[dpdk-dev] [PATCH] eal: promote some experimental functions as stable

[Thomas Monjalon <thomas@monjalon.net>]

The function rte_eal_cleanup() was introduced more than one year ago,
in DPDK 18.02. It is no longer experimental, allowing
pdump, proc-info and hotplug_mp apps to not need any experimental API.

The function rte_ctrl_thread_create() was introduced one year ago
in DPDK 18.05. It is no longer experimental, allowing
KNI PMD and TEP example to not need any experimental API.

The functions rte_socket_count() and rte_socket_id_by_idx() were
introduced one year ago in DPDK 18.05. They are no longer experimental.

The function rte_dev_is_probed() was introduced half a year ago
in DPDK 18.11. It is no longer experimental.
