* The debug_thread_info records now, which signals the debugger wishes

not to be notified.
* Added debugger commands for setting/getting of thread signal ignore
  masks and signal handlers.
* Renamed user_debug_fault_occurred() to a more correct
  user_debug_exception_occurred(). It no longer sends a `stopped' message,
  but the new one dedicated to exceptions. Additionally the number of the
  signal is supplied that will be sent, when the thread continues (without
  indicating to ignore the event).
