0021077: EDF 1695 SMESH: Netgen works bad with 1D hypothesis on an elliptic torus
   1) catch signals within netgen, report the meshing step where a signal occures
   2) make simple hypothesis work via local size restriction to avoid
      restricting size by netgen due to edge curvature

This fix includes the fix for issue 0021073: Local size on edge creates unreguler 1D elements
