nssocket forks and change netns pre-establishd by ip(8), serves its
socket descriptor to parent via nssocket(). Since this socket is
isolated, it can be used to create regression tests for conntrack.
This also adds a conntrack event testcase as a first user.
A ct_echo_event.sh script is provided to build and run this test
automatically:
# ./qa/ct_echo_event.sh
make: Entering directory...
...debug output like:
