Jan Höppner 5d2ebe5301 libutil: Introduce util_sys and util_sys_get_dev_addr() ...

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.
