a09d0cfd8c Anim: Move pose bone selection state to bPoseChannel
Move the selection flag for pose bones, from the (edit)bone to the
pose bone.

Previously having multiple instances of armatures in pose mode at the
same time caused issues because selecting a pose bone on one armature
would automatically select it on all instances of it.

This is now fixed since the selection state is stored on the pose bone
(Object level) Doing so breaks API compatibility with 4.5 since the
RNA property on the Bone no longer affects the pose bone. Instead,
there is a new property on the pose bone for that.

Due to this change, some runtime flags for the transform system also
had to be moved to the pose bone. This is due to the fact that these
flags are used by the transform system to pass information between
functions. If we keep the flag at the bone level, this wouldn't work
with armature instances. See `bPoseChannelRuntimeFlag`

bbfc97ad6f Move tests/data and assets to the main repository
This change moves the tests data files and publish folder of assets
repository to the main blender.git repository as LFS files.

The goal of this change is to eliminate toil of modifying tests,
cherry-picking changes to LFS branches, adding tests as part of a
PR which brings new features or fixes.

More detailed explanation and conversation can be found in the
design task.

2d1fc1bcdd Fix #132195: Unable to key mesh attributes
The issue is that certain RNA paths cannot be generated to come
from an ID and `RNA_path_from_ID_to_property` will return no value.
We are using that function in the keyframing code to allow passing
in a pointer to a bone and a path relative to that bone.
Since there is currently no good way to find the path from the ID to an arbitrary
struct pointer (see #122427), this patch is a workaround that uses
the struct_pointer IF that happens to be an ID pointer.
Of course that still has the core limitation in place but until a
better solution is available on the RNA side this is the best we can do.

43d7558e5b Anim: Remove 'Slotted Actions' experimental flag
This commit takes the 'Slotted Actions' out of the experimental phase.
As a result:

- All newly created Actions will be slotted Actions.
- Legacy Actions loaded from disk will be versioned to slotted Actions.
- The new Python API for slots, layers, strips, and channel bags is
  available.
- The legacy Python API for accessing F-Curves and Action Groups is
  still available, and will operate on the F-Curves/Groups for the first
  slot only.
- Creating an Action by keying (via the UI, operators, or the
  `rna_struct.keyframe_insert` function) will try and share Actions
  between related data-blocks. See !126655 for more info about this.
- Assigning an Action to a data-block will auto-assign a suitable Action
  Slot. The logic for this is described below. However, There are cases
  where this does _not_ automatically assign a slot, and thus the Action
  will effectively _not_ animate the data-block. Effort has been spent
  to make Action selection work both reliably for Blender users as well
  as keep the behaviour the same for Python scripts. Where these two
  goals did not converge, reliability and understandability for users
  was prioritised.

Auto-selection of the Action Slot upon assigning the Action works as
follows. The first rule to find a slot wins.

1. The data-block remembers the slot name that was last assigned. If the
    newly assigned Action has a slot with that name, it is chosen.
2. If the Action has a slot with the same name as the data-block, it is
    chosen.
3. If the Action has only one slot, and it has never been assigned to
    anything, it is chosen.
4. If the Action is assigned to an NLA strip or an Action constraint,
    and the Action has a single slot, and that slot has a suitable ID
    type, it is chosen.

This last step is what I was referring to with "Where these two goals
did not converge, reliability and understandability for users was
prioritised." For regular Action assignments (like via the Action
selectors in the Properties editor) this rule doesn't apply, even though
with legacy Actions the final state ("it is animated by this Action")
differs from the final state with slotted Actions ("it has no slot so is
not animated"). This is done to support the following workflow:

- Create an Action by animating Cube.
- In order to animate Suzanne with that same Action, assign the Action
  to Suzanne.
- Start keying Suzanne. This auto-creates and auto-assigns a new slot
  for Suzanne.

If rule 4. above would apply in this case, the 2nd step would
automatically select the Cube slot for Suzanne as well, which would
immediately overwrite Suzanne's properties with the Cube animation.

Technically, this commit:
- removes the `WITH_ANIM_BAKLAVA` build flag,
- removes the `use_animation_baklava` experimental flag in preferences,
- updates the code to properly deal with the fact that empty Actions are
  now always considered slotted/layered Actions (instead of that relying
  on the user preference).

Note that 'slotted Actions' and 'layered Actions' are the exact same
thing, just focusing on different aspects (slot & layers) of the new
data model.

The "Baklava phase 1" assumptions are still asserted. This means that:
- an Action can have zero or one layer,
- that layer can have zero or one strip,
- that strip must be of type 'keyframe' and be infinite with zero
  offset.

The code to handle legacy Actions is NOT removed in this commit. It will
be removed later. For now it's likely better to keep it around as
reference to the old behaviour in order to aid in some inevitable
bugfixing.

Avoid running a Python unit test for layered Actions in non-experimental

Due to a misunderstanding, enabling the user preference for the 'Slotted
Actions' experimental feature is still possible on release builds, which
caused this test to fail on non-experimental builds (because it's
intentionally missing a chunk of experimental code).

d58176e1e0 Anim: fix bug in action.fcurves.clear() corrupting F-Curve groups
Calling `action.fcurves.clear()` would clear the F-Curves, but didn't
update the F-Curve groups. This meant that the groups data still had their
original length & offsets into the F-Curves array, causing subsequent
F-Curve creation to crash Blender.

6ef77a0d22 Anim: Deselect Keys before inserting new keys
This commit changes the keying code to deselect keyframes when inserting new keys.
This has been discussed in the Animation & Rigging module meeting [1].
There is also an RCS post about that [2].
Doing this brings key creation in line with object creation,
where only the newly created object is selected.
There has been a previous attempt [3] to do a similar thing.

### Changes
When inserting keys by pressing `I` in the viewport or choosing a keying set,
all keys of the `Action` get deselected before inserting new keys.
New keys are selected by default.
Python RNA functions are **NOT** affected, meaning addons using
those functions will not deselect any keys by default.
The developer has to choose to do so.
To make that easier, there is a new RNA function on the action
`deselect_keys`

83311ef96d Fix #122777: The keyframe_insert method throws python exceptions
Just for the `pyrna_struct_keyframe_insert()` function, reduce the
reporting level of keyframe insertion failures from `RPT_ERROR` to
`RPT_WARNING`. This prevents the conversion of these reports to a Python
exception.

`CombinedKeyingResult::generate_reports()` now accepts an option
argument `report_level`, so that the caller is in control over the type
of reports it generates.

Previously only errors were converted to exceptions; warnings were
implicitly cleared and never displayed. To avoid these 'keyframe
insertion failure' reports from becoming invisible, the
`pyrna_struct_keyframe_insert()` function now sends any warnings to
stdout (unless there were errors, in which case the old
error-to-exception behaviour is still there).

7fddad529e Fix: keyframe values with additive NLA stack
The new keyframing functions introduced in #113504
didn't call the functions to decompose the NLA stack.

In practice this meant that when inserting keys into strip
that is under an additive strip, it would take the result of the additive Strip and
bake it back into the base. This would double the transform.

The fix is to call `BKE_animsys_nla_remap_keyframe_values`.
Unfortunately to do so, I had to pass through a few more
arguments to the keyframing functions.

Also adds unit tests to cover the caused bug.

afa4391eeb Fix: Issue with Cycle aware keying when inserting second key
Caused by #113504

While basic cycle aware keying works, there is a special case
when inserting the first key. In that case, after the key has been inserted,
it is duplicated and moved around so the FCurve range from
first to last key is exactly the range of the action.
It also auto-creates the Cycle modifier on the FCurve .

Fix the issue by calling the function that does the key duplication
and cover with unit tests.

5e28601d69 Anim: Separate keying flags
Splits the flag `..._FLAG_INSERTNEEDED` between autokey and
manual keying. The fact that this flag was shared between the two
systems has been the cause of issues in the past. It wouldn't
let you insert a keyframe even though you explicitly used an operator
to do so.

In order to be clearer what options are used where, the user preferences
have been reordered.

By default "Only Insert Needed" will be enabled for auto-keying, but not for manual keying.
The versioning code will enable both if it was enabled previously.

# Code side changes

The keying system has flags that define the behavior
when keys are inserted. Some of those flags were shared
between keying and auto-keying. Some were only used for
auto-keying.
To clarify that, prefix flags that used exclusively in one or the other
system with `AUTOKEY`/`MANUALKEY`

Also the flag name on the user preferences and the tool settings was renamed.
Previously it was called `autokey_flag`. To indicated that it is not only used
for autokeying, rename it `keying_flag`.

03a66af318 Anim: Unit tests for "Insert Needed"
Add unit tests for the user preference option "Insert Needed"

Basic tests for objects and bones that check if autokeying in
combination with "Insert Needed" only
* keys all location channels on the first key
* keys only the modified channel on the second key

It is supposed to add only keyframes that have been affected
by the used transform operation.
E.g. translating an object will only add keys on translation keys.

The behavior of keying all property array channels first, and then
only add keys on values that have actually changed may change
in the future. Ideally it would only key actual changes to begin
with. But there is no way to do this right now.

a99e419b6e Anim: Insert keyframes without keying sets
When animators want to key something in the viewport,
the code needs to know *which properties* should be keyed of that selected thing.
So far that was done with keying sets, and a pop-up that let's
you choose the keying set to use. You can get rid of the popup by
choosing a keying set ahead of time. But that is also not always desirable.

That pop-up is quite confusing and gives way too many options.
To simplify this process this PR adds a User Preference option to choose one or more of:
* Location
* Rotation
* Scale
* Rotation Mode
* Custom Properties

Now whenever the `I` key is pressed in the viewport,
and no keying set is enabled, it reads the preferences for which channels to insert.

# User Facing changes
* The popup will not be shown when pressing the hotkey,
 but you can still explicitly use keying sets by going to the menu
* Which channels are keyed is defined by a User Preference setting under animation
* when a keying set is used explicitly, the User Preference settings are ignored
