commit prior to small refactor

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.

LineArt: Add offset option in object_add.

Sculpt: more brush engine stuff; do not test.

Pushing this commit early due to computer
weirdness

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.

Sculpt: flushed out brush channel RNA and made basic UI

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.
