Make kFreeBSD code more generic to support ext2fs as root, ufs as
a separate module and maybe other interesting combinations.
* util/grub.d/10_kfreebsd.in (load_kfreebsd_module): New function.
(kfreebsd_entry): Use load_kfreebsd_module() to load modules.
(kfreebsd_entry): Add generic filesystem module load routine.
Map GRUB `ext2' to kFreeBSD `ext2fs'.
* util/grub.d/10_kfreebsd.in: Initialize ${kfreebsd_device} as the
kFreeBSD device name, except on ZFS where the filesystem label is
used.
(kfreebsd_entry): On ZFS root, load `opensolaris.ko', `zfs.ko' and
`/boot/zfs/zpool.cache'.
Set mountfrom kernel variable using ${kfreebsd_device}.
Make it even harder to use uninitialized `libzfs_handle' (and
make the interface a bit simpler).
* include/grub/util/misc.h (grub_util_init_libzfs)
(libzfs_handle): Remove.
(grub_get_libzfs_handle): New prototype.
* util/misc.c [HAVE_LIBZFS] (libzfs_handle): Add `static'
attribute.
(grub_util_init_libzfs): Remove.
(grub_get_libzfs_handle): New function.
* kern/emu/getroot.c (find_root_device_from_libzfs): Use
grub_get_libzfs_handle() to obtain a libzfs handle instead of
accessing `libzfs_handle' directly.
Prevent accidental use of uninitialized libzfs_handle.
* util/grub-probe.c (main): Move grub_util_init_libzfs() call to ...
* kern/emu/getroot.c (find_root_device_from_libzfs): ... here.
* util/misc.c (grub_util_init_libzfs): Make this function idempotent.
Enable `grub-probe -t device' resolution on ZFS.
* configure.ac: Check for getfsstat(), libzfs and libnvpair.
* include/grub/util/libnvpair.h: New file.
* include/grub/util/libzfs.h: New file.
* kern/emu/getroot.c: Include `<assert.h>' and `<error.h>'.
[HAVE_LIBZFS && HAVE_LIBNVPAIR]: Include `<grub/util/libzfs.h>' and
`<grub/util/libnvpair.h>'.
[HAVE_GETFSSTAT]: Include `<sys/mount.h>'.
(find_mount_point_from_dir): New static function.
[HAVE_LIBZFS && HAVE_LIBNVPAIR] (find_root_device_from_libzfs): New
function.
[HAVE_LIBZFS && HAVE_LIBNVPAIR] (grub_guess_root_device): Use
find_root_device_from_libzfs() before ressorting to find_root_device().
* include/grub/util/misc.h (grub_util_init_libzfs): New function
prototype.
* util/misc.c: Include `<grub/util/libzfs.h>'.
(grub_util_init_libzfs): New function.
[HAVE_LIBZFS] (libzfs_handle): New global variable.
[HAVE_LIBZFS] (fini_libzfs): New static function.
(grub_util_init_libzfs): New function.
* util/grub-probe.c (main): Call grub_util_init_libzfs().

Generate device.map in something closer to the old ordering.
* util/deviceiter.c (struct device): New declaration.
(compare_file_names): Rename to ...
(compare_devices): ... this. Sort by kernel name in preference to
the stable by-id name, but keep the latter as a fallback comparison.
Update header comment.
(grub_util_iterate_devices) [__linux__]: Construct and sort an array
of `struct device' rather than of plain file names.
