[NTFS]

- Add a directory entry into FCB which will be a copy of the $FILE_NAME attribute of the FILE record. Though, it won't contain the name itself (in the FCB instead), so keep first char NULL and length 0.
- Implement its support (which requires opening the FILE record 5 first) for root FCB creation.
