Fix T90791: Knife project leaks memory with curve/text cutter

Cleanup: rename BKE_mesh_free -> BKE_mesh_free_data

It wasn't obvious this didn't free the memory of the mesh it's self
leading to memory leaks.

Cleanup: accidentally included printf

[2.93 only] pose slide factor wrong in redo popup

Originally this was caused by {rBc71a8e837616}.
Above commit wasnt renaming RNA definitions, but not the occurances were
RNA values were set.

In 3.0, we had improvements to pose-sliding tools (D9054) where this was
somewhat ironed out (only partially, see D12187).

But since the pose-sliding improvements are not part of 2.93, we have to
correct this in 2.93 ONLY.

Fix T83164: Spline IK `joint_bindings` parameter is broken.

Code freeing the array would not properly reset its length value to
zero.

Note that this corrupted data could also be saved in .blend files, so
had to bump fileversion and add some doversion code too.

Fix T90166: crash when creating a liboverride.

Cleanup/Fix RNA array length accessors returning non-zero values in invalid cases.

This was apparently done in two places only, with a very cryptic comment
(`/* for raw_access, untested */`), and... I cannot see how returning a
non-zero length value for an array that does not exist or is not
accessible at least, would be anything but an obvious source of issues.

Note that both commits adding those lines are from stone ages (2009):
rBcbc2c1886dee and rB50e3bb7f5f34.

Fix T89835: Crash after Instancing to Scene after making linked Collection local.

Even though the ID itself remain the same after being made local, from
depsgraph point of view this is a different ID. Hence we need to tag all
of its users for COW update, as well as rebuild depsgraph relationships.

Should be also backported to LTS 2.93 (and 2.83 if possible).

Fix T87041: Driver Editor not updated in realtime

Caused by {rBbbb2e0614fc3}

Since above commit only the playhead is updated as an overlay in
animation playback (was moved out of drawing of the main region for
perfomance reasons).
The driver value "debug" visualization is very useful to have during
playback though but was left in main region drawing as part of
`draw_fcurve` (thus does not update in realtime anymore).

Moving `graph_draw_driver_debug` into the overlay is not feasible
because it requires animation filtering which has significant overhead
which needs to be avoided in the overlay which is redrawn on every UI
interaction.

Now tag the whole main region for updates in the Driver Editor during
playback instead (which will make the Drivers Editor as slow during
playback as before rBbbb2e0614fc3 -- but with realtime updates of the
debug visualization).

Fix T78469: Output Metadata: Strip Name no longer accessible

Caused by rB7fc60bff14a6.

This has actually been reported and closed, but that was clearly a
misunderstanding (above commit changed a checkbox to be an enum, but a
second checkbox was simply removed)

Fix T88807: crash when there are multiple links between the same sockets

This commit does two things:

* Disallows creating more than one link from one socket to a multi socket input.
* Properly count links if there happen to be more than one link between the same sockets.

The new link counting should also be more efficient asymptotically.

Fix particle system duplication duplicates all systems

Followup to rB3834dc2f7b38 (where getting the proper particle system was
fixed for the Adjust Last Operation panel in the Properties Editor). But
since this operator can also be called from the 3DView, get a current
particle system there as well.

Without this, _all_ particle systems would be copied when executing from
the 3DView (which was never really intended [operator description uses
singular] -- it just happens to use `copy_particle_systems_to_object`
internally as well -- same as the `Copy Active/All to Selected Objects`
operators)).

Speedup rigid body "Copy from Active" operator

If there were lots of selected objects without an existing rigid body,
we would add rigid bodies to them one by one.

This would be slow in python, now we instead do this as a batch
operation in C.

On my (Intel) MacBook it used to take 60 seconds and with this change it
takes about 0.3 seconds.
