Refactors animsys_evaluate_nla() into 2 versions:
animsys_evaluate_nla_for_keyframing(), animsys_evaluate_nla_for_flush()
to make it clear what data is being calculated and why.
Dummy strip creation has been refactored to two separate functions,
animsys_create_tweak_strip() and animsys_create_action_track_strip().
Both are evaluated differently from other strips and eachother. There's
no need to interweave them. A future patch D8296, generally requires
both strips.

XXX anim_sys.c) nlatrack_find_tweaked() is a temporary work around.
If anyone has any insight into this problem, help is appreciated.

This was returning an empty allocated string, however almost
all callers checked if the return value was NULL before freeing,
making for misunderstandings on the intended use of this function.
BCAnimationSampler::initialize_curves for example detected the
f-curves animation type to 'bone' based on a non-NULL return value
which never failed.
Also fixes two leaks where the the result of BLI_str_quoted_substrN
wasn't freed.
- BKE_bezt_subdivide_handles -> BKE_fcurve_bezt_subdivide_handles
- binarysearch_bezt_index -> BKE_fcurve_bezt_binarysearch_index
These functions are specific to F-Curves and don't make sense for other
uses of BezTriple (curve-object data for e.g.)
Also:
- Move detailed doxygen comment above code, following code-style.
- Mark bezt_add_to_cfra_elem unused.
Check selection state in `BKE_fcurve_active_keyframe_index()`, and only
return the active keyframe index when that keyframe is actually selected.
This is now also asserted in the `BKE_fcurve_active_keyframe_set()` function,
which is now also used when inserting a keyframe.
Previously Blender would only match the existing curve slope when the
to-be-inserted key value was already very close to the curve. This check
is now removed, allowing for sliders in the graph editor to subtly
change the curve, and for keyframes added with ctrl+click to follow the
curve better.
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.

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).

Actions are either locked to a specific ID type, or "floating". Actions
in the floating state are now locked when they are assigned to an ID block.
Previously (rB94b99b5d4a7c20cf2) this was done at evaluation time, which
caused various problems:
- The ID type was set on the evaluated copy, and inconsistently flushed
back to the original.
- A newly created Action could not be assigned to an Action constraint,
unless a depsgraph evaluation was be forced first.
This is now resolved by calling `BKE_animdata_set_action()` to set the
action (instead of direct assignment) where possible, and calling
`BKE_animdata_action_ensure_idroot()` otherwise.

Caused by rBfffba2b6530.
In above commit, the buttons rnaindex [-1 for entire arrays like colors]
was not used anymore for the entire function body of
`ED_autokeyframe_property` (previously in `ui_but_anim_autokey`).
Replacing the index with 0 (in the array case) is indeed necessary for
`BKE_fcurve_find_by_rna_context_ui`, prior to rBfffba2b6530 this was
taken care of by using `ui_but_get_fcurve` instead [which did this
internally].
But using an index of 0 (instead of -1) for the entire function body of
`ED_autokeyframe_property` fails for the array part later, namely
`insert_keyframe` needs -1 here.
Now just replace the index for //finding the FCurve//, but use the
original for //inserting the keyframe//.
Could be backported to 2.83 LTS.

Subscribers:
Custom driver functions need access to the dependency graph that is
triggering the evaluation of the driver. This patch passes the
dependency graph pointer through all the animation-related calls.
Instead of passing the evaluation time to functions, the code now passes
an `AnimationEvalContext` pointer:
```
typedef struct AnimationEvalContext {
struct Depsgraph *const depsgraph;
const float eval_time;
} AnimationEvalContext;
```
These structs are read-only, meaning that the code cannot change the
evaluation time. Note that the `depsgraph` pointer itself is const, but
it points to a non-const depsgraph.
FCurves and Drivers can be evaluated at a different time than the
current scene time, for example when evaluating NLA strips. This means
that, even though the current time is stored in the dependency graph, we
need an explicit evaluation time.
There are two functions that allow creation of `AnimationEvalContext`
objects:
- `BKE_animsys_eval_context_construct(Depsgraph *depsgraph, float
eval_time)`, which creates a new context object from scratch, and
- `BKE_animsys_eval_context_construct_at(AnimationEvalContext
*anim_eval_context, float eval_time)`, which can be used to create a
`AnimationEvalContext` with the same depsgraph, but at a different
time. This makes it possible to later add fields without changing any
of the code that just want to change the eval time.
This also provides a fix for T75553, although it does require a change
to the custom driver function. The driver should call
`custom_function(depsgraph)`, and the function should use that depsgraph
instead of information from `bpy.context`.

This addresses warnings from Clang-Tidy's `readability-else-after-return`
rule in the `source/blender/editors/animation` module.
No functional changes.
Functionality here has become confusing over time,
this removes duplicate, similar functions, preferring to set the mode
instead of toggle, enter, exit.
Mode switching utility function behaved differently regarding undo,
'ED_object_mode_toggle' for example didn't skip the undo push
where 'ED_object_mode_set' did.
Some callers chose these functions based on the intended undo behavior,
even when toggling didn't make sense.
There was also ED_object_mode_generic_enter which was similar to
ED_object_mode_set, instead of the reverse of ED_object_mode_generic_exit.
Simplify object mode switching internals:
- Replace ED_object_mode_generic_enter with ED_object_mode_set.
- Remove ED_object_mode_toggle as nearly all callers needed to check
the current mode so toggling would set the mode argument correctly.
- Use ED_object_mode_set for the object mode switching operator
to simplify logic.
- Add ED_object_mode_set_ex which has an argument to disable undo,
needed when loading undo data needs to set the mode.
- Remove unused ED_object_mode_exit.
All the driver-specific code in `fcurve.c` has been moved into a new file
`fcurve_driver.c`. The corresponding declarations have been moved from
`BKE_fcurve.h` to `BKE_fcurve_driver.h`.
All the `#include "BKE_fcurve.h"` statements have been investigated and
replaced with `BKE_fcurve_driver.h` where necessary.
No functional changes.
The `BKE_animsys.h` and `anim_sys.c` files already had a an "AnimData
API" section. The code in that section has now been split off, and
placed into `BKE_anim_data.h` and `anim_data.c`.
All files that used to include `BKE_animsys.h` have been adjusted to
only include the animation headers they need (sometimes none).

Now the area and region naming conventions should be less confusing.
Mostly a careful batch rename but had to do few smaller fixes.
Also ran clang-format on affected files.
Mpving utils from idcode to idtype proved to be somewhat painful for

There are two ways in which adding/deleting keyframes can fail, but only
one of those was handled. The other would be shown as a successful
add/delete of -2 keyframes.
The `ANIM_apply_keyingset()` returns a value that indicates the number of
changed channels (if nonnegative) or an error state (negative). In the
places where the return value was actually used, this value was stored in
a badly named variable.
- Use 'int' for counters instead of short.
- Use 'bool' instead of a counter when only a change is being detected.
- Use typed enum for keying set flags.
- Include in comments when a negate error code may be returned.
- Split 'verify_fcurve' into two functions:
ED_action_fcurve_ensure which adds the f-curve if needed.
ED_action_fcurve_find which returns NULL when not found.
Callers of ED_action_fcurve_find had unused 'group'
argument which has been removed.
- Rename verify_adt_action to ED_id_action_ensure
It had an argument to add data which was always true,
remove this instead of splitting in into a separate function.
The default was changed with an initial implementation of the feature.
With the feedback from animators, having a behavior which affects curves
outside of a changing range is not convenient for professional animators
working on high quality character animation. On the other hand, automatic
smoothing is better for casual animation of object motion.
This change adds an ability to change the default via User Preferences.

The old layout of `PointerRNA` was confusing for historic reasons:
```
typedef struct PointerRNA {
struct {
void *data;
} id;
struct StructRNA *type;
void *data;
} PointerRNA;
```
This patch updates it to:
```
typedef struct PointerRNA {
struct ID *owner_id;
struct StructRNA *type;
void *data;
} PointerRNA;
```
Throughout the code base `id.data` was replaced with `owner_id`.
Furthermore, many explicit pointer type casts were added which
were implicit before. Some type casts to `ID *` were removed.

Use explicit boolean flag to indicate whether flush to original data
is needed or not. Makes it possible to avoid confusion on whether an
evaluated or any depsgraph can be passed to the API.

It was used to access evaluated object and pose and was done prior
to implementation of flushing values back to original data for an
active dependency graph.
Removing the argument allows to simplify API and solve issues with
accessing missing dependency graph on redo.
Expose REPLACE and CYCLE_AWARE, and add AVAILABLE for completeness.
These flags are generic and safe to use, and necessary to match
the behavior of certain UI options.
