Added protection to the function which may have data race (according to the valgrind report). Added protection to the BRepMesh_FastDiscretFace::RestoreStructureFromTriangulation function Slight reordering to optimize use of mutex (lock once) Now Standard_Mutex::SentryNested are created as named object. Map inside TopTools_MutexForShapeProvider now store Handle_TopoDS_TShape as a key instead of TopoDS_Shape
