Rename Solaris disks as cXtXdX instead of sdX or ssdX

Hello,

This patch defines a new config key "UseSolariscXtXdXName" to use the Solaris notation of disks cXtXdX instead of sdX or ssdX.

It uses /etc/path_to_inst and the links in /dev/dsk to find the cXtXdX name from the kstat name.

Regards,
Yves
