0027998: Self-intersection is not detected

Browse Source 
New method CheckFaceSelfIntersection has been added to BOPAlgo_CheckerSI: now self-intersection of each face is found as well as pairs of intersecting faces;

-method IntPatch_Intersection::Perform(S1,D1,TolArc,TolTang) is modified for more effective search of self-interasections in case of Surface Of Extrusion;

-method IntCurve_IntPolyPolyGen::Perform(C1,D1,TolConf,Tol,NbIter) is modified to detect segments of intersections.

Small correction.

Test cases are corrected.

Correction of compiler error

Fix of regressions
