[RFC PATCH 1/1] Add basic support for code coverage analysis

[Felix Moessbauer <felix.moessbauer@siemens.com>]

This patch adds basic support to get meaningful
code coverage statistics for some central components.
To keep things simple, we only focus on the parts that are
tested as part of the "fast-tests" suite.
This includes the lib as well as drivers that do not require
special hardware to be tested.

By providing the gcovr.cfg file in the project root,
modern versions of meson (>=0.63) can pass that information
to gcovr, making it possible to configure the coverage target
of meson.
This enables us to use the default meson coverage infrastructure
and customize it for the needs of the DPDK project.
