    Improve gettimeofday stability
    
    These are a few tweaks to improve the stability of our gettimeofday
    startup and shutdown.  Hopefully this helps with PR10651 and PR12182,
    but that's not been confirmed yet.
    
    * runtime/runtime.h: Don't include time.c here.
    * translate.cxx (c_unparser::emit_common_header): Include time.c here,
      only if NEEDed (so we also ensure init/kill_time will be called).
      (c_unparser::emit_module_init): Change to STAP_SESSION_STOPPED for the
      final cleanup efforts, especially for time.c to wrap up.
      (c_unparser::emit_module_exit): Ditto.
    * runtime/time.c (__stp_time_timer_callback): Use the session_state
      instead of stp_timer_reregister, and continue until STOPPED.
      (__stp_init_time): Don't add_timer from the IPI.
      (_stp_init_time): Instead, add_timer_on each cpu here.
