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

Browse Source 
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 BRepLib_CheckCurveOnSurface to use adaptors instead of geometric entities

9. Added methods to access directly poles, knots, multiplicities of BSpline curves and surfaces
