The values in an enum live in a global namespace. That means if DPDK defines "RUNNING" it can't be used by another enum in an application using DPDK. To solve this add a prefix "LCORE_" to the enum values, and make them grammatically consistent. Also, simplify the inline thread_is_running() which is copied in softnic and ip_pipeline.
