[dpdk-dev] [PATCH v4 0/6] replace attach/detach functions

The functions for EAL attach/detach had already some replacements,
so they are removed.
The functions for ethdev attach/detach are removed and replaced
thanks to a new ethdev iterator working with devargs.

    rte_eth_dev_attach(devargs, &port_id)
is replaced by:
    rte_dev_probe(devargs);
    RTE_ETH_FOREACH_MATCHING_DEV(port_id, devargs, &iterator) {
        do what you want with the new port_id
    }

The biggest benefit is to be able to manage devargs string
matching several ports to probe.
