Extrema_GenExtPS now prefers resizing of Array2 tables instead of managing tables by extra handles. Removed unsafe casts to Adaptor3d_SurfacePtr/Adaptor3d_CurvePtr in Extrema classes. Removed unsafe casts to curve adaptors in Extrema_ExtCC, Extrema_ExtCC2d classes. Extrema_GenExtPS, Extrema_GenExtSS, Extrema_ExtCS - copies by value are now disallowed; several unexpected places copying the object have been fixed. IntTools_Context - maps of void* have been replaced by typed maps.
