[USETUP] Enhancements for filesystem utility functions.
- Introduce code that detects the filesystem of a (mounted?) partition, using NtQueryVolumeInformationFile() with FileFsAttributeInformation class, aka. rely on ReactOS itself (kernel, storage stack, filesystem drivers...) to recognize the FS on a partition that should normally be seen by the system. This currently half-works for whatever reason (to be insvestigated), while it works on Windows. - Fix few comments & a function parameter name. - Use NT string pointer types. svn path=/branches/setup_improvements/; revision=74529
