  This series adds trace points for functions in the ethdev library.
The trace points are added in ethdev, flow, mtr and tm files.

v4:
 - Adds tracepoint function to emit char array. Also adds the
   test case.
 - Resolved review comments on "ethdev: add trace point" patch.
   This patch is divided into 2 patches to minimize per patch
   size.
 - From the earlier version (v3), few tracepoints in ethdev,
   flow, mtr, tm are made as fast path tracepoints. For the 
   tracepoint which i was unsure, i have made it as fastpath.
   All the fast path tracepoints can be found in 
   rte_ethdev_trace_fp.h and rte_ethdev_trace_fp_burst.h.
   All the slow path tracepoints can be found in rte_ethdev_trace.h.
 - Capturing of return value is added to tracepoint in ethdev.
   For flow, mtr and tm these changes are still yet to bde done.
   Will do it in the next versions.
 - Moved the trace functions from INTERNAL to EXPERIMENTAL in
   version.map.

v3:
 - Moved the trace functions from EXPERIMENTAL to INTERNAL in
   version.map.
 - Moved trace functions call to the end, in ethdev and flow trace.
 - Added code to print the input value of features in
   rte_eth_trace_rx_metadata_negotiate().
 - Added code to capture return value in flow trace.
