  Log:
  Introduce the new function
          p_trespass(struct proc *p1, struct proc *p2)
  which returns zero or an errno depending on the legality of p1 trespassing
  on p2.
  
  Replace kern_sig.c:CANSIGNAL() with call to p_trespass() and one
  extra signal related check.
  
  Replace procfs.h:CHECKIO() macros with calls to p_trespass().
  
  Only show command lines to process which can trespass on the target
  process.
