A number of passt/pasta testcases have initial steps which are just about
building images or other assets we need for the test proper. Repeating
these for each test run can be quite costly.
This patch makes a start on moving this sort of test asset building to
a separate phase before running the tests proper. For now just add a
Makefile to handle the asset building (although it doesn't build
anything yet), and make the path where we'll be building the assets
available to the tests.

...there are no 'test' directives in demo, and this causes a
script failure.

Now that we have pane_status to check the success of commands issued to
panes, we can more easily check for the success of the 'which' commands
used to check tool availability, rather than constructing, then parsing
special "skip" output.

When we use pane_wait to wait for a command issued to a tmux pane to finish
we have no idea whether the command succeeded or not. This means that the
test scripts can keep running long after the point something vital has
failed, making it difficult to work out what went wrong.
Add a new pane_status command that checks for success of the issued command
and use it in most places instead of pane_wait. We still need explicit
pane_wait where we're gathering explicit output with pane_parse, because
the way we check the status with 'echo $?' means we lose track of that
output.

[sbrivio:
- instead of quitting the script, make a test fail if a command
issued in a pane fails during a test, and loop until the status code is
numeric in pane_status() as a hack to make it a bit more robust
- retain usage of pane_wait() in iperf3 and teardown functions as we
interrupt iperf3, passt, and pasta, so a non-zero exit code is expected
- drop bogus ns_{1,2}_wait() calls in teardown_two_guests(), those
functions were never implemented
- use pane_status() for "guest" test directives too

Most commands issued during the testing scripts aren't explicitly checked
for errors. Therefore, if they fail, the shell will just keep on
executing. This makes it difficult to figure out where things started
going wrong if things fall over.
Run the whole script with the set -e mode so that it will exit in the case
of any (unchecked) failing command. To make this work we do need to add
explicit checks / fallbacks for some commands which we expect to fail.

[sbrivio: use sh -e instead of setting -e later, so that we don't miss
anything before set -e is issued]

The DEBUG option for tests/run enables debugging options to passt/pasta,
however that doesn't help with debugging the test scripts themselves, which
are fairly fragile.
Extend the DEBUG option so it also prints information on each command in
the test scripts to make it easier to work out where things are falling
over.

For distribution tests, we'll repeat some tests frequently. Add a
'def' directive that starts a block, ended by 'endef', whose
execution can then be triggered by simply giving its name as a
directive itself.

Sometimes tests run a few seconds longer than expected, wait a few
