0029115: [Regression] GeomAdaptor mistakenly reports non-periodic curves to be periodic

1. Section "Concept of periodicity applied in OCCT-algorithms" has been added in Doxigen-documentation

2. Method IsPeriodic() of classes Geom(2d)_TrimmedCurve has changed its behavior. Please see the documentation about correspond methods.

3. Methods IsUPeriodic() and IsVPeriodic()  has changed their behavior.

4. Methods Geom_SurfaceOfLinearExtrusion::UPeriod() and Geom_SurfaceOfRevolution::VPeriod() has changed their behavior.

5. Method GeomLib::IsClosed(...) has been added in order to check closure of 3D/2D curve with some tolerance.

6. Methods ShapeAnalysis_Curve::IsPeriodic(...), BRepBlend_HCurve2dTool::IsPeriodic(...), Contap_HCurve2dTool::IsPeriodic(...), IntPatch_HCurve2dTool::IsPeriodic(...), BRepBlend_HCurveTool::IsPeriodic(...) have been removed.

7. Method

   void BOPTools_AlgoTools2D::AdjustPCurveOnFace (const TopoDS_Face& theF,
                                                  const Handle(Geom_Curve)& theC3D,
                                                  const Handle(Geom2d_Curve)& theC2D,
                                                  Handle(Geom2d_Curve)& theC2DA,
                                                  const Handle(IntTools_Context)& theContext = Handle(IntTools_Context)());

has been removed.

8. The following classes have become abstract (some methods have become pure virtual): Adaptor2d_Curve2d, Adaptor3d_Curve, Adaptor3d_Surface.

9. Methods ChFiDS_ElSpine::IsClosed() GeomFill_SnglrFunc::IsClosed(), ProjLib_CompProjectedCurve::IsClosed(), ProjLib_CompProjectedCurve::IsPeriodic(), ProjLib_CompProjectedCurve::Period() have been created.

10. Methods GeomLib::AllowExtend(...), GeomLib::AllowExtendUParameter(...) and GeomLib::AllowExtendVParameter(...) have been created.

11. Interface of Geom_ConicalSurface::Apex(...) method has been corrected insignificantly.

12. Method IntTools_Tools::IsClosed(...) has been removed.
