Correct the algorithm to get right Start point for extension of the walking line.
Test case for issue CR26197
Correction of test case bugs/modalg_6/bug26197
1. Function IntImp_Int2S::ChangePoint() has been added (see cdl for detail information).
2. Attempt to forbidden break WLine if it goes along surface boundary.
Code optimization.
2nd optimization
Test case for issue CR25890
Macros ending on "DEB" are replaced by OCCT_DEBUG across OCCT code; new macros described in documentation.
Macros starting with DEB are changed to start with "OCCT_DEBUG_".
Some code cleaned.
Changed next point computation in IntWalk_PWalker.cxx.
Now trying to walk over another isoline if new point is too close to previous.
Test case for issue CR25380
1) Generic class "Intf_InterferencePolyhedron" from "Intf" package converted to the non-generic class and moved to the "IntPatch" package. Name of this class was changed to "IntPatch_InterferencePolyhedron".
2) Generic class "MoniTool_Elem" from "MoniTool" package converted to the non-generic class "MoniTool_TransientElem".
3) Generic class "IntWalk_PWalking" from "IntWalk" package converted to the non-generic class. And internal class "TheInt2S" of "IntWalk_PWalking" moved from IntWalk_PWalking.cdl to IntWalk.cdl for correct building. Also several "*.cxx" files of this class merged to one ".cxx".
4) Generic class "Transfer_SimpleBinder" from "Transfer" package converted to the non-generic class and moved to the "TransferBRep" package. Name of this class was changed to "TransferBRep_BinderOfShape".
5) Generic class "Geom2dInt_CurveTool" from "Geom2dInt" package converted to the non-generic class "Geom2dInt_Geom2dCurveTool".
6) Generic class "MAT2d_BisectingLocus" from "MAT2d" package converted to the non-generic class and moved to the "BRepMAT2d" package. Name of this class was changed to "BRepMAT2d_BisectingLocus".
7) Generic class "MAT_Mat" from "MAT" package converted to the non-generic class and moved to the "MAT2d" package. Name of this class was changed to "MAT2d_Mat2d".
