Subject: [PATCH] Layer assignment step was ignoring the number of RoutingPad
 threshold.

* Bug: In Anabatic::layerAssign(), during the step of desaturation of
    GCells that contains too much terminals (i.e. lot of *local*
    congestion), the desaturation threshold was har-coded to 8.
    Wich is fine for symbolic cmos but way too low for Flexlib.
      End result was that most straight wires where moved towards
    the upper layers, creating congestion (imbalance of layer
    densities).
      Now the parameter:
        * "anabatic.saturateRp" (default value:8) is correctly taken
	  into account.
