0025880: fuzzy booleans with multiple tools

New features:
class BOPTools_AlgoTools2D
method:
 Standard_Integer BOPTools_AlgoTools2D::AttachExistingPCurve
   (const TopoDS_Edge& aEold,
    const TopoDS_Edge& aEnew,
    const TopoDS_Face& aF,
    const Handle(IntTools_Context)& aCtx)
has been added.

Purpose:
  To attach P-Curve on surface of the face <aF>  from the edge <aEold>
   to the edge <aEnew>
   It returns 0 in case of success.

Changes:
1. class BOPTools_AlgoTools
method:
 Standard_Boolean BOPTools_AlgoTools::IsSplitToReverse
  (const TopoDS_Face& theFSp,
   const TopoDS_Face& theFSr,
   Handle(IntTools_Context)& theContext)

The condition for a point on the surface of a face has been changed.

2. class BOPAlgo_PaveFiller
method:
 void BOPAlgo_PaveFiller::MakePCurves()

The treatment of E/E common bocks has been changed
to use mechanism of attacment P-Curves [ I.1 ]

Test case for issue CR25880
