Tracking: Refactor, move track allocation to helper function

The caller is still responsible for allocating list of markers,
but the track allocation and initialization can now be reused.

Currently no functional changes, preparing for an upcoming
development.

Tracking: Cleanup, clarify comments in tracking settings

Make unit more explicit.

Ideally would be "embedded" into the field name itself, but this will be
more involved change.

Tracking: Cleanup, make units explicit in new track creation

Tracking: Cover markers access with basic tests

Just a beginning of tests coverage, related on the planned upcoming
development.

Fix T82918: File menu "Save Copy" shows "Save As" in File Browser

Use a dynamic name/description based on the set properties. This makes it more
clear what's going on and avoids confusion, as explained in the report.

Cleanup: Use const arguments in curve bevel

This makes it clear that only the final "r_data" is being changed.
Also rename a variable to be less vague.

Cleanup: Improve readability of curve displist building

Just a few minor improvements: declare variables where they are
initialized, decrease scope, expand some variable names, and use
LISTBASE_FOREACH.

Cleanup: Reduce indentation

Having up to nine levels of indentation make this function hard to
follow. Instead of indenting the rest of the loop for a simple special
case, just continue.

Fix unclear tooltip for the Affect Transform option of constraints.

Previous commit forgot to guard some things with #ifdef WITH_GMP.

Improve speed of Constrained Delaunay Triangulation with exact arith.

By using floating point filters, the speed improves by a factor of 2 to 10.
This will help speed up some cases of the Exact Boolean modifier.
Changed the interface of mpq2::isect_seg_seg to not return mu, as it was
not needed and not calculating it saved 15% time.

GPencil: Fix unreported assert when use select Box in single point strokes

The assert was when use segment selection mode.

Cleanup: Declare variables where initialized

Reduce variable scope, and in a few cases, use bool instead of int.

Fix wireframe opacity creating artifacts on sculpt overlay edges

When lowering the wireframe opacity with sculpt overlays enabled, the
wireframe overlay was creating white artifacts along the edges.

Cleanup: Use LISTBASE_FOREACH macro

UI: Remove excess row spacing in outliner popover

Some checkboxes had nonessential spacing between rows which made the
popover taller than needed.

Outliner: Object state filter invert toggle

This adds an invert toggle for the outliner object state filters.
There are some cases where we want a filter for invertable states (Selected,
Unselected) and having a single toggle to invert the filter reduces the
number of separate filter types needed. This removes the "Hidden" filter
which can now be replicated with an inverted "Visible" filter.

Fix (unreported) bug in liboverride diffing code for collection item insertion.

In case we do not use names, code adding new insert operations in
collections was broken.

Not a proble in practice so far, since this case was not yet in use, but
will be soon with NLA overrides.

Fix T82493: PyDoc generation throws exception on exit

Since add-ons now unregister on exit
(as of fa566157a5c351775d082b05b180c630665b4afc)
clearing functions in `bpy.app.handlers` caused an error on exit.

Resolve by restoring handlers before exiting.
