Many of these includes can be removed from this file, as they are
already included elsewhere (eg. rte_common.h via rte_dmadev.h).
For example, you could remove: ctype.h, stdint.h, stdlib.h, rte_errno.h,
rte_lcore.h, rte_memory.h, rte_malloc.h, rte_dev...
Please run test-meson-builds.sh after removing to make sure there are no
missing dependencies.
