This is an optional helper, so why not.

Another help for applications would be to allow initializing DPDK
without the need of passing or building argc/argv arguments.
I think we could add new functions rte_eal_init_*().
Example:
	rte_eal_init_prepare()
	rte_eal_init_memory(memory parameters)
	rte_eal_init_devices(devargs)
	rte_eal_init_threads()

It should be possible to rebuild rte_eal_init()
using above smaller functions to keep the big old
rte_eal_init with argc/argv for compatibility.
