If we spy on the QMP commands instead, we don't need callers to remember
to pass it. Seems like a fair trade-off.
The one slightly weird bit is overloading this instance variable for
wait(), where we use it to mean "don't issue the qmp 'quit'
command". This means that wait() will "fail" if the QEMU process does
not terminate of its own accord.
In most cases, we probably did already actually issue quit -- some
iotests do this -- but in some others, we may be waiting for QEMU to
terminate for some other reason, such as a test wherein we tell the
guest (directly) to shut down.

We are going to drop group file. Define group in tests as a preparatory
step.
The patch is generated by
cd tests/qemu-iotests
grep '^[0-9]\{3\} ' group | while read line; do
file=$(awk '{print $1}' <<< "$line");
groups=$(sed -e 's/^... //' <<< "$line");
awk "NR==2{print \"# group: $groups\"}1" $file > tmp;
cat tmp > $file;
done

Like script_main, but doesn't require a single point of entry.
Replace all existing initialization sections with this drop-in replacement.
This brings debug support to all existing script-style iotests.

If a test has issued a quit command already (which may be useful to do
explicitly because the test wants to show its effects),
QEMUMachine.shutdown() should not do so again. Otherwise, the VM may
well return an ECONNRESET which will lead QEMUMachine.shutdown() to
killing it, which then turns into a "qemu received signal 9" line.

This patch adds a test where we cancel a throttled mirror job and
immediately close the VM before it can be cancelled. Doing so will
invoke bdrv_drain_all() while the mirror job tries to drain the
throttled node. When bdrv_drain_all_end() tries to lift its drain on
the throttle node, the job will exit and replace the current root node
of the BB drive0 (which is the job's filter node) by the throttle node.
Before the previous patch, this replacement did not increase drive0's
quiesce_counter by a sufficient amount, so when
bdrv_parent_drained_end() (invoked by bdrv_do_drained_end(), invoked by
bdrv_drain_all_end()) tried to end the drain on all of the throttle
node's parents, it decreased drive0's quiesce_counter below 0 -- which
fails an assertion.

This tests that concurrent requests are correctly drained before making
graph modifications instead of running into assertions in
bdrv_replace_node().
