Test 067 from qemu-iotests is executing QMP commands to hotplug
and hot-unplug disks, devices and blockdevs. Because the power
of the text-based test harness is limited, it is actually limiting
the checks that it does, for example by skipping DEVICE_DELETED
events.
tests/qtest already has a similar test, drive_del-test.c.
We can merge them, and even reuse some of the existing code in
drive_del-test.c. This will improve the quality of the test by
covering DEVICE_DELETED events and testing multiple architectures
(therefore covering multiple PCI hotplug mechanisms as well as s390x
virtio-ccw).
The only difference is that the new test will always use null-co:// for
the medium rather than qcow2 or raw, but this should be irrelevant for
what the test is covering. For example there are no "qemu-img check"
runs in 067 that would check that the file is properly closed.
The new tests requires PCI hot-plug support, so drive_del-test
is moved from qemu-system-ppc to qemu-system-ppc64.

Do not just trust the HMP commands to create and delete the drive, use
query-block to check that this is actually the case.

Let test use the new functionality for buffering events.
The only remaining users of qtest_qmp_receive_dict are tests
that fuzz the QMP protocol.
Tested with 'make check-qtest'.

In the next patch a new version of qtest_qmp_receive will be
reintroduced that will buffer received qmp events for later
consumption in qtest_qmp_eventwait_ref
No functional change intended.

qmp_assert_error_class() does more than just assert: it also unrefs
the @rsp argument. Rename to qmp_expect_error_and_unref() to reduce
confusion.

The tests directory itself is pretty overcrowded, and it's hard to
see which test belongs to which test subsystem (unit, qtest, ...).
Let's move the qtests to a separate folder for more clarity.
