[dpdk-dev] [PATCH v3 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 has been 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.

Signed-off-by: Thomas Monjalon <thomas@monjalon.net>

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