When link is down at startup, the link_speed returned by DPDK
is 0. This results in un-optimized latency estimates in gen and lat.
With this fix, lat and gen do nothing until link_speed is
properly initialized, and use the right link speed in the fast path.

Jumbo frames are now supported through the addition of a "mtu"
parameter of the port in the config file.
Setting the mtu to a value higher than 1500 bytes will enable
the reception of jumbo frames.
In addition, the rte_eth_dev_set_mtu is now set for all pmds.
Finally, setting mbuf_size does not set MEMPOOL_F_NO_SPREAD
anymore. This option was only used for pure debugging.
Big packets can be received using two ways
- Using multiple "small" mbufs, i.e. around 2K. This is the default.
- Using one big mbuf holding the whole packet. This can be enabled
by setting a parameter mbuf_size in the receiving core configuration

This file describes flavors, flavor meta data and boot info.
All this info can be defined in the [Default] section and will then be
used by to create all VMs. This data can also be specified in individual
VM sections to overule the deault values per VM.

There is now a new file (rapidVMs.vms) describing how many VMs need
to be created. You can specify the same flavor values in the [DEFAULT]
section or specify specific flavors per VM.
The heat stack yaml files are removed.

Revert back part of commit 9fa316261d7d9
The function abs_diff was erroneously changed to diff_or_zero.
This function was supposed to measure the difference between rx and
tx time; when rx time overflowed and tx time not yet (i.e.
rx time ~= 0 and tx_time ~=UINT32_MAX, this function added UINT32_MAX
to rx_time. The name of the function was confusing and caused the
previous commit. Net effect of previous commit was that every four seconds
the minimum latency was 0
This commit reverse back to the original behavior, with a function name
diff_time.

Link_speed could be null when prox started with the ports down.
This was potentially causing a crash.
Another task will need to update link speed when the port come
up. Failing to do this results in less accurate latencies
(no extrapolation)

* Calculation of aboslute and relative dropped packets was wrong and is
now fixed.
* ./createrapid.py has now an extra option to select custom availability
zones for the different VMs.
* Fixed a typo to create the flavor: hw:cpu_thread_policy
* The generator config files have now the packet id & signature fields.
See PROX for more details on this.
* ./runrapid has now a new option --configonly. Default is False. If set
to True, all configuration files will be copied to the VMS, but the
tests are not started. This allows you to go to the VMs and manually
start PROX.
* In addition to the average latency, maximum latency is now also
displayed.

- Also changed lat_info.tx_packet_index to uint64_t,
so also did it for task_lat.prev_tx_packet_index and n_loss.
- Adjusted format strings accordingly, and fixed some other formats.
- Adjusted overflow increment to 2^32 (i.e. UINT32_MAX + 1).
- Replaced hard-coded 64 with ACCURACY_BUFFER_SIZE (still hard-coded
in handle_gen.c).

This feature will enable the possibility to have many cores
configured in a prox config file, and enable/disable them
through variables.
For instance, a [core $var1] section in a config file will
result in [core 1] if $var1 = 1; the whole section and section
content will be ignored if $var1=#
Before this implementation, [#core 1] or [core #] was already
treated as a commented out section (the whole section was
commented). But there was no way to define a variable $var = #
to comment a section through a variable.
Note that in today's implementation any non numerical
(except s, h, t, -) characteter in the [core] section header
(and not only #) will cause the section to be ignored.
It would probably be better to consider # (as maybe N/A and none)
as comments, and everything else as error. This is however not
supported by the change request.

Using l2 testing, where no ARP messages are being used, you can now run
a zero packet loss test. The binary search will continue to find the
speed where absolutely no packets have been lost during the test.
On top of that, the output has been reformatted to also show the
absolute and relative packet loss.
The *.test files have now 2 new parameters: drop_rate_treshold and accuracy.
When drop_rate_treshold is set to 0, this test will conclude successfull
when no packet has been lost whatsoever. If this is set to any other
number, the test will be successfull when the relative packet loss is
lower than drop_rate_treshold.
The new accuray parameter defines when the binary search will stop:
when the relative difference between the min and max of the search
window is lower than accuracy.
The irq testing is slightly modified to print the total number of
interrupts in a certain time bucket, not only as the number per second,
but when there is no interrupt whatsowever, we print '0' in stead of
'0.0'

When doing latency measurements PROX takes into account the
generation or reception of a bulk of packets. For instance, if
PROX receives at time T 4 packets, it knows that the first
packet was received by te NIC before T (the time to receive the other
3 packets, as they were received at maximum link speed).
So the latency data is decreased by the minimum time to receive those
3 packets.
For this PROX was using a default link speed of 10Gbps. This is wrong
for 1Gbps and 40Gbps networks, and was causing for instance issues
on 40 Gbps networks as extrapolating too much, resulting in either
too low latencies or negative numbers (visible as very high latencies).

irq mode can be used to show how a core is interrupted by other tasks.
This mode does not handle packets. It only loops reading tsc.
When the difference between two consecutive calls to rdtsc() is high
then it means the core was interrupted.
This task implementes the display, so that we can see a histogram of
interrupts as well as the maximum, per core.
Command line is also supported, through "show irq buckets" (too show
the intervals of each buckets, in micrcoseconds), and the stats
command line (showing the number of items in each buckets and the max)..

There were two issues identified in dump receive packets
- when the receive packets was going to be dropped (and not transmitted),
it was also printed as TX[255].
- a potential crash when using the dump function with modes like
lat which can receive more than MAX_RING_BURST.
Those issues have been fixed.

When doing latency measurements the generator can add a
32 bits signature in the packet at a specific location,
so that the receiver only uses the packets generated by the
generator and ignores packets generated for instance by a switch
The is particuly important for latency measurements as we use
data in the packets as timestamps, and packets generated elsewhere
would result in random latency for those packets.

PROX can stack different RX functions, so that they are executed
after each other.
This feature is for instance used to dump packets or to print
distribution of receive packets, without influencing the performance
of the rx functions when no dump or print is needed.
The previous implementation was wrong and causing some of the stacked
functions not to be executed. This was causing for instance issues
in latency measurement after enabling dumping packets.

L2fwd and swap has many options to set src mac. swap was supposed
to support the ability to use port mac, but config file parsing was
wrong. L2fwd was using port mac if a port was available and if
src mac=packet or if there was no src mac in the config.
Now l2fwd supports the following options
- "src mac=xx:xx:xx:xx:xx:xx" => this mac address is used as src mac.
- "src mac=packet" => the src mac is taken from the dst mac of the
received packet.
- "src mac=hw" => the src mac is taken from the mac address of the port,
if there is a physical port. Error otherwise.
- "src mac=no" => src mac kept untouched
- No "src mac" => same as "src mac=hw" if there is a physical port
and same as "src mac=packet" otherwise.
Default is (no "src mac") hence the mac is taken from the tx port if there
is one tx port and from the packet otherwise.
swap support is similar, except that it does not support "src mac=no".
