> Log:
>  The building the dev nameunit string, in devclass_add_device() is based
>  on the assumption that the unit linked with the device is invariant but
>  that can change when calling devclass_alloc_unit() (because -1 is passed
>  or, more simply, because the unit choosen is beyond the table limits).
>  This results in a completely bogus string building.
>
>  Fix this by reserving the necessary room for all the possible characters
>  printable by a positive integer (we do not allow for negative unit
>  number).
