As the 'restrict' keyword is recognized in C99, this patchset is to add a wrapper defining '__rte_restrict' which can be supported by all compilers. Then replace the existing 'restrict' and '__restrict' in different vpmds, and optimize vhost/virtio with restricted pointer aliasing for more aggressive loops vectorization.
The vhost/virtio optimization patches were benchmarked by running PVP case on ThunderX2 platform and showed positive performance results.
