[USETUP] Improve the NTOS installations detector.
In all the disks/partitions available, it searches for the presence of freeldr.ini / boot.ini, open & parse them, and enumerates the available boot entries (as candidates for installations). For each of them, it maps their ARC paths into the NT namespace (hence the ARC 2 NT path resolver committed in r74621), then attempts to detect in these paths the existence of NTOS installations. svn path=/branches/setup_improvements/; revision=74622
