MFC kern_sig.c 1.319 sys_process.c 1.134 to RELENG_5:

  Avoid kernel panic when attaching a process which may not be stopped
  by debugger, e.g process is dumping core. Only access p_xthread if
  P_STOPPED_TRACE is set, this means thread is ready to exchange signal
  with debugger, print a warning if P_STOPPED_TRACE is not set due to
  some bugs in other code, if there is.

  The patch has been tested by Anish Mistry mistry.7 at osu dot edu, and
  is slightly adjusted.
