Hi community,
I would like to introduce library for measuring load of some arbitrary jobs. It
can be used to profile every kind of job sets on any arbitrary execution unit or
tasking library.

In provided l2fwd-headroom example I demonstrate how to use this library to
select optimal rx burst poll time. Jobs are selected by using existing rte_timer
library calls. This example does no limit possible schemes on which this library
can be used.

PATCH v4 changes:
 - use proper branch fof generating patch.

PATCH v3 changes:
 - Fix spelling.

PATCH v2 changes:
 - Remove jobs management/callback from library to not duplicate tasking library
   behaviour.
 - Cleenup/remove useless statistics.
 - Rework example application to use rte_timer library for jobs selection.
 - Introduce new app parameter '-l' for automatic thousands separating in stats.
 - More readable statistics format.
