Affected Issues  0033187: Modeling Algorithms - Crash in postprocessing of imported shape
Changeset 0033187: Modeling Algorithms - Crash in postprocessing of imported shape

Problem: Desynchronization of behaviors of GeomAdaptor_Curve::NbIntervals and
 GeomAdaptor_Curve::Intervals functions. First calculates number of intervals, then
 array is created and second fills the array. In some cases the size of array
 is less than need for filling.

Change:
1. Added function BSplCLib::Intervals that calculates number of interval and fills
 the array with its (if needed).
2. Simplified the algorithm of intervals calculation.
3. GeomAdaptor_Curve::NbIntervals/Intervals and Geom2dAdaptor_Curve::NbIntervals/Intervals
 use BSplCLib::Intervals.
4. When creating an adapter for the base curve, the boundaries of the adapter for the offset curve are applied.
5. Test for problem shape was created: bugs modalg_8 bug33187.

Result: The new approach eliminates the problem of writing outside the array bounds.
