New Revision: 220740

Log:
  ktrace: Log the code for all signals (PSIG events).
  
  The code provides information on how the signal was generated.
  
  Formerly, the code was only logged for traps, much like only signal handlers
  for traps received a meaningful si_code before FreeBSD 7.0.
  
  In rare cases, no information is available and 0 is still logged.
