Many tools need to identify the device address of a given device. So far, either the tool had its own implementation, or u2s_getbusid() was used. Though, u2s_getbusid() was mainly designed for and used by the DASD tools. Introduce util_sys with a first function util_sys_get_dev_addr() which provides a more universal way to identify the device address which is not limited to one particular device type. The device address represents either a busid (e.g. DASD), slot address (NVMe), H:C:T:L tuple (SCSI), or other id types associated with a device. Signed-off-by: Jan Höppner <hoeppner@linux.ibm.com>
