At present sandbox uses the root device as the parent for block devices it creates to provide access to files on the host. This is convenient but is not really correct, since the root device should not have any particular meaning for its children.
This series tidies this up, introducing a new uclass and updating the implementation accordingly. Rather than numbering host devices, it is now possible to provide a label, which is easier to deal with.
The host command has some minor updates, including showing the label. A test and documentation are added for it also.
A few other minor improvements are included also.
