[Libguestfs] [PATCH] inspection: Handle MD devices in fstab

[Matthew Booth]

This patch fixes inspection when fstab contains devices md devices
specified as /dev/mdN. The appliance creates these devices without reference to
the guest's mdadm.conf so, for e.g. /dev/md0 in the guest will often be created
as /dev/md127 in the appliance. With this patch, we match the uuids of detected
md devices against uuids specified in mdadm.conf, and map them appropriately
when we encounter them in fstab.

The test in this patch also checks that devices specified by their md name, e.g.
/dev/md/boot, work correctly, although the patch isn't required for devices
specified this way.
