Support install on multi-device filesystems.
* include/grub/emu/getroot.h (grub_guess_root_device): Renamed to ... (grub_guess_root_devices): ...this. Return char **. All users updated. * include/grub/emu/misc.h (grub_find_root_device_from_mountinfo): Removed. * util/getroot.c (find_root_device_from_libzfs): Moved pool logic to ... (find_root_devices_from_poolname): ... here. (grub_find_root_devices_from_mountinfo): Return char **. Make static. Support zfs-fuse. (grub_guess_root_device): Rename to ... (grub_guess_root_devices): ... this. Return char **. All users updated. * util/grub-install.in: Handle multi-device filesystems. * util/grub-probe.c (probe). Make device_names a char **. Add delim argument. All users updated. Handle multi-device filesystems. Use 'delim' as separator. Remove device check to allow filesystems on file. (main): Support -0 argument. Handle multi-device. * util/grub-setup.c (setup): Remove root argument. Handle multi-device. Fix a cross-device check while on it. (arguments): Remove root_dev. (argp_parser): Remove -r. (main): Remove root_dev.
