kgv c22b52d60e 0028966: Coding Rules - remove Adaptor2d_HCurve2d, Adaptor3d_HCurve and Adaptor3d_HSurface classes 
Adaptor2d_Curve2d, Adaptor3d_Curve and Adaptor3d_Surface now inherit Standard_Transient.
Interfaces Adaptor2d_HCurve2d, Adaptor3d_HCurve, Adaptor3d_HSurface and their subclasses
are now aliases to Adaptor2d_Curve2d, Adaptor3d_Curve and Adaptor3d_Surface.
Removed numerous unsafe reinterpret casts.

Generic classes Adaptor3d_GenHCurve, Adaptor3d_GenHSurface, Adaptor2d_GenHCurve2d have been removed.
Several redundant .lxx files have been merged into .hxx.

Removed obsolete adaptor classes with H suffix.
