[dpdk-dev] [PATCH v2] eal: promote some service core functions to stable

[Gage Eads]

The functions rte_service_may_be_active(), rte_service_lcore_attr_get(),
and rte_service_attr_reset_all() were introduced nearly a year ago in DPDK
18.08. They can be considered non-experimental for the 19.08 release.

rte_service_may_be_active() is used by the sw PMD, and this commit allows
it to not need any experimental API.

v2: add allow-experimental flag back to eventdev, which still uses an
    experimental cryptodev API
