scsi_id: Export WWN and Unit Serial Number
Since the Unit Serial Number and the WWN are useful bits of
information export them as properties in the udev database. These
bits of information are often printed on the physical disk, see
and displaying them separately in the UI (or in /dev/disk) might help
users identify the physical disk. This patch exports these bits of
information as ID_WWN and ID_SCSI_SERIAL.
Unfortunately we can't overload ID_SERIAL for two reasons
1. ID_SERIAL (and ID_SERIAL_SHORT) exported by scsi_id isn't really
the unit serial number (as defined by SCSI) - it is sometimes the
WWN (since it is more unique than the Unit Serial Number) and
complex rules (to make the serial unique) govern what value to
use.
2. It would break existing setups if the value of ID_SERIAL changed
