Merge branch 'blender-v2.91-release'

Fix T82488: Mantaflow - force fields have very low influence compare to 2.90.1

Removed 0.2f factor when setting forces. Why this factor has been used when forces should only be clamped, nobody knows ..

Fix T82210: Animation, Bake Action cleanup

Make post-bake cleanup of the Bake Action operator optional, and disable
by default.

Previously Bake Action would do two things:
- Bake the Action
- Clean up the FCurves

It is now possible (and even the default) to only perform the baking
operation.

Cycles: Fix tricubic sampling with NanoVDB

Volumes using tricubic sampling were producing different results with NanoVDB compared
to dense textures. This fixes that by using the same tricubic sampling algorithm in both
cases. It also fixes some remaining offset issues and some minor things that broke OpenCL
kernel compilation on NVIDIA.

Libmv: Fix warning about unused parameter in Ceres

Ceres is an external library, so consider it a system header which
makes it so all strict flags are properly ignored for them.

Animation: move group colors switch to user preferences

Move the "Show Group Colors" toggle from a per-editor option to a single
user preference in the Animation preferences. The Grease Pencil
animation channel side panel allows picking a channel color; this now
shows a message when channel colors are disabled.

The old "Show Group Colors" toggle had to be set per editor, and was on
by default. This meant that disabling group colors would require an
action for every file, for every editor. It is very hard to select a
color that works both as bone color in the 3D Viewport (needs to be
bright there) as well as the channel list (needs to be dark there), most
animators turn channel list colors off.

Cleanup: Sequencer, remove unused function

Remove `static int clear_scene_in_allseqs_fn(...)`. It was a utility

in c063813c30e55ddc8f42ef7632d9dfa109dfddff.

No functional changes.

Revert "Fix T80742: curve bevel fails with zero length handles at end-point"

This reverts commit 4987b7d347a885916916a888c18401ea2fe552f4.

This introduced a slight change in curve direction at end-points
(while correct), it caused tests to fail.

Keep this change for 2.92, revert for 2.91.

Fix T82495: assert with cast modifier in edit-mode

Cleanup: imbuf callback naming

Fix T82520: error building freestyle with Python3.8

Caused by 16732def37c5a66f3ea28dbe247b09cc6bca6677,
This is a 'Py_ssize_t' in Python 3.8,
replace with zero as this works in both 3.7 and 3.8.

Cleanup: clang-format

Fix T81651, exact boolean modifier incorrect if operand hidden.

The code was trying to ignore hidden geometry when doing boolean,
which is correct when used as a tool, but not when a modifier.
Added a "keep_hidden" argument to bmesh_boolean to distinguish the
two cases.
Also fixed a bug when the tool is used with hidden geometry that
is attached to unhidden geometry that is deleted by the operation.
