[RFC PATCH 00/19] Fix building much of DPDK with -Wshadow

[Bruce Richardson <bruce.richardson@intel.com>]

As flagged in bugs #1742, #1743 and others, much of DPDK fails to build
when -Wshadow flag is passed to the build. This patchset fixes many
issues of this nature, but not all, in the hopes we can move towards
enabling that warning flag globally for DPDK in future. This patchset
fixes the following components in DPDK:

* all libraries
* Intel drivers
* testpmd

The following build now works on my system after this set is applied:

  meson setup -Denable_drivers=net/intel/* -Denable_apps=test-pmd --werror -Dc_args=-Wshadow build-shadow && ninja -C build-shadow
