0026894: Intersection algorithm between two infinite cylinders is hanging

1. VRange of intersection curve has been limited. As result, too oblong intersection curve(s) will be never returned.
2. Now, purger algorithm is not called for lines obtained by Geom-Geom intersection method.
3. New statuses are entered in IntPatch_ImpImpIntersection class. It makes intersection algorithm more informative and flexible for using.
4. Method IntPatch_ImpImpIntersection::GetStatus() has been created.
