This commit adds to ID struct a new optional 'weak reference' to a
linked ID (in the form of a blend file library path and full ID name).
This can then be used on next append to try to find a matching local ID
instead of re-making the linked data local again.
Ref. T90545
NOTE: ID re-use will be disabled for regular append for the time being
(3.0 release), and only used for assets. Therefore, this commit should
not change anything user-wise.

Improve texture painting/uv editing performance when limited scale is active.
Cause of the slow down is that the image editor draws the image in maximum resolution,
but the 3d viewport uses the limited scale. The variation reuses the same GPU texture
and needed to be uploaded/scaled twice to the GPU.
This patch will adds texture slots that can hold the scaled down and the maximum
resolution image. This would allow better cache hits and reuse of existing caches.
Maximum resolution textures are reused for limited scale when they fit to reduce memory
and CPU footprint.

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.
Common investigation together with Jeroen Bakker (@jbakker), thanks. See
also D12242.
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.
Removes the artificial requirement that UDIM tile sets start at 1001.
Blender was already capable of handling sparse tile sets (non-contiguous
tiles) so the restriction around starting at 1001 was unnecessary in
general.
This required fixing a few UDIM-related python bugs around manually
updating the `tile_number` field on images as well. See the differential
for details. No script changes are necessary but they will now work,
correctly, in many more cases.

After looking into task isolation issues with Sergey, we couldn't find the
reason behind the deadlocks that we are getting in T87938 and a Sprite Fright
file involving motion blur renders.
There is no apparent place where we adding or waiting on tasks in a task group
from different isolation regions, which is what is known to cause problems. Yet
it still hangs. Either we do not understand some limitation of TBB isolation,
or there is a bug in TBB, but we could not figure it out.
Instead the idea is to use isolation only where we know we need it: when
holding a mutex lock and then doing some multithreaded operation within that
locked region. Three places where we do this now:
* Generated images
* Cached BVH tree building
* OpenVDB lazy grid loading
Compared to the more automatic approach previously used, there is the downside
that it is easy to miss places where we need isolation. Yet doing it more
automatically is also causing unexpected issue and bugs that we found no
solution for, so this seems better.
Patch implemented by Sergey and me.

With Constrain to Image Bounds selected, UVs will be constrained to the
correct/closest UDIM if the image is tiled.
UVs will be constrained to the 0-1 UV space if the image is not tiled.
This will override the present behavior of always constraining selected
UVs to the 0-1 UV space (UDIM 1001).

This concerns currently only collections (`master_collection` of scenes)
and root node trees. It removes the matching type-specific helpers
(`BKE_collection_master_scene_search` and `BKE_node_tree_find_owner_ID`).
No functional change expected here.
NOTE: Current implementation of `owner_get` is far from optimal, we
could probably do it better, see {T69169}.
NOTE: While it could also have it, shapekeys IDTypeInfo was left out of
this change for now. Mainly because it sould not be used currently, and
we ultimately want to demote shape keys from ID status anyway.
Currently this is needed to properly tag PointCache's for info update
(fixes an issue reported in T82503).
Suspect we may need this in more cases in the future though, RNA
assign/update processes are not always 100% enough to deal with
complicated corner cases.
This patch introduces a partial update of GPUTexture. When rendering
a large image the GPUTexture could have been scaled. The old implementation
would rescale the image on CPU and create a new GPUTexture. This
resulted in flooding the PCI bus.
The new solution would only scale and upload the parts of the GPUTexture
that has been changed. It does this by keeping track of areas of 256x256
pixels. When something changes the tiles that cover that changes will be
rescaled and uploaded the next time the GPUTexture is requested.
Test situation: Default Cube, 4 samples, 19200x10800 tile size 512.
Blender 2.83.9: 4m27s.
Blender 2.91: 20+m (regression)
This patch: 1m01s.
There is still room for more optimizations:
* Reduce the time that an image is locked.
** Use task scheduling to update the tiles of an image.
** Generic optimization of the ImBuf scale method.

Remove DNA headers, using forward declarations where possible.
Also removed duplicate header, header including it's self
and unnecessary inclusion of libc system headers from BKE header.
This commit removes geometry from meshes and shapekeys, and embedded
files, from liboverride IDs.
This data is never overrideable, there is no reason to store extra
useless copies of it in production files.
See T78944.
Note that we may add more data to be skipped on write for liboverrides
in the future, but this commit should address all the most important
cases already.

Image format code checked the file type against an enum except for
zero which is used when the format can't be detected.
Also add doc-strings to some of the image file type callbacks.
This is essentially adding that new callback, and using it only for already
existing Scene's 3DCursor.
Note that the place where this is called has been moved again, after all
have been lib-linked, such that those callbacks may also work on ID pointers.

Those were only shallow wrappers around `BKE_id_copy`, barely used (even
fully unused in some cases), and we want to get rid of those ID-specific
helpers for the common ID management tasks. Also prevents weird custom
behaviors (like `BKE_object_copy`, who was the only basic ID copy
function to reset user count of the new copy to zero).
Part of 71219.
This is part of T76372.
It adds the `blend_write`, `blend_read_data`, `blend_read_lib`
and `blend_read_expand` which correspond to the various
steps when reading and writing .blend files.
Having these callbacks allows us to decentralize the blenloader
code a lot more. This has the affect that code related to any
specific ID type is less scattered.

The abbreviation 'init' is brief, unambiguous and already used
in thousands of places, also initialize is often accidentally
written with British spelling.
This is in order to disolve GPU_draw.h into more meaningful code blocks.
All the Image related function are in `image_gpu.c`.
All the MovieClip related function are in `movieclip.c`.
The IMB module now has a connection with GPU. This is not strickly
necessary and the code could be move to `image_gpu.c` if needed.
The Image garbage collection is also ported to `image_gpu.c`.
A simulation data block has an embedded node tree, which requires
special handling in a couple of places. Some of those places were
missing beforehand.
This also adds a relation to make sure that the simulation is evaluated
after animations on the embedded node tree are evaluated.
For still images, always return 0 for the current frame number. This ensures
Cycles can detects that the image did not change.
