DwM: Show wire only mesh objects

Fix manipulator immediate mode use

Needs 3D coords

Fix various issues in RNA diff handling, and make some more props overridable.

Namely, those allowing to link an object to an armature.

Thing is, we cannnot and absolutely do not want to use same trick as
armature proxies regarding deforming their related geometries.

So instead, we'll automatically make override of objects using
overridden armature as deformer, ultimately. This also allows for
several overrides of a same linked data.

Not sure how much good/bad this is, will have to ask artists once it's
ready for testing (cannot think of any non-ugly way to do that 'magic
trick' tbh).

Only apply clamping to the actual auto clamp keyframes.

Clamping adjacent handles doesn't seem to be that good after all.

Implement smoothed auto handle placement with cyclic extrapolation.

Cyclic extrapolation is implemented as an f-curve modifier, so this
technically violates abstraction separation and is something of a hack.
However without such behavior achieving smooth looping with cyclic
extrapolation is extremely cumbersome.

The new behavior is applied when the first modifier is Cyclic
extrapolation in Repeat or Repeat with Offset mode without
using influence, repeat count or range restrictions.

Implement a new automatic handle algorithm to produce smooth F-Curves.

The legacy algorithm only considers two adjacent points when computing
the bezier handles, which cannot produce satisfactory results. Animators
are often forced to manually adjust all curves.

The new approach instead solves a system of equations to trace a cubic spline
with continuous second derivative through the whole segment of auto points,
delimited at ends by keyframes with handles set by other requirements.

This algorithm also adjusts Vector handles that face ordinary bezier keyframes
to achieve zero acceleration at the Vector keyframe, instead of simply pointing
it at the adjacent point.

Original idea and implementation by Benoit Bolsee <benoit.bolsee@online.be>;
code mostly rewritten to improve code clarity and extensibility.

Trigger FCurve handle recalculation on updates to curve modifiers.

If automatic curve handles are changed to be aware of the Cycles
modifier to provide a smooth loop transition, they have to be updated
when the modifier is added, removed or its options change.

Due to the way code is structured, it seems it requires a helper
link to the containing curve from the modifier object.

Add an FCurve flag to toggle new smoothing behavior.

Merge remote-tracking branch 'origin/master' into experimental-build

Task scheduler: Optimize subsequent pushing bunch of tasks

The idea is to accumulate all new tasks in a thread local queue
first without doing any thread synchronization (aka, locks and
conditional variables) and move those tasks to a scheduler queue
once they are all ready. This way we avoid per-task-pool lock
and only have one lock per bunch of tasks.

This is particularly handy when scheduling new dependency graph
node children. Brings FPS of cached simulation from the linked
below file from ~30 to ~50.

See documentation for BLI_task_pool_delayed_push_{begin, end}
and for TaskThreadLocalStorage::do_delayed_push.

Fixes T50027: Rigidbody playback and simulation performance regression with new depsgraph

Thanks Bastien for the review!

Merge branch '28' into custom-manipulators

Fix bone selection (index can't skip hidden bones)

Cleanup: Easier to read constant name

Fix T51661: Swaping strips does not refresh sequencer

Cleanup: Use more clear parenthesis

Fix outliner crash clicking on pose bones

From 15317775c, we can't assume directdata is a Base.
This matches logic from master.

Cleanup: Deduplicate macro code, comments, redundant struct definitions

fix for convert to keyframes, needs no bake and should be initialized properly after refracture

Some cleanup, introduce idea of 'override template'.

Nothing functionnal for now, just made it possible for override to have
NULL reference ID.

Those overrides would be used as templates (created in original file of
the ID, they define some kind of default overriding settings). They
should also allow to forcefully lock some properties (forbid users of
that library ID to override some properties).
