    runtime: switch to deferred STP_EXIT signalling
    
    The former code allowed stapio to have two concurrent commands sent
    toward the runtime at the same time: one from the main loop and
    another one from the signal handling thread.  This is suspected to
    have caused occasional lockups.  This new code switches to a deferred
    signal handling model, where the signal handling thread merely
    increments a counter, and the main loop monitors that count.
    Unfortunately, this currently involves switching the main loop's
    blocking /.ctl read into a nonblocking poll.
    
    * runtime/staprun/mainloop.c (pending_interrupts): New variable.
      (signal_thread): Increment it.
      (stp_main_loop): Check it.
