Each sample script sources functions.sh before parameters.sh
which makes $APPEND undefined when trapping EXIT no matter in
append mode or not. Due to this when sample scripts finished
they always do "pgctrl reset" which resets pktgen config.
So move trap to each script after sourcing parameters.sh
and trap EXIT explicitly.

All pktgen samples can send indefinitely num messages per thread by
setting the count option to 0(-n 0). If running sample with setting
count 0 and press Ctrl-C to stop this program, the program prints the
result of the execution so far. Currently, the samples besides
sample{3...5} don't work properly. Because Ctrl-C stops the script, not
just pktgen.
This is results of samples:
# DEV=eth0 DEST_IP=10.1.0.1 DST_MAC=00:11:22:33:44:55 ./pktgen_sample04_many_flows.sh -n 0
Running... ctrl^C to stop
^CDevice: eth0@0
Result: OK: 569657(c569538+d118) usec, 84650 (60byte,0frags)
148597pps 71Mb/sec (71326560bps) errors: 0
# DEV=eth0 DEST_IP=10.1.0.1 DST_MAC=00:11:22:33:44:55 ./pktgen_sample01_simple.sh -n 0
Running... ctrl^C to stop
^C
In order to solve this, this commit adds trap SIGINT. Also, this commit
changes control_c function to print_result to maintain consistency with
other samples.

To configure various complex flows we for sure can create custom
pktgen init scripts, but sometimes thats not that easy.
New "-a" (append) option in all the existing sample scripts allows
to append more "devices" into pktgen threads.
The most straightforward usecases for that are:
- using multiple devices. We have to generate full linerate on
all physical functions (ports) of our multiport device.
- pushing multiple flows (with different packet options)

Currently, kernel pktgen has the feature to specify destination
address range for sending packet. (e.g. pgset "dst_min/dst_max")
But on samples, each pktgen script doesn't have any option to achieve this.
This commit adds the feature to specify the destination address range with CIDR.
-d : ($DEST_IP) destination IP. CIDR (e.g. 198.18.0.0/15) is also allowed
# ./pktgen_sample01_simple.sh -6 -d fe80::20/126 -p 3000 -n 4
# tcpdump ip6 and udp
05:14:18.082285 IP6 fe80::99.71 > fe80::23.3000: UDP, length 16
05:14:18.082564 IP6 fe80::99.43 > fe80::23.3000: UDP, length 16
05:14:18.083366 IP6 fe80::99.107 > fe80::22.3000: UDP, length 16
05:14:18.083585 IP6 fe80::99.97 > fe80::21.3000: UDP, length 16

This commit changes variable names that can cause confusion.
For example, variable DST_MIN is quite confusing since the
keyword 'udp_dst_min' and keyword 'dst_min' is used with pg_ctrl.
On the following commit, 'dst_min' will be used to set destination IP,
and the existing variable name DST_MIN should be changed.
Variable names are matched to the exact keyword used with pg_ctrl.

Currently, kernel pktgen has the feature to specify udp destination port
for sending packet. (e.g. pgset "udp_dst_min 9")
But on samples, each of the scripts doesn't have any option to achieve this.
This commit adds the DST_PORT option to specify the target port(s) in the script.
-p : ($DST_PORT) destination PORT range (e.g. 433-444) is also allowed

This script simply does:
* Detect $DEV's NUMA node belonging.
* Bind each thread (processor of NUMA locality) with each $DEV queue's
irq affinity, 1:1 mapping.
* How many '-t' threads input determines how many queues will be utilized.
If '-f' designates first cpu id, then offset in the NUMA node's cpu list.
(Changes by Jesper: allow changing count from cmdline via '-n')
