app/test: measure cycles per packet in Rx/Tx

The unit test can be used to measure cycles per packet in different rx/tx routines.
The NIC works in loopback mode. So it doesn't require test equipment to measure throughput.
As result, the unit test shows the average cycles per packet consuming.
When doing the test, make sure the link is UP.

Usage Example:
1. Run unit test app in interactive mode
    app/test -c f -n 4 -- -i
2. Run and wait for the result
    pmd_perf_autotest

There's option to choose rx/tx pair, default is vector.
    set_rxtx_mode [vector|scalar|full|hybrid]
Note: To get acurate scalar fast, please choose 'vector' or 'hybrid' without INC_VEC=y in config

It supports to measure standalone rx or tx.
Usage Example:
Choose rx or tx standalone, default is both
    set_rxtx_anchor [rxtx|rxonly|txonly]

It also supports to measure standalone RX burst cycles.
In this way, it won't repeat re-send received packets.
Now it measures two situations, poll before/after xmit(w or w/o desc. cache conflict)
Usage Example:
Set stream control mode, by default is continuous
    set_rxtx_sc [continuous|poll_before_xmit|poll_after_xmit]

is now reserved in rte_malloc heaps (because it needs to be
shared across DPDK processes). The first thing DPDK initializes

space in rte_malloc heap before allocating the mempool itself.
By default, rte_malloc allocates way more space than is necessary,
so under some conditions (namely, overall memory available is low)
this results in malloc heap eating up so much memory that log

i40e: fix configuration of Rx interrupt

Inside NIC RX interrupt is needed for single RX descriptor
write back. The fix is to correct the wrong configuration
of register 'I40E_QINT_RQCTL'.
Note that interrupt will be inside NIC only, that means it
will never be reported outside NIC hardware.
