    fdisk(8): Support 4096 sector size and recognize pMBR of 4Kn disks
    
    Tweak the fdisk(8) utility to support 4096-byte sector size, so it now
    can read the pMBR on GPT-formatted 4Kn (aka 4K native) disks, e.g.,
    
         # fdisk -s vbd0
         /dev/vbd0: 14628 cyl 16 hd 56 sec
         Part        Start        Size Type Flags
            1:           1    13107199 0xee 0x00
    
    In addition, tweak read_disk() to report the read error message.
