Log:
[USETUP]: On-going improvements 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.
