* util/hostdisk.c [__FreeBSD__]: Include sys/disk.h.
    (grub_util_biosdisk_open) [__FreeBSD__]: Add support for
    FreeBSD. Check if a device is a character device. Use
    DIOCGMEDIASIZE to get the size.
    (convert_system_partition_to_system_disk) [__FreeBSD__]: Add
    support for FreeBSD.
    (grub_util_biosdisk_get_grub_dev) [__FreeBSD__]: Check if OS_DEV
    is a character device instead of a block device. Add support for
    FreeBSD device names.

    * util/getroot.c (find_root_device) [__FreeBSD__]: Check if ENT is
    a character device instead of a block device.
    (grub_util_check_char_device): New function.

    * util/grub-probe.c (probe) [__FreeBSD__]: Check if DEVICE_NAME is
    a character device instead of a block device.

    * include/grub/util/getroot.h (grub_util_check_char_device): New
    prototype.
