Thomas Haller bb4b749595 clients/tests: don't wait for first job before scheduling parallel jobs 
Previously, the test would kick off 15 processes in parallel, but
the first job in the queue would block more processes from being
started.

That is, async_start() would only start 15 processes, but since none of
them were reaped before async_wait() was called, no more than 15 jobs
were running during the start phase. That is not a real issue, because
the start phase is non-blocking and queues all the jobs quickly. It's
not really expected that during that time many processes already completed.
Anyway, this was a bit ugly.

The bigger problem is that async_wait() would always block for the
first job to complete, before starting more processes. That means,
if the first job in the queue takes unusually long, then this blocks
other processes from getting reaped and new processes from being
started.

Instead, don't block only one one jobs, but poll them in turn for a
short amount of time. Whichever process exits first will be completed
and more jobs will be started.

In fact, in the current setup it's hard to notice any difference,
because all nmcli invocations take about the same time and are
relatively fast. That this approach parallelizes better can be seen
when the runtime of jobs varies stronger (and some invocations take
a notably longer time). As we later want to run nmcli under valgrind,
this probably will make a difference.

An alternative would be not to poll()/wait() for child processes,
but somehow get notified. For example, we could use a GMainContext
and watch child processes. But that's probably more complicated
to do, so let's keep the naive approach with polling.

#
# This test starts NetworkManager stub service in a user D-Bus session,
# and runs nmcli against it. The output is recorded and compared to a pre-generated
# expected output (clients/tests/test-client.check-on-disk/*.expected) which
# is also committed to git.
#
###############################################################################
#
# HOWTO: Regenerate output
#
# When adjusting the tests, or when making changes to nmcli that intentionally
# change the output, the expected output must be regenerated.
#
# $ make install
# # (step not required every time)
# # The test also compare the translated output, hence, the translation
# # file must be installed at the configured --prefix.
# # You don't need to type `make install` every time, but a suitable version
# # of translations must be installed. In practice, the tests only care about
# # Polish (pl) translations.
# # The important part is that translations work. Test
# # $ LANG=pl_PL.UTF-8 ./clients/cli/nmcli --version
# # also ensure that `locale -a` reports the Polish locale.
# $ rm -rf clients/tests/test-client.check-on-disk/*.expected
# # (step seldom required)
# # Sometimes, if you want to be sure that the test would generate
# # exactly the same .expected files, purge the previous version first.
# # This is only necessary, when you remove test from this file.
# $ NM_TEST_REGENERATE=1 make check-local-clients-tests-test-client
# # Set NM_TEST_REGENERATE=1 to regenerate all files.
# $ git diff ... ; git add ...
# # (optional step)
# # Inspect what changed, and whether it makes sense. Then commit changes
# # to git.

ENV_NM_TEST_CLIENT_NMCLI_PATH = 'NM_TEST_CLIENT_NMCLI_PATH'

# that you first install the translation in the right place. So, by default,
# if a test for a translation fails, it will mark the test as skipped, and not

# does not allow that multiple profiles *stay* connected at the same
# time, there is always the possibility that a profile is activating/active
# on a device, while also activating/deactivating in parallel.
