Subject: [PATCH] Split 59-scsi-sg_utils.rules for multipath support

The current rules file combines the setting of environment
variables and the generation of persistent symlinks.
The causes issues with multipathing, as multipath needs to have
access to the WWID to be able to decide if the device should be
handled by multipath (and hence no symlinks should be created)
or not (and udev can proceed with creating symlinks).
So this patch splits off the rules file in two sections,
55-scsi-sg3_id.rules and 58-scsi-sg3_symlink.rules.
This allows multipath rules to be inserted between them
to make the correct decision.
