0024682: Move out B-spline cache from curves and surfaces to dedicated classes BSplCLib_Cache and BSplSLib_Cache

Browse Source 
1. B-spline cache was moved into separated classes: BSplCLib_Cache for 2D and 3D curves and BSplSLib_Cache for surfaces.

2. The cache is used now in corresponding adaptor classes (Geom2dAdaptor_Curve, GeomAdaptor_Curve and GeomAdaptor_Surface) when the curve or surface is a B-spline.

3. Algorithms were changed to use adaptors for B-spline calculations instead of curves or surfaces.

4. Precised calculation of derivatives of surface of revolution is implemented for the points of surface placed on the axis of revolution (Geom_SurfaceOfRevolution.cxx)

5. Small modifications are made to adjust algorithms to new behavior of B-spline calculation.

6. Test cases were modified according to the modern behavior.

7. Changes in BOPAlgo_WireSplitter, BOPTools_AlgoTools, BRepLib_CheckCurveOnSurface and ShapeAnalysis_Wire to use adaptors instead of geometric entities

8. Allow Geom2dAdaptor and GeomAdaptor in case of offset curve to use corresponding adaptor for basis curve

Modification of test-cases according to the new behavior.
