  qapi: Convert block_set_io_throttle
  qapi: Convert change
  qerror: Extend QERR_DEVICE_ENCRYPTED
  qapi: Introduce change-vnc-password
  monitor: expose readline state
  qapi: Convert eject
  block: eject_device(): Use error_set()
  qapi: Convert expire_password
  qapi: Convert set_password
  vnc: Simplify vnc_display_password()
