This code provided inter-VM (2 cores per VM) throughput of
22Gbps using iperf through VPP (1 core) with 9k frames.
With the same setup and pktgen running on both sides, it
reached 5Mpps with no packets drop (Equivalent to before the patch).
During the tests the average vector length was about 1, which
likely means that VPP is not the bottleneck.
The patch also includes some generic functions for vlib buffers
allowing for chained buffer construction whether or not DPDK is enabled.

It also includes check to ensure that number of
per-cpu mheaps is not lower than number of cpus.

does not close the socket. Resulting in the main thread being stuck
in a tight infinite loop polling on the erronous socket.

The DPDK glue did not support cloned packets which do not
have a freelist handler. Add support for this case.

Limit buffer tracing to 50 in order to limit large output, unless
the user over rides the max "sh trace max <number>".
Add trace filtering, to be able to only trace packets that were
processed by a specific node or exclude packets processed by a node.
Example, only include packets processed by error-drop:
# trace filter include error-drop 1
# trace add dpdk-input 1000000
<wait for packets, to come in>
# show trace
