===============================================
It is a long felt need that redundant constraints are not generated while autoconstraining.
The solver sketcher in v0.17 is überpicky with redundants due to the new popularity contest algorithm. The former behaviour is exhacerbated.
This new mode enables automatic redundant constraint removal.
In UI operations IN EDIT MODE, upon detection of redundancy by the solver, the Sketcher will remove all redundant constraints detected by that solve.
This makes the sketcher much less annoying.
How to test this?
The easiest example is to create a vertical line. Then make the endpoints symmetric with respect to the horizontal axis. Without this mode,
the vertical constraint and the symmetry constraint are redundant. With this mode, the vertical constraint gets automatically removed by the Sketcher.
=================================================
With the support for external geometry during carbon copy, it was introduced a way for creating inter-part/inter-body links. See:
https://forum.freecadweb.org/viewtopic.php?f=10&t=27700&p=223736#p223736
This commit closes this door, while still allows carbon copy with external geometry support within the same body.
======================================================
fixes#3091
Autoconstraints did not check whether the arc was CW or CCW, as such the autoconstraint on the second position was sometimes assigned to the start point.
======================================================================
Fixes#3154
About the fix:
- If a non-zero vector is passed to seekAutoConstraint, it will suggest a vertical/horizontal constraint, which does not
make sense in the construction method.
- Passing a zero vector enables to treat it like a point, so for example point on object will be suggested, but not vertical/horizontal constraints.

Carbon copy checks for parallel planes, translated origin and rotated axes, so that it can provide flipping detection when using reverse mappings.
This commit enables you to press CTRL will activating the tool in order to bypass this checks. Without the checks you will get a sketch exactly as the one
you want to copy, there are no corrections at all. This enables you to copy a profile on a new plane at a different direction for example for lofting purposes.
