[patch] grub-install for FreeBSD

[HASEGAWA Tomoki]

I hack grub-install utility for FreeBSD(-4.2).  I test only
installation to /dev/ad0 on my FreeBSD-4.2-STABLE machine, but even da
or so will work.

ChangeLog:
* lib/device.c [__FreeBSD__] (get_ide_disk_name): Add support for FreeBSD-4.0 
or later. Use "/dev/rad0".
* util/grub-install.in (convert): Add the code for FreeBSD disklabels.
