0027131: [Regression to 6.7] DistShapeShape performance loss
Lipchitz constant approximation and fixes in global optimization algorithm added to improve performance.
Test case added.
Fix backporting:
0026593: Coding rules - revert compatibility of NCollection_CellFilter constructor with old code
Restored old constructor and old behavior where possible.
Minor correction.
0026395: Merge clasees NCollection_CellFilter_NDim and NCollection_CellFilter
