  Added files:

  Log:
  Add code to check the checksums of TCP segments and UDP datagrams;
  replace the existing checksummer with a modified version of the BSD
  checksumming code.  Add a flag to the "packet_info" structure to
  indicate that a packet is the first fragment of a fragmented datagram,
  so that the checksummers won't try to checksum those.
  
  (It doesn't seem to add a lot of CPU overhead, so we don't introduce a
  flag to disable it, yet.  Further checks may be necessary to see whether
  the overhead is just swamped by other overheads when scanning through a
  capture dissecting all frames, or if it truly is negligible.)
  
  Make the Boolean preference option controlling whether to make the
  top-level protocol tree item for TCP display a packet summary static to
  the TCP dissector (it doesn't need to be accessible outside the TCP
  dissector).
