interfaces: T3871: name a card by the card, not only by the slot it sits in

The map now records which card each name sat on. A card moved to another slot
keeps its name rather than leaving it behind for whatever turns up next, and
the slot it vacated does not lend that name out.

Where the map and the hardware disagree, the map wins: a card the store
already knows, found in a name's slot, takes that name. Only a card nothing
knows about, sitting in a slot on record, is treated as a replacement - the
one case which can quietly move a configured address onto another cable.
