martin c6eb40af11 Add a tool to scan disks for BSD disklabels (might be from different
archs) and add wedges for them. Similar to the kernel options
DKWEDGE_AUTODISCOVER and DKWEDGE_METHOD_BSDLABEL, and actually reusing
most of that code.

This means, for example, you can plug a sparc64 disk into an i386, run
this tool and mount the partitions (provided your kernel has the FFS_EI
option).
