A buffer is a technical term most often referred to using the metaphor
of a "clipboard" in applications. However, the "clipboard" is usually
the system clipboard, used to carry data accross applications. To
avoid confusion, this replaces "clipboard" by "internal clipboard"
when not dealing with the system clipboard.
In addition, a few places still used the "[copy/paste] buffer"
terminology, so they are replaced with "internal clipboard as well.
The replacement from "[copy/paste] buffer" to "clipboard" was
undertaken in previous commits da6d6f99a8, 14b60c3a1c. This
commit should tackle the remaining occurrences.

The insert key operator allowed to insert a keyframe on all selected FCurves
and on the Active FCurve at cursor value.
But it didn't allow to insert a keyframe only on the active FCurve.
This patch adds that. It is available in the redo panel and under Key->Insert Keyframes (which can also be called with the I hotkey)

The goal is to solve confusion of the "All rights reserved" for licensing
code under an open-source license.
The phrase "All rights reserved" comes from a historical convention that
required this phrase for the copyright protection to apply. This convention
is no longer relevant.
However, even though the phrase has no meaning in establishing the copyright
it has not lost meaning in terms of licensing.
This change makes it so code under the Blender Foundation copyright does
not use "all rights reserved". This is also how the GPL license itself
states how to apply it to the source code:
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software ...
This change does not change copyright notice in cases when the copyright
is dual (BF and an author), or just an author of the code. It also does
mot change copyright which is inherited from NaN Holding BV as it needs
some further investigation about what is the proper way to handle it.

Add a Gaussian smoothing operator to supersede the current
smoothing operator in the graph editor.
Advantage over the current implementation:
* Supports modal operations
* Is independent of key density
* More options in the redo panel
* More predictable Impulse Response
Option in the redo panel to change
Filter Width: How far out on each side of a key the code checks
to average key values
Sigma: The shape of the bell curve, lower values make a sharper bell curve
reducing the smoothing effect.
Too High values will make the code behave like an average filter as the
curve in the -1/1 range will almost be flat.
On a technical note, the operator needs to store additional data when running in modal
to avoid allocating/deallocating data on every modal run.
For that reason the `tGraphSliderOp` struct has been extended with
`void *operator_data` and `void (*free_operator_data)(void *operator_data)`.
The former is the data and the latter is a function responsible for freeing that data.

In most places where it appears in a menu, the operator would already
apply to all selected F-Curves. Now it is done consistently and explicitly
from all menu items. The default of the operator is now also set to 'all
selected', so that it also behaves like that when called from the operator
search menu.
Refactor the following functions and cover with tests
* `BKE_fcurve_calc_bounds` - used to get the `rctf` bounding box of an fcurve
* `BKE_fcurve_calc_range` - used to get only the x-range, potentially faster when not needing y extents
`get_fcurve_end_keyframes` has been replaced with `get_bounding_bezt_indices` - dealing with indices allows to iterate over that range later
### BKE_fcurve_calc_bounds
* pass in an `rctf` instead of float pointers
* extract logic to get bounds into separate functions
### BKE_fcurve_calc_range
* removed the parameter `do_min_length` it was always false, and this function shouldn't concern itself with clamping.
Calling code can do that if the return bool is false
* use function to get x bounds separated from `BKE_fcurve_calc_bounds`

Drivers: Introduce the Context Properties
The goal: allow accessing context dependent data, such as active scene camera
without linking to a specific scene data-block. This is useful in cases when,
for example, geometry node setup needs to be aware of the camera position.
A possible work-around without changes like this is to have some scene
evaluation hook which will update driver variables for the currently evaluating
scene. But this raises an issue of linking: it is undesirable that the asset
scene is linked to the shot file.
Surely, it is possible to have post-evaluation handler to clear the variables,
but it all starts to be quite messy. Not to mention possible threading
conflicts.
Another possibility of introducing a way to achieve the goal is to make it so
the dependency graph somehow parses the python expression where artists can
(and already are trying to) type something like:
depsgraph.scene.camera.matrix_world.col[3][0]
But this is not only tricky to implement properly and reliably, it hits two
limitations:
- Currently dependency graph can only easily resolve dependencies to a RNA
property.
- Some properties access which are valid in Python are not considered valid
RNA properties by the existing property resolution functions:
`camera.matrix_world[3][0]` is a valid RNA property, but
`camera.matrix_world.col[3][0]` is not.
Using driver variables allows to have visual feedback when the path resolution
fails, and there is no way to visualize errors in the python expression itself.
This change introduces the new variable type: Context Property. Using this
variable type makes allows to choose between Active Scene and Active View
Layer. These scene and view layer are resolved during the driver evaluation
time, based on the current dependency graph.
This allows to create a driver variable in the following configuration:
- Type: Context Property
- Context Property: Active Scene
- Path: camera.matrix_world[3][0]
The naming is a bit confusing. Tried my best to keep it clear keeping two
aspects in mind: using UI naming when possible, and follow the existing
naming.
A lot of the changes are related on making it so the required data is available
from the variable evaluation functions. It wasn't really clear what the data
would be, and the scope of the changes, so it is done together with the
functional changes.
It seems that there is some variable evaluation logic duplicated in the
`bpy_rna_driver.c`. This change does not change it. It is not really clear why
this separate code path with much more limited scope of supported target types
is even needed.
There is also a possible change in the behavior of the dependency graph: it
is now using ID of the resolved path when building driver variables. It used
to use the variable ID. In common cases they match, but when going into nested
data-blocks it is actually correct to use relation to the resolved ID. Not sure
if there was some code to ensure that, which now can be resolved. Also not sure
whether it is still needed to ensure the ID specified in the driver target is
build as well. Intuitively it is not needed.

The active window was used by the NLA and the Graph editor however
this is not always available and not necessarily the window that
contains the area being initialized. Potentially causing the graph and
NLA spaces to be initialized with the wrong scene.
Active window access caused various awkward fixes in the past
([0], [1], [2]) which worked around the active window not being set.
Use a lookup for the window instead of accessing the active window.
Note that passing the window is an option too however this is only
used for versioning older files and is not be needed in most cases.

Fix a crash when using the Euler Filter from the Graph Editor on baked curves.
The crash happened because baked curves have no bezt array.

`bAnimContext` had a float property called `yscale_fac` that was used to define the height of the keyframe channels.
However the property was never set, only read so there really is no need to have it in the struct.
Moreover it complicated getting the channel height because `bAnimContext` had to be passed in.
Speaking of getting the channel height. This was done with macros. I ripped them all out and replaced them with function calls.
Originally it was introduced in this patch: https://developer.blender.org/rB095c8dbe6919857ea322b213a1e240161cd7c843

Remove some assumptions that an FCurve with a single keyframe always is
extrapolated in constant fashion. There's no reason for the Beziér handles
to be ignored in such a case.
FCurve evaluation already worked properly, it was just the drawing in the
graph editor and the selectability of the handles that needed adjustments.
These warnings can reveal errors in logic, so quiet them by checking
if the features are enabled before using variables or by assigning
empty strings in some cases.
- Check CMAKE_THREAD_LIBS_INIT is set before use as CMake docs
note that this may be left unset if it's not needed.
- Remove BOOST/OPENVDB/VULKAN references when disable.
- Define INC_SYS even when empty.
- Remove PNG_INC from freetype (not defined anywhere).

Use recently introduced BKE_fcurve_merge_duplicate_keys (that was moved
from the transform system to BKE) to merge keyframes on the same frame
after snapping (same as what would happen with the transform system).
This makes behavior consistent and prevents a state after snapping that
cannot be reproduced in any other way.
NOTE: same probably has to be done for greasepencil, but that is for
another commit.
The Equalize Handles and Snap Keys operators would allow the user to
invoke them successfully even when they would have no effect due to
there not being any selected control points.
This patch makes it so that an error is displayed when these operators
are invoked with no control points are selected.
The reason this is in the `invoke` function is because it would be too
expensive to run this check in the `poll` function since it requires a
linear search through all the keys of all the visible F-Curves.

Before the fix, the "Remove" (i.e., `factor`) slider was visible no

Change the behaviour of circle select on FCurves:
- Before any key is touched, the behaviour is as it was (key included in
circle-select area → select it; otherwise → select entire curve)
- If any key has been touched, an internal option
(`use_curve_selection`) is flipped and selecting the entire curve is
disallowed.
This ensures that once a key changes selection state, it's no longer
possible to select the entire curve. This allows dragging over keys and
subsequently drag over a keyless part of the curve.

The operator did not set the any extrapolation mode of the individual
keyframes, it sets it for the whole f-curve. Change the operator name to
reflect that.
The only difference between `GPU_SHADER_2D_LINE_DASHED_UNIFORM_COLOR`
and `GPU_SHADER_3D_LINE_DASHED_UNIFORM_COLOR` is that in the vertex
shader the 2D version uses `vec4(pos, 0.0, 1.0)` and the 3D version
uses `vec4(pos, 1.0)`.
But VBOs with 2D attributes work perfectly in shaders that use 3D
attributes. Components not specified are filled with components from
`vec4(0.0, 0.0, 0.0, 1.0)`.
So there is no real benefit to having two different shader versions.
