- Migrate all the IOCTL calls to NtDeviceIoControlFile() calls in
order to know the actual returned data and Status values.
- Add support for displaying information retrieved from:
* IOCTL_DISK_GET_DRIVE_GEOMETRY_EX ,
* IOCTL_DISK_GET_PARTITION_INFO and IOCTL_DISK_GET_PARTITION_INFO_EX
for "partition 0" (aka. the whole disk).
- Compactify the drive layouts after getting these from
IOCTL_DISK_GET_DRIVE_LAYOUT(_EX).
- Fix the HexDump() when displaying a buffer whose size is not a
multiple of 16.
