Alembic procedural: deduplicate cached data accross frames

Currently the procedural will add an entry to the cache for every frame
even if the data only changes seldomly. This means that in some cases we
will have duplicate data accross frames.

Now we compute a hash for the data and compare it to the one for the
previous frame and only if they are different do we create a new entry.
The hash is computed by the Alembic library (using murmur3).

This can drastically reduce memory usage at the cost of more processing
time. In one file, memory usage goes from 9.08 Gb down to 4.28 Gb over
240 frames.

Cleanup: remove unnecessary `ATTR_FALLTHROUGH`

`ATTR_FALLTHROUGH` is only necessary when there is actually code inside
the falling-through `case`.

No functional changes.

Cycles: optimize ensure_valid_reflection(), reduces render time by about 1%

This is an implementation that is about 1.5-2.1 times faster. It gives a result
that is on average 6� different from the old implementation. The difference is
because normals (Ng, N, N') are not selected to be coplanar, but instead
reflection R is lifted the least amount and the N' is computed as a bisector.

Fix T56925: Cycles banding artifacts in dense volumes

Offset the starting point of segments by a random amount to avoid the bounding
box shape affecting the result and creating artifacts.

Explicitly consider hidden bones as not selected

GPencil: First changes to use evaluated curve data

Still not working

GPencil: Change Armature modifier to refresh curve data

Pose blending: also apply rounding to floats

My code for interpolating booleans basically performed the same function
as the rounding for ints and enums. Now the code is the same, too.

No functional changes

Rough implementation for temp-loading poses from C

The code needs some cleanup, as the temp-loading of asset datablocks needs
to be separated from the pose library code.

Cleanup: pose library, remove unused includes

No functional changes.

Pose library: add simple blending of pose Action onto current pose

Naieve blending of the pose Action onto the current pose. This performs
linear blending (LERP) per FCurve. This is not suitable for rotations, so
it's probably better to do proper matrix interpolation for loc/rot/scale.
However, for other properties, the current LERP will be necessary anyway.

Pose library: Use scrollwheel to set the blend factor

This is not the final UI, but gives a way to at least set it to some value.

Cleanup: remove unused code and rename variables/fields

No functional changes.

Add operator `POSELIB_OT_blend_pose` for interactive pose blending

The operator doesn't blend yet, but it does allow temporarily applying the
pose, switching between the original and the given pose with Tab, applying
the pose with Enter/LeftClick, and cancelling with Esc/RightClick.

Merge branch 'master' into cycles_procedural_api

Fix Cycles rendering crash on OpenBSD

Static initialization order was not guaranteed to be correct for node base
types. Now wrap all initialization in accessor functions to ensure the order
is correct.

Did not cause any known bug on Linux/macOS/Windows, but showed up on this
platform.

LineArt: Continue comment cleanups.
