[PATCH 2/3] eal: uninline rte_str_to_size

[Dmitry Kozlyuk <dmitry.kozliuk@gmail.com>]

There is no reason for rte_str_to_size() to be inline.
Move the implementation out of <rte_common.h>.
Export it as a stable ABI because it always has been public.

Now <rte_common.h> doesn't need to #include <ctypes.h> and <stdlib.h>,
but removing them breaks some DPDK code, may break user code too.
I'm not sure what is the compatibility policy in this regard.
If such a breakage is allowed, I'd remove includes and fix DPDK code.
