guido 8de2ee35f1 Fix ntfs such that it understand media with a non-512-bytes sector size: 
1. Fixups are always done on 512 byte chunks (in stead of sectors). This
is kind of stupid.
2. Conevrt between NTFS blocknumbers (the blocksize equals the media
sector size) and the bread() and getblk() blocknr (which are 512-byte
sized)

NB: this change should not affect ntfs for 512-byte sector sizes.
