    kernel - Enhance the FAIRQ ALTQ to use relative weightings
    
    * Previously the FAIRQ altq specification guaranteed a bandwidth minimum
      for each queue but then used a fixed priority model for any excess
      bandwidth.
    
    * Now the FAIRQ uses the minimum bandwidth specifications to also calculate
      relative weightings for any excess bandwidth, and no longer uses a fixed
      priority model.
    
    * This results in a better apportionment of excess bandwidth and allows
      bandwidth specifications to also be used as a pure weighting specification
      if desired.
    
    * Fix bandwidth calculation.  The decay was being executed on every packet
      instead of once a second.
