Add new unittest-like mechanism which uses scapy to craft custom
packets and a set of assertions to check how ipsec-secgw example
application is processing them. Python3 with scapy module is
required by pkttest.sh to run test scripts.
A new mechanism is used to test IPv6 transport mode traffic with
header extensions (trs_ipv6opts.py).
Fix incomplete test log problem by disabling buffering of ipsec-secgw
standard output with stdbuf application.
