Fix build error after previous commit

Incorrect renaming and use of enum after search and replace.

Cleanup: Fix/improve variable names and comments

Compositor: Add OIDN prefiltering option to Denoise node

It's equivalent to the OpenImageDenoise prefiltering option in Cycles.
See D12043.

Prefilter modes:
- None: No prefiltering, use when guiding passes are noise-free.
- Fast: Denoise image and guiding passes together. Improves quality when
guiding passes are noisy using least amount of extra processing time.
- Accurate: Prefilter noisy guiding passes before denoising image.
Improves quality when guiding passes are noisy using extra
processing time.

Compositor: Fix crash exporting buffers on debug

ImBuf allocates 4 channels, use copying to support buffers
with 1 and 3 channels.

Compositor: Fix Alpha Over node ignoring emissive colors

It was an issue on Full Frame mode only.

Cleanup: Rename curve node enums

The enum called "interpolate" was really a choice of methods for mapping
inputs to positions on the curve, whereas the "sample" enum was used to
define a way to create a whole set of new points from the curve, without
any input parameters. The "re-sample" vs. "sample" naming makes that
distinction better.

Revert "GPencil: Curvature support for length modifier."

Reason for revert: accidental push of a intermediate change locally.

This reverts commit 25e548c96b3d8c1698fd4385b4dc395665b5a7f6.

GPencil: Curvature support for length modifier.

Audaspace: added audio file streams functionality.

On the blender side this commit fixes importing video files with audio
and video streams that do not share the same start time and duration.

Py API Docs: Fix audio docs example

After new AUD API changes from 2.8x what "buffer" function used to do
has now become "cache" function (it caches a sound into RAM). Therefore,
the basic aud example should call this new "cache" function instead of
"buffer" function.

Thanks to Michael-Z-Freeman for pointing out.

Cleanup: add missing includes

Cleanup: typo

Fix T91461: Pose Library name filter not working

since `AssetHandle` does not have a `name_property`
(`RNA_def_struct_name_property`), and the UIList is just using the
default `uilist_filter_items_default` it simply cannot filter on names
(`RNA_struct_name_get_alloc` wont succeed).

Adding a name_property also wont work since `AssetHandle` inherits
`PropertyGroup` (which already sets name_property).

So this adds a (temporary) hack exception for RNA_AssetHandle in
uilist_filter_items_default until the design of `AssetHandle` progresses
further.

thx @Severin for additional feedback

UI: Always Create Asset Previews

This patch allows Asset Browser previews to be made regardless
of the setting of the (unrelated) "File Preview Type" Preference.

Fix (harmless) mistake in recent new Append code.

This code path is not yet used so no harm, but that was a fairly nasty

Blenlib: introduce a UUID type

Add `BLI_uuid` and `DNA_uuid_types.h` with a UUID implementation
following RFC4122 (https://datatracker.ietf.org/doc/html/rfc4122.html).

The following features are implemented:
- A struct of 128 bits that can be used in DNA definitions.
- Generation of version 4 UUIDs, that is, purely random ones.
- UUID equality function.
- String to UUID and UUID to string conversion functions that are
compatible with RFC4122.
- C++ stream operator that outputs the UUID as string.

This UUID will be used by the asset system, to uniquely identify asset
catalogs.
