    all: add "${MAC}" substituion for "connection.stable-id" · 7ffbf712

    We already had "${DEVICE}" which uses the interface name.
    In times of predictable interface naming, that works well.
    It allows the user to generate IDs per device which don't
    change when the hardware is replaced.
    
    "${MAC}" is similar, except that is uses the permanent MAC
    address of the device. The substitution results in the empty
    word, if the device has no permanent MAC address (like software
    devices).
    
    The per-device substitutions "${DEVICE}" and "${MAC}" are especially
    interesting with "connection.multi-connect=multiple".
