Illumos support.

* Makefile.util.def (10_illumos): New script.
	* configure.ac: Set COND_HOST_ILLUMOS.
	* grub-core/kern/emu/hostdisk.c (grub_util_get_fd_sectors) [__sun__]:
	Support Illumos calls.
	(find_partition_start) [__sun__]: Likewise.
	(convert_system_partition_to_system_disk) [__sun__]: Likewise.
	(device_is_wholedisk) [__sun__]: Handle Illumos naming scheme.
	(grub_util_biosdisk_get_grub_dev) [__sun__]: Handle Illumos.
	* util/getroot.c (find_root_device_from_libzfs) [__sun__]: Return raw
	device.
	* util/grub-probe.c (probe) [__sun__]: Do character check.
	* util/grub.d/10_illumos.in: New file.
