  SVN rev 179954 on 2008-06-23 14:28:32Z by mav
  
  MFC r179480, r179924:
  Increase LINK_TABLE_OUT_SIZE from 101 to 4001 like LINK_TABLE_IN_SIZE
  to reduce performance degradation under heavy outgoing scan/flood.
  Scalability is now much more important then several kilobytes of RAM.
  
  Remove unneded TCP-specific expiration handeling. Before this connected
  TCP sessions could never expire. Now connected TCP sessions will expire
  after 24hours of inactivity.
  
  Simplify HouseKeeping() to avoid several mul/div-s per packet. Taking into
  account increased LINK_TABLE_OUT_SIZE, precision is still much more then
  required.
