[NTFS] - Add the most basic support for file creation. Expand diagnostic output, especially in NtfsDumpIndexRootAttribute(). Replace an ExFreePool() with ExFreePoolWithTag().

AddFileName() - Add a parameter to receive the Mft index of the parent directory. Fix so the name of the file will be stored in the attribute, not the name of the directory.
NtfsCreateFile() - Open a file that was successfully created, instead of assuming failure.
NtfsCreateFileRecord() - Add the filename attribute of the created file to the parent directory's index.
+NtfsAddFilenameToDirectory() - Adds a $FILE_NAME attribute to a given directory index. Presently, a file can be created in an empty directory only.
AddNewMftEntry() - Add a parameter to receive the mft index where the new entry was stored.
