Copy public function pointers (rx_pkt_burst(), etc.) and related
pointers to internal data from rte_eth_dev structure into a
separate flat array. That array will remain in a public header.
The intention here is to make rte_eth_dev and related structures internal.
That should allow future possible changes to core eth_dev structures
to be transparent to the user and help to avoid ABI/API breakages.
The plan is to keep minimal part of data from rte_eth_dev public,
so we still can use inline functions for fast-path calls
(like rte_eth_rx_burst(), etc.) to avoid/minimize slowdown.
The whole idea beyond this new schema:
1. PMDs keep to setup fast-path function pointers and related data
inside rte_eth_dev struct in the same way they did it before.
2. Inside rte_eth_dev_start() and inside rte_eth_dev_probing_finish()
(for secondary process) we call eth_dev_fp_ops_setup, which
copies these function and data pointers into rte_eth_fp_ops[port_id].
3. Inside rte_eth_dev_stop() and inside rte_eth_dev_release_port()
we call eth_dev_fp_ops_reset(), which resets rte_eth_fp_ops[port_id]
into some dummy values.
4. fast-path ethdev API (rte_eth_rx_burst(), etc.) will use that new
flat array to call PMD specific functions.
That approach should allow us to make rte_eth_devices[] private
without introducing regression and help to avoid changes in drivers code.

The private headers are compiled internally with a C compiler.
Thus extern "C" declaration is useless in such files.

There is no reason for the DPDK libraries to all have 'librte_' prefix on
the directory names. This prefix makes the directory names longer and also
makes it awkward to add features referring to individual libraries in the
build - should the lib names be specified with or without the prefix.
Therefore, we can just remove the library prefix and use the library's
unique name as the directory name, i.e. 'eal' rather than 'librte_eal'
