[dpdk-dev] [PATCH v3 1/5] eal: add internal flag indicating init has completed

[Anatoly Burakov <anatoly.burakov@intel.com>]

Currently, primary process initialization is finalized by setting
the RTE_MAGIC value in the shared config. However, it is not
possible to check whether secondary process initialization has
completed. Add such a value to internal config.
