[dpdk-dev] [PATCH v4 1/4] devargs: remove deprecated functions

[Thomas Monjalon <thomas@monjalon.net>]

rte_eal_parse_devargs_str() does not support parsing the bus name
at the start of devargs. So it was renamed and deprecated.

rte_eal_devargs_add(), rte_eal_devargs_type_count() and
rte_eal_devargs_dump() were declared deprecated and had their
implementation body renamed.

All these functions were deprecated in release 18.05.

The library version is not updated because it should be done
in earlier patch https://patches.dpdk.org/patch/43903/
