These features, based on the code for the Pipe class, allow the user
to simply create a helical sweep within PartDesign workbench.
Sample application is threads, springs, coils, augers, etc.
Also, remove needless requirement for positive cone angle on helixes.
Thanks to @bitacovir for helping with the icons
Thanks to @chennes for review
Thanks to @vosk for review
Thanks to @wwmayer for review
Enforce that links stay within scope for ProfileBased features
This also ensures that the Body itself is not used for creating features within
the body, causing a "Graph not a DAG" error.

- Long overdue refactor to avoid repetition during save/restore and copy.
- New interface to notify an extension when it is attached. It also enables the extension to gain
a pointer to the geometry container. This is intended to extend the functionality already existing
in Part::Geometry.
===============================================
Before this implementation, specific status via former mergeOverlayIcon() was greyed out
with the visibility.
With this commit, the developer has two options:
a) override mergeGreyableOverlayIcons, in which case the overlay will
be greyed out when the item is greyed out as per former mergeOverlayIcon()
b) override mergeColorfulOverlayIcons, in which case the overlay will
be superimposed after the icon is greyed out as it is the case for stardard
error and recompute flags.
the arrow heads are much too large so that the feature use quite useless
The PR fixes this to make the arrow heads as large as for linear dimensions
It also slightly increase the arrow head size since.
Add the optional Qt::MSWindowsFixedSizeDialogHint parameter to all uses of the QInputDialog::getX static functions to silence a Qt/Windows debug mode warning about QWindowsWindow::setGeometry: Unable to set geometry. Increase the size of the unit calculator to eliminate the same warning. Finally, call adjustSize() on the "Unsaved Changes" dialog to silence the warning.
=================================================================================
Some geometry extensions do not provide a PyObject as they do not have a Python counterpart
as it would serve no purpose to have it.
This commit handles this situation making sure to provide the right error to Python
or to ignore the extension where appropriate.
==================================================================
GeometryExtension was originally designed to be serializable (save/restore). However,
GeometryMigrationExtension and ViewProviderSketchGeometryExtension have demonstrated the
usefulness of runtime-only GeometryExtensions.
The problem with runtime-only extensions being of a serializable type (GeometryExtension before
this commit) arises when Part::Geometry is to serialize the extensions and serialise the number
of extensions the geometry has. If runtime-only GeometryExtensions do not save a tag, then the
restore mechanism will expect more extensions that are actually in the XML file.
This commit makes GeometryExtension by default not serializable and deriving directly from
Base::BaseClass. A new class GeometryPersistentExtension is created, deriving from GeometryExtension
to provide serialisation. All Extensions requiring serialization derive from GeometryPersistentExtension
and those not requiring it from GeometryExtension directly.
This commit adapts all extensions to the new situation:
Part: GeometryDefaultExtension
Part: GeometryMigrationExtension
Sketcher: ViewProvierSketchGeometryExtension
Sketcher: SketchGeometryExtension and ExternalGeometryExtension
