A forthcoming commit updates qemu_io() to raise an exception on non-zero
return by default, and changes its return type.
In preparation, simplify some calls to qemu_io() that assert that
specific error message strings do not appear in qemu-io's
output. Asserting that all of these calls return a status code of zero
will be a more robust way to guard against failure.

The 'read' commands to qemu-io were malformed, and this invocation only
worked by coincidence because the error messages were identical. Oops.
There's no point in checking the patterning of the reference image, so
just check the empty image by itself instead.
(Note: as of this commit, nothing actually enforces that this command
completes successfully, but a forthcoming commit in this series will
enforce that qemu_io() must have a zero status code.)

Now that we are fully switched over to the new QMP library, move it back
over the old namespace. This is being done primarily so that we may
upload this package simply as "qemu.qmp" without introducing confusion
over whether or not "aqmp" is a new protocol or not.
The trade-off is increased confusion inside the QEMU developer
tree. Sorry!
Note: the 'private' member "_aqmp" in legacy.py also changes to "_qmp";
not out of necessity, but just to remove any traces of the "aqmp"

We don't have to maintain compatibility with both QMP libraries anymore,
so we can just remove the old exception. While we're here, take
advantage of the extra fields present in the VMLaunchFailure exception
that machine.py now raises.
(Note: I'm leaving the logging suppression here unchanged. I had
suggested previously we use filters to scrub the PID out of the logging
information so it could just be diffed as part of the iotest output, but
that meant *always* scrubbing PID from logger output, which defeated the
point of even offering that information in the output to begin with.
Ultimately, I decided it's fine to just suppress the logger temporarily.)

One clear problem with how qcow2's refcount structure rebuild algorithm
used to be before "qcow2: Improve refcount structure rebuilding" was
that it is prone to failure for qcow2 images on block devices: There is
generally unused space after the actual image, and if that exceeds what
one refblock covers, the old algorithm would invariably write the
reftable past the block device's end, which cannot work. The new
algorithm does not have this problem.
Test it with three tests:
(1) Create an image with more empty space at the end than what one
refblock covers, see whether rebuilding the refcount structures
results in a change in the image file length. (It should not.)
(2) Leave precisely enough space somewhere at the beginning of the image
for the new reftable (and the refblock for that place), see whether
the new algorithm puts the reftable there. (It should.)
(3) Test the original problem: Create (something like) a block device
with a fixed size, then create a qcow2 image in there, write some
data, and then have qemu-img check rebuild the refcount structures.
Before HEAD^, the reftable would have been written past the image
file end, i.e. outside of what the block device provides, which
cannot work. HEAD^ should have fixed that.
("Something like a block device" means a loop device if we can use
one ("sudo -n losetup" works), or a FUSE block export with
growable=false otherwise.)

An iotest's 'paused' condition is fickle; it will be reported as true
whenever the job is drained, for example, or when it is in the process
of completing.
030 and 041 contain such checks, we should replace them by checking the
job status instead. (As was done for 129 in commit f9a6256b48
for the 'busy' condition.)
Additionally, when we want to test that a job is paused on error, we
might want to give it some time to actually switch to the paused state.
Do that by waiting on the corresponding JOB_STATUS_CHANGE event. (But
only if they are not already paused; the loops these places are in fetch
all VM events, so they may have already fetched that event from the
queue.)

When the stream block job cuts out the nodes between top and base in
stream_prepare(), it does not drain the subtree manually; it fetches the
base node, and tries to insert it as the top node's backing node with
bdrv_set_backing_hd(). bdrv_set_backing_hd() however will drain, and so
the actual base node might change (because the base node is actually not
part of the stream job) before the old base node passed to
bdrv_set_backing_hd() is installed.
This has two implications:
First, the stream job does not keep a strong reference to the base node.
Therefore, if it is deleted in bdrv_set_backing_hd()'s drain (e.g.
because some other block job is drained to finish), we will get a
use-after-free. We should keep a strong reference to that node.
Second, even with such a strong reference, the problem remains that the
base node might change before bdrv_set_backing_hd() actually runs and as
a result the wrong base node is installed.
Both effects can be seen in 030's TestParallelOps.test_overlapping_5()
case, which has five nodes, and simultaneously streams from the middle
node to the top node, and commits the middle node down to the base node.
As it is, this will sometimes crash, namely when we encounter the
above-described use-after-free.
Taking a strong reference to the base node, we no longer get a crash,
but the resuling block graph is less than ideal: The expected result is
obviously that all middle nodes are cut out and the base node is the
immediate backing child of the top node. However, if stream_prepare()
takes a strong reference to its base node (the middle node), and then
the commit job finishes in bdrv_set_backing_hd(), supposedly dropping
that middle node, the stream job will just reinstall it again.
Therefore, we need to keep the whole subtree drained in
stream_prepare(), so that the graph modification it performs is
effectively atomic, i.e. that the base node it fetches is still the base
node when bdrv_set_backing_hd() sets it as the top node's backing node.
Verify this by asserting in said 030's test case that the base node is
always the top node's immediate backing child when both jobs are done.

As part of moving all python iotest invocations of qemu-img onto a
single qemu_img() implementation, remove a few lingering uses of
qemu_img_pipe() from outside of iotests.py itself.
Several cases here rely on the knowledge that qemu_img_pipe() suppresses
*all* output on a successful case when the command being issued is
'create'.
065: This call's output is inspected, but it appears as if it's expected
to succeed. Replace this call with the checked qemu_img() variant
instead to get better diagnostics if/when qemu-img itself fails.
237: "create" call output isn't actually logged. Use qemu_img_create()
instead, which checks the return code. Remove the empty lines from
the test output.
296: Two calls;
-create: Expected to succeed. Like other create calls, the output
isn't actually logged. Switch to a checked variant
(qemu_img_create) instead. The output for this test is
a mixture of both test styles, so actually replace the
blank line for readability.
-amend: This is expected to fail. Log the output.

iotests.py and will be removed in subsequent patches.

All isabus_dev_print() did was to print up to two IRQ numbers per
device. This is redundant if the IRQ numbers are present as QOM
properties (see e.g. the modified tests/qemu-iotests/172.out).
Now that the last devices relying on isabus_dev_print() had their IRQ
numbers QOM'ified, the contribution of this function ultimately became
redundant. Remove it.

This validates that connections to an NBD server where the certificate
hostname does not match will fail. It further validates that using the
new 'tls-hostname' override option can solve the failure.

Introduce a filter for the output of qemu-nbd export list so it can be
reused in multiple tests.
The filter is a bit more permissive that what test 241 currently uses,
as its allows printing of the export count, along with any possible
error messages that might be emitted.

Some tests will want to use 'localhost' instead of '127.0.0.1', and
some will use the image options syntax rather than the classic URI
syntax.

When developing an I/O test it is typical to add some logic to the
test script, run it to view the output diff, and then apply the
output diff to the reference file. This can be drastically simplified
by letting the test runner update the reference file in place.
By setting 'QEMU_IOTESTS_REGEN=1', the test runner will report the
failure and show the diff, but at the same time update the reference
file. So next time the I/O test is run it will succeed.
Continuing to display the diff when updating the reference gives the
developer a chance to review what was changed.
