The code that restored collection flags after they are rebuilt when
moving a collection didn't take into account collection children. The
flag for the active collection was properly restored, but all of its
children would take on the exclude flag of the collection the active
collection was dragged into.
This commit builds a temporary tree structure to store the flags for
the moving collection and its children. Then it reapplies these flags
after `BKE_main_collection_sync`.

This is a follow up commit for rB309c919ee9.
Clearing hash tables is now parallelized as well. Surprisingly, most of
the time is actually spent in `free` (a couple of milliseconds per call
in my test).
Benchmark of individual functions:
reserve_hash_maps: 17%
add_polygon_edges_to_hash_maps: 49%
serialize_and_initialize_deduplicated_edges: 12%
update_edge_indices_in_poly_loops: 14%
clear_hash_tables: 5%
`BKE_mesh_calc_edges` was the main performance bottleneck in D9141.
While openvdb only needed ~115ms, calculating the edges afterwards
took ~960ms. Now with some parallelization this is reduced to ~210ms.
Parallelizing `BKE_mesh_calc_edges` is not entirely trivial, because it
has to perform deduplication and some other things that have to happen
in a certain order. Even though the multithreading improves performance
with more threads, there are diminishing returns when too many threads
are used in this function.
The speedup is mainly achieved by having multiple hash tables that are
filled in parallel. The distribution of the edges to hash tables is based on
a hash (that is different from the hash used in the actual hash tables).
I moved the function to C++, because that made it easier for me to
optimize it. Furthermore, I added `BLI_task.hh` which contains some
light tbb wrappers for parallelization.

- Move some security checks outside of `interp` callbacks.
Namely, that we do get interpolation weights, and have something to
interpolate.
Some callbacks where not checking on those anyway, safer to move that
up into calling code.
- Cleanup usage of sub-weights, lots of interpolation callbacks wher
actually using those completely wrong.
- Change default behavior when no weights are given to higher-level API
functions: prevriously, each callback was responsible to handle that
case (and one did not even do it!), they were switching to purely
additive behavior then.
Instead, we now default to expected simple average of source values.
Note that the only real important change here is defaulting to actual
average of source value when no inertpolation weights are given (afaik,
this only happens in Weld modifier code).

Better use higher-level code from common ID management when possible.
Helps to de-duplicate logic, and reduces outside usages of more
'dangerous' functions.
Note that we could get rid of many of those `BKE_<id_type>_add`
functions now, but on the other hand several of those take extra
parameters and perform additional actions, so think we can keep them all
for now as 'non-standard ID specific creation functions'.
Generic ID management code can now do those local temp copy handling, so
no need for duplicated own code for that.
No behavioral changes expected here.
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.
Note that possibility to pass the new ID pointer as parameter was kept,
as this is needed for some rather specific cases (like in depsgraph/COW,
when copying into already allocated memory).
Part of T71219.
Particularly useful now that we can dynamically generate volume using
modifiers. Not exposed in the user interface currently, but it can be used
by add-ons that need to export an entire scene including volumes.
In the graph editor there is a panel that says "Active Keyframe" for
numerically editing a keyframe's values, but in the code there is no
concept of the "active keyframe." Since this is a useful concept to
have for some other features anyway, this commit adds an active
keyframe index value to FCurves. It also displays it with a theme
color for the active vertex (which didn't exist before) if the
FCurve is active.
The active keyframe in the graph editor is treated similarly to the
active vertex in the 3D view. It is the keyframe most recently selected
with a single click, and it is always selected.
For now, the only real functional change is that the active keyframe
appears in white and it should be more predictable which keyframe is
being edited in the sidebar panel.

Besides the NodeTree case (which remains unchanged), the localize code
is only used in one place (to generate previews of shading data-blocks).
This commit introduces a new `LIB_ID_CREATE_LOCAL` option for ID
creation/copying, which essentially implements the behavior of the
removed `BKE_XXX_localize()` functions into regular mainstream ID copy
code. When this option is set:
- new ID is tagged with `LIB_TAG_LOCALIZED`;
- Some ID copying callbacks have specific behaviors, mainly the root
nodetree of shading IDs gets duplicated with specialized
`ntreeLocalize()` function.
Note that I would not consider getting rid of `ntreeLocalize` for now,
this function is recursive, which should ideally never happen within ID
management copying code (this introduces all kind of complications).
No behavioral change expected from this commit.
Add a specific flag for nodetree deep-copy special localization code.
And add a new `LIB_ID_CREATE_LOCALIZE` flag, similar to
`LIB_ID_COPY_LOCALIZE`, for creation purposes.
No behavioral changes expected here.
When the limit surface is disabled OpenSubdiv generates a set of linear
patches which are only C0 continuous, not C1. This makes it impossible to
evaluate derivatives at vertices which, in this mode, are by definition put
at boundaries of patches. Normals are calculated from those derivatives.
Solution is to disable normal calculation and let it be done downstream, as
for other modifiers. This limitation is also the reason that non feature
adaptive subdivision is badly suited for GPU evaluation.

During the refactor, this feature was removed by error.
When this option is enabled, only the frames with a keyframe are displayed in Draw mode. This is used when fill an animation to paint only in the frames with real drawing.
Apply the De Casteljau algorithm to split the Bèzier curve at the X
coordinate where the new key is inserted, and uses the result to update
both the newly inserted and surrounding handles.
For curves that use Auto keyframes this has been largely addressed by
the new algorithm from D2884. This commit extends this to non-auto
handles.
This code is heavily based on D3172 by Alexander Gavrilov (@angavrilov).

Functionality was hard to follow as the meaning of fullname
depended on basename being NULL or not.
- where_is_temp is now only responsible for finding the temp directory.
- Split out tempdir_session_create into it's own function
that wraps mkdtemp.
- Rename basename to tempdir, fullname to tempdir_session.
These were printf's, disabled by a define that could be uncommented.
Use logging since this can be useful when investigating any issue
with paths not being found at the expected location.
Without this any problem finding app-templates, Python's installation,
icons ... etc are quite difficult to troubleshoot especially on systems
without access to system-call tracing.
To use this run:
blender --log "bke.appdir" --log-level 3
Initialize ImBuf (and color-management) after passing arguments
that set environment variables such as `--env-system-datapath`
This also fixes a bug where BKE_appdir logging failed since it was
called before the `--log` argument was passed.
Add asserts so this doesn't happen again.
Internally appdir functions would test if a path exists,
returning false if it doesn't, leaving the string set instead
of clearing it.
This is error prone as invalid paths could be used accidentally.
Since BKE_appdir_folder_id_user_notest & BKE_appdir_folder_id_version
depend on this, add a 'check_is_dir' argument so the path can be used
even when the directory can't be found.
Change `test_path` function so:
- Joining paths calls a function instead of being performed inline.
- Optional NULL paths must always be ordered last (easier to follow).
Other minor changes:
- Remove FIXME comment is it's handled properly by BLI_path_join.
- The wrong size was being used copying into `targetpath`.
