Increase LVM implementation robustness in order not to crash on
configurations like pvmove. Previously code assumed that in some places
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.

mirror_* into node_*. All users updated.
(grub_lvm_stripe): Merge this ...
(grub_lvm_mirror): ... and this ...

Store the loopback device as data on loopback grub_disk structures,
