On file read we need to update group nodes in case the group they refer to
has changed its inputs and outputs. This had O(n^2) time complexity and was
updating all datablocks even if they did not change.
Node versioning code was added before there was a mechanism to do versioning
after lib linking. Now integrate with that system and make it less of a strange
exception. Node versioning is now skipped on undo, like other versioning code.
Allows to preserve topology cache even when copy-on-write is
fully re-copying the object. For example, toggling edit mode
in and out does no longer causes full topology to be re-created.
This is just not practical to do for the code as a whole, and having it as an
exception for one specific data structure is not that helpful. This has only
been in the way for me when refactoring code.
Using GP_BRUSH_MATERIAL_PINNED to switch between active material and brush material, instead of updating all brushes on active material changes. This will allow brushes to have no material and therefore to not inflate the user count.
This fix T62465.

This commit does not add anything new from user perspective, but make it
possible to paste any kind of IDs, not only objects/collections.
Will be used by new copy/paste in the outliner in next commit.
The issue was caused by mesh needed for dynamic paint brush being
stored in the modifier. That make it to be freed and set to NULL
when running copy-on-write.
Solved by moving the mesh to be stored in modifier's runtime data.
The first part of this patch is just a way to improve performance a bit
by not calling BKE_scene_object_base_flag_sync_from_base() twice.
The second is the proper fix for the reported issue.
That said, the report can be re-opened since there is still discussion
about whether or not to bring the collections with the objects.

When copy/pasting an object in same .blend file, orig object would be
instantiated into the active collection when pasting, along with the
content of the paste. Was missing a clear of LIB_TAG_DOIT on objects...
Found while investigating T61670.
Regression in 358e07f447 for ms-windows since off_t is an int32_t
even on 64bit systems causing files over 2gb not to load.
Poison off_t so this doesn't happen again.
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).

T62570 and T61796 show that we need two slightly different behaviors in
post-linking collection process:
* For linking, we never want to instantiate indirectly-linked
collections or objects.
* For appending however, since all collections and objects will become
local and hence need instantiation, we want to 'link to scene' all
collections first, better than instantiating the objects in the master
collection opf current scene.
The shaders are: `GPU_SHADER_3D_FLAT_SELECT_ID` and `GPU_SHADER_3D_UNIFORM_SELECT_ID`.
This commit allows the drawing of the mesh select ids to be done on a 32UI format texture.
This simplifies the shader that previously acted on the backbuffer and had to do an uint to rgba conversion.

Make sure we don't reallocate arrays in the pointcache when not needed, the
size of a memory allocation can be slightly bigger than the requested size.
Also, use consistent check for shared cached in copy and free functions.
Convention was not to but after discussion on 918941483f we agree its
best to change the convention.
Names now mostly follow RNA.
Some exceptions:
- Use 'nodetrees' instead of 'nodegroups'
since the struct is called NodeTree.
- Use 'gpencils' instead of 'grease_pencil'
since 'gpencil' is a common abbreviation in the C code.
Other exceptions:
- Leave 'wm' as it's a list of one.
- Leave 'ipo' as is for versioning.
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).

Do not force to link indirectly linked collections into current scene,
that is usually not desired. Note that user can always add this link
manually if they want.
All this 'implicit instantiation' post-linking process is rather hairy
to get it correct, hope this time it's not breaking something else...
Use 'size' instead of 'len' to represent the size of data in bytes,
'len' is used for the result of 'strlen' or the length of an array
in some parts of 'makesdna.c' & 'dna_genfile.c'.
Also clarify comments and some variable names, no functional changes.
Now always refresh when the material changes. Depsgraph tag moved out
of the refresh function since that gets called on depsgraph update,
which should not trigger a second depsgraph update.
