This is a follow up on previous work by Kevin Laatz:

http://patches.dpdk.org/project/dpdk/list/?series=24658&state=*

This is a much more basic and naive approach which leaves the busy
cycles percentage completely up to the application.

This series is aimed at allowing DPDK applications to expose their CPU
busy cycles ratio in the DPDK telemetry under /eal/lcore/info.

I have left it as RFC since calculating busy cycles can be
a controversial topic.

For reference, I have implemented a draft patch in OvS to use
rte_lcore_register_busy_percent_cb() and return the already available
busy cycles information:

  eal: add lcore info in telemetry
  eal: allow applications to report their cpu utilization
  testpmd: add show lcores command
  testpmd: report lcore usage
