This is a follow up on previous work by Kevin Laatz:
http://patches.dpdk.org/project/dpdk/list/?series=24658&state=*
This series is aimed at allowing DPDK applications to expose their CPU
usage stats in the DPDK telemetry under /eal/lcore/info. This is a much
more basic and naive approach which leaves the cpu cycles accounting
completely up to the application.
For reference, I have implemented a draft patch in OvS to use
rte_lcore_register_usage_cb() and report the already available busy
cycles information.

v9:
- Fixed changelog & version.map order.
- Updated with 64-bit integer telemetry functions.
- Refined docstrings (added notice about resetting the callback).
- Fixed accounting of total cycles in testpmd.
v8:
- Made /eal/lcore/info lcore_id argument parsing more robust.
