[RFC 0/6] Add a stricter headers check

[David Marchand <david.marchand@redhat.com>]

As explained in patch 6, the current headers check can not catch
issues when a public header includes an internal header.
Fixing this from meson does not seem an easy task.

The approach of this RFC is to reimplement the check in a Makefile invoked
out of DPDK (like what is done for external compilation of examples).
This has the advantage of being simple, and avoiding any (non intentional)
implicit include path coming from the meson framework.

As there was no easy way to distinguish "indirect" headers in an
installed DPDK, I chose to move those headers in a new sub directory
(patch 5).

Patch 1-4 fixes have not been marked as backport material as those bugs
seems minor/easy to fix externally (by either including missing headers,
or enabling enable_driver_sdk option).

For now, I left the check_includes= option untouched, as there may be
users of this check and this check still catches issues without
requiring to install DPDK.
