only lvs or only pvs are used whereas it seems that they are used
interchangeably.
* grub-core/disk/lvm.c (read_node): New function.
(read_lv): Use read_node.
(grub_lvm_scan_device): Use only first mirror on pvmove'd lvs.
Match volumes only at the end when all lvs are found. Take both
pvs (first) and lvs (second) into account.
* include/grub/lvm.h (grub_lvm_segment): Merge fields stripe_* and
mirror_* into node_*. All users updated.
(grub_lvm_stripe): Merge this ...

rather than the file it points to. This fixes use of freed memory
if an existing loopback device is replaced.
* grub-core/disk/loopback.c (grub_loopback_open): Store dev in
disk->data, not dev->file.
(grub_loopback_read): Adjust file assignment to match.
Fixes Ubuntu bug #742967.

division and module with bit operations.
(grub_jfs_find_file): Make ino a grub_uint32_t.
(grub_jfs_lookup_symlink): Likewise. Use 64-bit quantities
warning. (This was in fact always initialised before use, but GCC
wasn't smart enough to prove that.)
