[NTFS]

Browse source 
- Move FSCTL_GET_NTFS_VOLUME_DATA implementation in its own function GetNfsVolumeData(), so remove it from NtfsUserFsRequest()
- Add support for FSCTL_GET_NTFS_FILE_RECORD in NtfsUserFsRequest()
- Implement GetNtfsFileRecord() which returns a file record. Not fully sure about its implementation, this is to be checked.

This does not really improve the nfi situation in any kind yet...
