  Modified files:
    epan                 to_str.c 
  Log:
  updates to ip_to_str[_buf]() to make them faster.
  
  This functin was in a recent profiling run the fifth most expensive function.
  It consumed ~3.5% of the total cpu in that run.
  
  Using a static table this function is now just over twice as fast as previously.
  
  My testrun calling it 10.000.000 times in a loop changed the execution time from ~17.3s ro ~8.2s
  
  If this test was representative for the speedup and if ~3.5 in the profile run
  was representative for normal cases this should make ethereal ~1.8% faster.
  Woohoo.
  (low hanging fruit)
