This commit adds a new model to the Sky Texture node, which is based on a
method by Nishita et al. and works by basically simulating volumetric
scattering in the atmosphere.
By making some approximations (such as only considering single scattering),
we get a fairly simple and fast simulation code that takes into account
Rayleigh and Mie scattering as well as Ozone absorption.
This code is used to precompute a 512x128 texture which is then looked up
during render time, and is fast enough to allow real-time tweaking in the
viewport.
Due to the nature of the simulation, it exposes several parameters that
allow for lots of flexibility in choosing the look and matching real-world
conditions (such as Air/Dust/Ozone density and altitude).
Additionally, the same volumetric approach can be used to compute absorption
of the direct sunlight, so the model also supports adding direct sunlight.
This makes it significantly easier to set up Sun+Sky illumination where
the direction, intensity and color of the sun actually matches the sky.
In order to support properly sampling the direct sun component, the commit
also adds logic for sampling a specific area to the kernel light sampling
code. This is combined with portal and background map sampling using MIS.
This sampling logic works for the common case of having one Sky texture
going into the Background shader, but if a custom input to the Vector
node is used or if there are multiple Sky textures, it falls back to using
only background map sampling (while automatically setting the resolution to
4096x2048 if auto resolution is used).

This makes a few changes to the modifier panel header:
1. Adds "move to top" and "move to bottom" buttons.
2. Adds a checkmark icon for "apply"
3. Makes it narrower, the text is closer to the dropdown icon.
(Requires the change in ui_block_func_POPUP)

This includes a few improvments:
1. Always expose delete. This is the button everyone wants the most,
it makes a lot of sense to expose this.
2. Improve "name hiding capability." Basically always align the mode
buttons to the right, and count their number to see if the name fits.
3. Aligns more items, to look better, save space, and make the whole
header seem more grouped.
4. In my tests the "switch contexts" button never coincides with the
delete button, so they share the same space.

If the panel is already open and you ctrl click on its header, its
sub-panels are now expanded / collapsed instead of toggling the
expansion for all other panels. If you're toggling a panel's expansion
it's already in view anyway, so there is no need to collapse the
other panels.

When picking a small tile size when doing a CLI render will
yield many status updates being printed to the console
causing a slowdown in the render process. 2.79 with the
same amount of tiles did not have this slowdown.
The reason for this turned out to be a debugging aid added
in rBd2757d149bf2 which disabled buffering for stdout which
on windows caused every single character being printed to the
console to try to obtain a mutex, and worse the thread being
put to sleep when this mutex was unavailable leading to poor
performance.
This patch changes the behaviour by only disabling the
buffering in debug builds.
CLI render of the default cube with 16x16 tiles at 1080p
2.83 : 37.57s
now : 17.03s
note: this only affected CLI renders, renders from the UI
do not report this kind of information and had no such
slowdown.
Now that we have a uniform consistent behavior in all our ID duplicate
funtions, we can easily factorize it greatly. Code gets cleaner,
smaller, and less error-prone.
Note that ultimately, this duplicate/deep copy behavior could be added
as a callback of IDTypeInfo.
We could also rethink the duplicate flags (some data, even some obdata,
like Lattice, are not coverred currently).
And so on. But at least code should now be much more easily maintainable
and extendable.
Previously, object (and sub-data) actions would be controlled by the
user preferences flag, collections actions would never be duplicted, and
scenes actions were always duplicated...
Now they all follow the user preferences settings.
Main change from user side, besides that all pointers should now be
properly remapped to new IDs, is that linked objects are no longer
preserved when doing a full copy of scenes.
Will open a task to check whether we actually still want that behavior
(and re-code it in a more correct way then).
This is the main part of work done here, it aims at uniformizing and
sanitizing that 'deep copy' process for supported IDs (currently scenes,
collections and objects).
Note that there will be more follow up commits after that one, but this
should be the most risky and changing one.
This resolves T73673 by allowing delete hierarchy in all outliner view
modes. It also unifies the collection and object hierarchy delete into a
single operator like in rBae98a033c856. This makes it easier to delete
all selected collection and object hierarchies at once.
This also removes the old object delete hierarchy code in favor of the
batch delete code which has been default for over a year.

Change how the radius, changing the size of meta plane, sphere & cube.
Previously the size of these primitives would be kept the same,
with only the radius outside the primitive being scaled.
This led to small scale adding a lot of polygons instead
of scaling the primitive down as users would expect.
Also change behavior not to change the resolution when adding
to an existing meta-ball.
Adding volume obdata option to `eDupli_ID_Flags` enum made it go beyond
the 16 bits of a short... Also, enums should typically be stored in
unsigned integers.
Using enum type itself in implementations, and uint in headers (as using
enums types in headers is a pain when enum are not defined and used in a
single same header file...).
It makes no sense to deep-copy a collection and not also copy its
children collections... Parameter was not used anymore anyway.
So now this duplicate function will always at least deep-duplicate all
of its children collections, recursively.
We want to get rid of those for all ID types ultimately, but that one
was only used in one place, being the only one calling
`BKE_collection_duplicate` without hierarchical duplicate and parent
collection pointer, effectively using the full power of the complex deep
duplication code for a mere `BKE_id_copy` call...
This will allow for further cleanup in duplicate code.
This adds the `MultiFunction` type and some smallish utility types that it uses.
A `MultiFunction` encapsulates a function that is optimized for throughput by
always processing many elements at once.
This is an important part of the new particle system, because it allows us to
execute user generated node trees for many particles efficiently.

This patch adds two options:
- Convert a mesh to grease pencil strokes.
- Bake the mesh animation into grease pencil strokes.
Both are related and must be included in the same patch.
Related to tasks: T77629 and T77630
Notice: The conversion is done for mesh edges and it's not considering any visibility clipping. All edges are exported, no matters if it's visible or not.

Some of the files were (indirectly) using dna_type_offsets.h without
adding dependency from bf_dna (which is needed to ensure the file is
generated prior to library compilation).
Now that `BKE_main_collections_parent_relations_rebuild()` is called
from readfile code, we need to make it resilient to potential NULL
master collection pointer in scenes.
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.
Prelimenary step to fix T77460.
Not sure how or when that thing was done, but since that call walks
around collections relationships, it's an utterly critical violation of
liblinking principles (code here should never, ever 'get outside' of its
own ID scope).
This was wroking so far only because code called through this function
(`BKE_collection_parent_relations_rebuild`) was only following parents
pointers (in `BKE_collection_find_cycle()`), which would be either valid
or non-existent.
But next commit is going to change that to also check collection's
objects instancing of other collections.
Lines loose extraction cannot happen on the fly as the render data isn't
complete. This patch will do the lines loose subbuffer extraction as a
simple task and not on the fly.
This patch introduces 2 sub-types of tasks that are executed single threaded.
`EXTRACT_MESH_EXTRACT` would do the extraction using Mesh/BMesh geometry.
`EXTRACT_LINES_LOOSE` creates the `lines_loose` subbuffer from already cached
`lines` IBO.

This is actually a nice issue due to too much optimization...
* Making an ID local just reuse the linked one whenever possible, instead of
actually making a copy of it.
* Therefore, the collection containing that ID is seen as unchanged, since
the pointer itself remained the same.
* But on undo step, there is no way to reuse that local object, which then
gets deleted, and linked one gets re-created - at a different address.
* Collection, however, since unchanged, is not updated at all and thus keeps
reference to the to-be-deleted local object, instead of the linked one.
* Issue gets even worse with viewlayers, this leads to the crash.
To address this, this patch adds a 'virtual' update flags that does nothing
in update case, but will ensure that the affected IDs using the one made local
are properly detected as changed across the relevant undo step.
Note that the recalc flags were chosen mostly for a logical reason, and also
because they are already properly dealt with and cleared by undo code,
so this looks like the optimal solution.
