samples: pktgen: add trap SIGINT for printing execution result
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.

of this option at "sample04" and "sample05".
In order to support IPv6 option, this commit adds logic related to IPv6
option.

samples: pktgen: new append mode
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.

This commit adds CIDR parsing and IP validate helper function to parse
single IP or range of IP with CIDR. (e.g. 198.18.0.0/15)
Validating the address should be preceded prior to the parsing.
Helpers will be used in prior to set target address in samples/pktgen.

samples: pktgen: fix proc_cmd command result check logic
Currently, proc_cmd is used to dispatch command to 'pg_ctrl', 'pg_thread',
'pg_set'. proc_cmd is designed to check command result with grep the
"Result:", but this might fail since this string is only shown in
'pg_thread' and 'pg_set'.
This commit fixes this logic by grep-ing the "Result:" string only when
the command is not for 'pg_ctrl'.
For clarity of an execution flow, 'errexit' flag has been set.
To cleanup pktgen on exit, trap has been added for EXIT signal.

Since commit 0f06a6787e05 ("samples: Add an IPv6 '-6' option to the

IPv6 with pktgen.
Thus, there is no longer a reason to keep the older sample scripts around.
