common_init_tbl is only used within this single CU, so it should be marked
static.
WARNS=6 also complained about the var defined by
`ATF_TC_WITH_CLEANUP(getastats);` being unused, which turns out to be
because it's not been hooked up in ATF_TP_ADD_TCS. kp@ did not immediately
recall any reason for this, and the case passes on my local system, so hook
it up.
Note that I've not yet set WARNS= 6 here. Investigation is underway to see
if we can feasibly default WARNS to 6 for src builds to catch directories
too deep to inherit a WARNS from the top-level subdirectories' Makefile.inc.
Those particular WARNS settings will be subsequently removed as they become
redundant with a more-global default.

In order to move python2 out of the test framework to avoid py2 vs. py3
confusions upgrade the remaining test cases using scapy to work with py3.
That means only one version of scapy needs to be installed in the CI system.
It also gives a path forward for testing i386 issues observed in the CI
system with some of these tests.
Fixes are:
- Use default python from environment (which is 3.x these days).
- properly ident some lines as common for the rest of the file to avoid
errors.
- cast the calculated offset to an int as the division result is considered
a float which is not accepted input.
- when comparing payload to a magic number make sure we always add the
payload properly to the packet and do not try to compare string in
the result but convert the data payload back into an integer.
- fix print formating.

Add a common test suite for the firewalls included in the base system. The test
suite allows common test infrastructure to test pf, ipfw and ipf firewalls from
test files containing the setup for all three firewalls.
Add the pass block test for pf, ipfw and ipf. The pass block test checks the
allow/deny functionality of the firewalls tested.

It's been reported that pf doesn't handle running out of available ports
for NAT correctly. It freezes until a state expires and it can find a
free port.
Test for this, by setting up a situation where only two ports are
available for NAT and then attempting to create three connections.
If successful the third connection will fail immediately. In an
incorrect case the connection attempt will freeze, also freezing all
interaction with pf through pfctl and trigger timeout.
