* ignore -Wfree-nonheap-object for generated code
* replace 0 with Qt::NoModifier when creating a QKeyEvent
* in Qt 5.14 QCombobox::activated(QString) is deprecated, use textActivated
* don't mix QCheckBox::setChecked() with tristate API
Comments by @abdullahtahiriyo.
Remove default values and smaller constructor for `CenterOfGravity` and
`WeightedLinearCombination` constraints.
Clarify comments.
Improve readability of `CenterOfGravity` and `WeightedLinearCombination`
constraints.
Also squashes:
[Sketcher] Create center of gravity constraint in planegcs
[Sketcher] typo
[Sketcher] Use accurate "weights" for knots
By weights we mean the linear combination factor B_i(x) such that
spline(x) = sum(pole_i * B_i(x)) for _non-rational_ splines.
[Sketcher] Use more appropriate weights for knots
These are relevant for knots _away_ from any ends (and possibly other high
multiplicity knots).
[Sketcher] Make COG constraint weights user-definable
[Sketcher] Make `flattenedknots` for periodic B-Splines
[Sketcher] Fix incorrect setup of `flattenedknots`
Without ensuring enough space, iterators become invalid. These iterators are
needed because for periodic B-splines we need to pad flattenedknots with offset
values within flattenedknots.
Apparently there is still some iterator issues even after the reserve. Just use
fresh vectors instead.
[Sketcher] Apply knot constraints by parameter
Hopefully this will allow directly applying constraints on knots.
[Sketcher] Disable some knot updating
[Sketcher] Use center of gravity constraint on knots
[Sketcher] Fix knot COG constraint for periodic splines
[Sketcher] Add start/end point of periodic spline to solver
This removes the trouble of transferring constraints to the underlying knot.
[Sketcher] Support knot constraints on rational B-splines
[Sketcher] Remove virtual from overridden methods in planegcs
Follow 0penbrain's comments
[Sketcher][planegcs] Use `unsigned int` in signatures
Also `size_t` at places

In particular this hides edit-mode sketcher toolbars when in non-edit-mode.
And hides non-edit-mode toolbar when in edit-mode.
It also hides the structure toolbar when in edit-mode (as it is completely deactivated)
* QApplication::setFallbackSessionManagementEnabled has been removed
* QString::medRef() has been removed. Use QString::mid() again.
* QTextStream::setCodec has been removed
* Use operator QVariant of the QFont class to make code Qt5 and Qt6 compatible
* Signature of QTreeWidget::mimeData() has changed in Qt6. Remove TreeWidget::mimeData() because it doesn't change the implementation
* QLayout::setMargin() is deprecated in Qt5 and has been removed in Qt6. Use QLayout::setContentsMargins()
* QDateTime::toTime_t() is deprecated in Qt5 and has been removed in Qt6. Use QDateTime::toSecsSinceEpoch()
* QDesktopWidget is deprecated in Qt5 and has been removed in Qt6. Use QScreen
Removes the BUILD_QT5 flag and adds a new FREECAD_QT_VERSION option,
which can be set to either "Auto" (default), 5, or 6. Auto detects which
version of Qt is installed on the system and chooses it. If both version
are installed, Qt5 is used.
Note that this DOES NOT implement compiling against Qt6, it only adds
the necessary cMake infrastructure to begin work on the source code
changes that will be required.
