In current design, legacy parser rte_devargs_parse() saved scratch
buffer to devargs.args while new parser rte_devargs_layers_parse() saved
to devargs.data. Code using devargs had to know the difference and
cleaned up memory accordingly - error prone.
This patch unifies scratch buffer to data field, introduces
rte_devargs_reset() function to wrap the memory clean up logic.

There is a common macro __rte_unused, avoiding warnings,
which is now used where appropriate for consistency.

The sample code demonstrates device (ethdev only) management
at a multi-process environment. The user can attach/detach a
device on primary process and see it is synced on secondary
process automatically.
How to start?
./hotplug_mp --proc-type=auto
Command Line Example:
>help
>list
/* attach a pci device */
> attach 0000:81:00.0
/* detach the pci device */
> detach 0000:81:00.0
/* attach a vdev af_packet device */
> attach net_af_packet,iface=eth0
/* detach the vdev af_packet device */
> detach net_af_packet
