[NTFS]

[NTFS]
- Move the ROUND_UP & ROUND_DOWN macro definition to header
- Make NtfsReadDisk() sector size aware so that it can properly align read on the disk (and thus prevent them from failing)
- If $ATTRIBUTE_LIST is non resident, then display a message and continue, don't assert on it. This is to be implemented later on.

This fixes directory enumeration on a Windows 7 NTFS volume.
