[dpdk-dev] [PATCH] examples/helloworld: add output of core id and socket id

[Wei Dai <wei.dai@intel.com>]

Adding output of core id and socket id of each lcore/pthread
can help to understand their relationship.
And this can also help to examine the usage of the EAL lcore
settings like -c, -l and --lcore .
