Combination of two operators by Ares Deveaux
#106524 and #106523
Introduces a new operator "Scale from Neighbor"
that scales selected keyframe segments from either
the left or right keyframe neighbor.
Pressing "D" during modal operation will switch
from which end of the segment the scaling happens.
This is useful to make a section of animation closer to a pose on either side.

I am just finishing it up.
This is a new operator for the Graph Editor.
It shifts the value of the keys in time,
while keeping the actual key positions in the same place.
It supports wrapping, so when offsetting beyond the range
of the F-Curve it will take values from the other end,
but offset in y-value so there is no jump.
This works best with dense key data.

This adds an operator `graph.select_key_handles` to the graph editor
that changes the selection of the different parts of a bezier keyframe. It
operates on all keys that are either themselves selected or have either of
their handles selected, and changes whether the key itself and/or its handles
are selected.
The operator has three options:
- `left_handle_action`
- `right_handle_action`
- `key_action`
Each of which can be set to:
- Select
- Deselect
- Keep (do nothing)

After Renaming "Bake Curve" to "Samples to Keys" in #111049,
the name of the `GRAPH_OT_sample` operator needed renaming.
That is because the word "sample" is now used to describe FCurve
data in an uneditable state.
Rename to `GRAPH_OT_bake_keys` since baking is the term
used in animation to describe the action of creating dense key data.

In the animation transform code, `T_AUTOMERGE` was used
to indicate that the duplicated keys need to be merged.
In perparation of #111051, this no longer makes much sense because
in grease pencil we cannot have two keys in the same channel at the same
frame.
This PR replaces the `T_AUTOMERGE` flag in the animation code to
`T_DUPLICATED_KEYS` to indicate that the transform is being called
with duplicated keyframes.

Breaking change since the operator name changes.
Users have been confused about this for a long time.
The term "bake" in the context of animation usually means
to add keys at a given interval without changing the shape of the curve.
The fact that the curve isn't editable after baking was the main issue.
In order to stop the confusion the operator is renamed to "Keys to Samples"
to indicate that there is a conversion happening and that there are no keys afterwards.
The Un-Bake operator has also been changed to "Samples to Keys"
The operator description has been updated to mention that after the conversion
the data is no longer editable.
The "Bake Sound to F-Curves" has been renamed to "Create Samples from Sound"

Scale the selected key segments to their average
Unlike just scaling using the transform tools, this scales to the average of each individual F-Curve segment.

This is a combination of two PRs from Ares Deveaux: #106521 and #106522
This adds a new operator that allows shearing keys
based on the position of the segment ends.
By pressing `D` while the operator is in modal you can
switch if the operator takes the left or the right segment end as a reference.

Listing the "Blender Foundation" as copyright holder implied the Blender
Foundation holds copyright to files which may include work from many
developers.
While keeping copyright on headers makes sense for isolated libraries,
Blender's own code may be refactored or moved between files in a way
that makes the per file copyright holders less meaningful.
Copyright references to the "Blender Foundation" have been replaced with
"Blender Authors", with the exception of `./extern/` since these this
contains libraries which are more isolated, any changed to license
headers there can be handled on a case-by-case basis.
Some directories in `./intern/` have also been excluded:
- `./intern/cycles/` it's own `AUTHORS` file is planned.
- `./intern/opensubdiv/`.
An "AUTHORS" file has been added, using the chromium projects authors
file as a template.
Design task: #110784
Ref !110783.
This PR blends the selected keyframes to an ease-in or ease-out curve.
The difference to the existing ease slider is that this one blends,
while the other snaps to the ease curve

Implements the Butterworth Filter
(https://en.wikipedia.org/wiki/Butterworth_filter) for smoothing FCurves.
This filter is ideal for smoothing dense data, like motion capture recordings.
It has the advantage of keeping the shape of the curve
intact while reducing minimal fluctuations.
The disadvantage is the impulse response has a twang,
meaning extreme spikes cause fluctuations to either side.
The implementation is based on the GPL code found here:
https://exstrom.com/journal/sigproc/dsigproc.html
In order to avoid phase shifting, the filter is run forward and backward,
effectively doubling the filter order.
The Redo panel offers the following options
* Frequency Cutoff: 0-n value, where 0 means it cuts everything
so the curve will become straight, the max value is the Nyquist frequency
and depends on the frame rate and the "Samples per Frame" option
* Filter Order: Higher values mean the frequency cutoff is steeper
* Samples per Frame: Before the filter is applied, the curve is resampled
at this interval to avoid errors when there are uneven spaces between frames.
If the keys are on subframes, e.g. a 60fps file in a 30fps scene, increase this value to 2
* Blend: 0-1 value to blend between the original curve and the filter result
* Blend In/Out: The number of frames at the start and end for which
to blend between the filtered and unfiltered curve.
This can help reduce any resulting jumps in the animation at the selection border
The operator can be called from the Key menu. (Key->Smooth->Butterworth Smooth)

This moves the remaining `.c` files in the following `editors` folders to C++:
`physics`, `screen`, `sound`, `space_buttons`, `space_file`, `space_graph` and `space_image`.
One exception is `fsmenu.c` which has platform specific issues on macos and
windows. E.g. the `Carbon/Carbon.h` include also declares a `Collection` type that collides
with ours.
Also see #103343.
