD_*` files.
This patch implements the list panel system D7490 for modifiers.
It also moves modifier drawing to a callback in ModifierTypeInfo
in line with the extensible architecture refactoring goal T75724.
This adds a PanelRegister callback and utilities for registering
panels and subpanels. It also adds the callbacks for expansion saving
and drag and drop reordering described in D7490.
These utilities, callbacks, and other common UI elements shared
between modifiers live in MOD_ui_common.c.
Because modifier buttons are now in panels, we can make use of
subpanels for organization. The UI layouts also use the single
column layout style consistently used elsewhere in Blender.
Additionally, the mode-setting buttons are aligned and ordered
consistently with the outliner.
However, the large number of UI changes in this patch may mean
that additional polishing is required in master.
Thanks to William Reynish (@billreynish) who did a fair amount of the
layout work and to Julian Eisel (@Severin) for consistent help.

There is no user visible difference in standard builds, as there are no
volume modifiers yet. When using WITH_NEW_OBJECT_TYPES some deform only
modifiers are now available for hair and pointcloud objects.

Give pointcaches a proper path function which e.g. also resolves
ALT+click (assign to all selected) not working for anything relating to
pointcaches.
This also cleans up the usage of the 'eModifierTypeFlag_UsesPointCache'
flag (removed from the boolean modifier, added to the softbody modifier).

- Use 'BKE_object_material_*', 'BKE_id_material_*' prefix
for functions that operate on Object and ID types.
- Use '_len' suffix for length (matching BLI naming).
- Use '_p' suffix for functions that return a pointer to values
where the value would typically be returned.
Functions renamed:
- BKE_object_material_resize was BKE_material_resize_object
- BKE_object_material_remap was BKE_material_remap_object

- BKE_id_material_clear was BKE_material_clear_id
Modifier stack evaluation would copy mesh settings other than mesh topology
automatically, outside of the individual modifier evaluation. This leads to hard
to understand code, and makes it unclear which settings are available in following
modifiers, and which only after the entire stack is evaluated.
Now every modifier is responsible to ensure the mesh it outputs preserves materials,
texture space and other settings, or alters them as needed.

This is a continuation of rB39f005eae8eed8b939579aff8c9a05a4f50e5e38
Now all the fields where we check for object type in RNA (like
rna_Curve_object_poll) will have a safe guard for when this isn't the
case. For example when loading files that has missing object libraries
and all missing objects are replaced with empties (placeholders).

This was wrong and violating design to force modifiers to query
evaluated objects and IDs. It is up to the caller to make sure
the object is properly evaluatable.
Effectively, reverting changes from de491abf99 (and possibly
other related changes).
The general idea of this change is to have a runtime data pointer
in the ModifierData, so it can be preserved through copy-on-write
updates by the dependency graph.
This is where subdivision surface modifier can store its topology
cache, so it is not getting trashed on every copy-on-write which
is happening when moving a vertex.
Similar mechanism should be used by multiresolution, dynamic paint
and some other modifiers which cache evaluated data.
This fixes T61746.
Thing to keep in mind, that there are more reports about slow
subdivision surface in the tracker, but that boils down to the
fact that those have a lot of extraordinary vertices, and hence
a lot slower to evaluated topology.
Other thing is, this speeds up oeprations which doesn't change
topology (i.e. moving vertices).

We already have different storages for cddata of verts, edges etc.,
'simply' do the same for the mask flags we use all around Blender code
to request some data, or limit some operation to some layers, etc.
Reason we need this is that some cddata types (like Normals) are
actually shared between verts/polys/loops, and we don’t want to generate
clnors everytime we request vnors!
As a side note, this also does final fix to T59338, which was the
trigger for this patch (need to request computed loop normals for
another mesh than evaluated one).

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.

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.
`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.
Turns out most of our 'local working copy' cases can use same set of
flags.
Note that this commit adds LIB_ID_COPY_CACHES to all our local meshes
copying, however this is no-op since that flag is unused during mesh
copying... We may want to add another set of flags without that one at
some point, but for now it would not be useful imho.
BF-admins agree to remove header information that isn't useful,
to reduce noise.

Fix T58237: Exporters: Curve Modifier not applied when "apply modifiers" are selected.
Fix T58856: Python: "to_mesh" broken in 2.8.
...And many other cases... ;)
Thing is, we need target IDs to always be evaluated ones (at least I
cannot see any case where having orig ones is desired effect here).
Depsgraph/Cow system ensures us that when modifiers are evaluated by it,
but they can also be called outside of this context, e.g. when doing
binding, or object conversion...
So we need to ensure in modifiers code that we actually are always
working with eval data for those targets.
Note that I did not touch to physics modifiers, those are a bit touchy
and rather not 'fix' something there until proven broken!
Need to use the 'use_partial_connect' option in island connect,
so changed signatures of various functions to pass that into and
then down from BM_mesh_intersect (making true for intersect, false
for boolean).
Then fix bm_face_split_edgenet_partial_connect to work when
input edges are not necessarily wire, but at least not in the
face they are being connected in. That caused generalization
of core BM_vert_separate_hflag_wire (which is only used in
this one place in all Blender).
Modifiers stack only get COW/evaluated IDs, so no need to go auery again
DEG for those. Further more, now unified handling of EditBMesh case (was
done on case-by-case basis in a few modifiers, not all for some reason).
We are still missing the ability to get final and cage deformed meshes
when in Edit mode though, this is to be defined/implemented in depsgraph.
This fix applying the following modifiers:
* Boolean (working already)
* Array
* Mesh Deform
* Surface Deform
* Vertex Weight Proximity
This function was to return evaluated mesh. So it should get the evaluated
object at all times. So in this case it makes more sense to simply pass the
depsgraph (or in this case the ModifierEvalContext that contains both the
depsgraph and the flag.
Solution discussed with Bastien Montagne.
