40bfeae134 iotests: make qemu_io_log() check return codes by default
Just like qemu_img_log(), upgrade qemu_io_log() to enforce a return code
of zero by default.

72cfb937b8 iotests: remove qemu_io_silent() and qemu_io_silent_check().
Like qemu-img, qemu-io returning 0 should be the norm and not the
exception. Remove all calls to qemu_io_silent that just assert the
return code is zero (That's every last call, as it turns out), and
replace them with a normal qemu_io() call.

qemu_io_silent_check() appeared to have been unused already.

37094b6dd5 python: rename qemu.aqmp to qemu.qmp
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"
name.

da9d88d8e6 iotests.py: Filters for VM.run_job()
Allow filters for VM.run_job(), and pass the filters given to

(Use this opportunity to annotate VM.run_job()'s parameter types;
unfortunately, for the filter, I could not come up with anything better
than Callable[[Any], Any] that would pass mypy's scrutiny.)

At one point, a plain string is logged, so the filters passed to it must
work fine with plain strings.  The only filters passed to it at this
point are the ones from VM.blockdev_create(), which are
filter_qmp_test_files() (by default) and 207's filter_hash().  Both
cannot handle plain strings yet, but we can make them by amending
filter_qmp() to treat them as plain values with a None key.

8f685ac391 iotests: make qemu_img_log and img_info_log raise on error
Add a `check: bool = True` parameter to both functions and make their
qemu_img() invocations raise on error by default.

users of img_info_log:
206, 207, 210, 211, 212, 213, 237, 242, 266, 274, 302

users of qemu_img_log:
044, 209, 274, 302, 304

iotests 242 and 266 need to use check=False for their negative tests.
iotests 206, 210, 211, 212, 213, 237, 274 and 302 continue working
normally.

As of this commit, all calls to QEMU_IMG made from iotests enforce a
return code of zero by default unless explicitly disabled or suppressed
by passing check=False or with an exception handler.

1670ae7af6 iotests: add qemu_img_map() function
Add a qemu_img_map() function by analogy with qemu_img_measure(),
qemu_img_check(), and qemu_img_info() that all return JSON information.

Replace calls to qemu_img_pipe('map', '--output=json', ...) with this
new function, which provides better diagnostic information on failure.

Note: The output for iotest 211 changes, because logging JSON after it
was deserialized by Python behaves a little differently than logging the
raw JSON document string itself.
(iotests.log() sorts the keys for Python 3.6 support.)

qemu_img_json() is a new helper built on top of qemu_img() that tries to

In the event that the return code is negative (the program crashed), or
the code is greater than zero and did not produce valid JSON output, the
VerboseProcessError raised by qemu_img() is re-raised.

In the event that the return code is zero but we can't parse valid JSON,
allow the JSON deserialization error to be raised.

569131d585 iotests: fortify compare_images() against crashes
Fortify compare_images() to be more discerning about the status codes it
receives. If qemu_img() returns an exit code that implies it didn't
actually perform the comparison, treat that as an exceptional
circumstance and force the caller to be aware of the peril.

If a negative test is desired (perhaps to test how qemu_img compare
behaves on malformed images, for instance), it is still possible to
catch the exception in the test and deal with that circumstance
manually.

2882ccf86a iotests: make qemu_img raise on non-zero rc by default
re-write qemu_img() as a function that will by default raise a
VerboseProcessException (extended from CalledProcessException) on
non-zero return codes. This will produce a stack trace that will show
the command line arguments and return code from the failed process run.

Users that want something more flexible (there appears to be only one)
can use check=False and manage the return themselves. However, when the
return code is negative, the Exception will be raised no matter what.
This is done under the belief that there's no legitimate reason, even in
negative tests, to see a crash from qemu-img.

1a8fcca03f iotests: Write test output to TEST_DIR
Drop the use of OUTPUT_DIR (test/qemu-iotests under the build
directory), and instead write test output files (.out.bad, .notrun, and
.casenotrun) to TEST_DIR.

With this, the same test can be run concurrently without the separate
instances interfering, because they will need separate TEST_DIRs anyway.
Running the same test separately is useful when running the iotests with
various format/protocol combinations in parallel, or when you just want
to aggressively exercise a single test (e.g. when it fails only
sporadically).

Putting this output into TEST_DIR means that it will stick around for
inspection after the test run is done (though running the same test in
the same TEST_DIR will overwrite it, just as it used to be); but given
that TEST_DIR is a scratch directory, it should be clear that users can
delete all of its content at any point.  (And if TEST_DIR is on tmpfs,
it will just disappear on shutdown.)  Contrarily, alternative approaches
that would put these output files into OUTPUT_DIR with some prefix to
differentiate between separate test runs might easily lead to cluttering
OUTPUT_DIR.

(This change means OUTPUT_DIR is no longer written to by the iotests, so
we can drop its usage altogether.)

The __del__ handler is a safety net for when something goes so wrong in
a test that e.g. the tearDown() method is not called (e.g. setUp()
launches the QSD, but then launching a VM fails).  We do not want the
QSD to continue running after the test has failed, so __del__() will
take care to kill it.

22e29bcea1 iotests.py: qemu_img*("create"): support IMGOPTS='compression_type=zstd'
Adding support of IMGOPTS (like in bash tests) allows user to pass a
lot of different options. Still, some may require additional logic.

Now we want compression_type option, so add some smart logic around it:
ignore compression_type=zstd in IMGOPTS, if test want qcow2 in
compatibility mode. As well, ignore compression_type for non-qcow2
formats.

Note that we may instead add support only to qemu_img_create(), but
that works bad:

1. We'll have to update a lot of tests to use qemu_img_create instead
   of qemu_img('create'). (still, we may want do it anyway, but no
   reason to create a dependancy between task of supporting IMGOPTS and
   updating a lot of tests)

2. Some tests use qemu_img_pipe('create', ..) - even more work on
   updating

3. Even if we update all tests to go through qemu_img_create, we'll
   need a way to avoid creating new tests using qemu_img*('create') -
   add assertions.. That doesn't seem good.

So, let's add support of IMGOPTS to most generic
qemu_img_pipe_and_status().

3bd2b942d9 iotests.py: img_info_log(): rename imgopts argument
We are going to support IMGOPTS environment variable like in bash
tests. Corresponding global variable in iotests.py should be called
imgopts. So to not interfere with function argument, rename it in
advance.

206dc47548 iotests: Conditionally silence certain AQMP errors
AQMP likes to be very chatty about errors it encounters. In general,
this is good because it allows us to get good diagnostic information for
otherwise complex async failures.

For example, during a failed QMP connection attempt, we might see:

+ERROR:qemu.aqmp.qmp_client.qemub-2536319:Negotiation failed: EOFError
+ERROR:qemu.aqmp.qmp_client.qemub-2536319:Failed to establish session: EOFError

This might be nice in iotests output, because failure scenarios
involving the new QMP library will be spelled out plainly in the output
diffs.

For tests that are intentionally causing this scenario though, filtering
that log output could be a hassle. For now, add a context manager that
simply lets us toggle this output off during a critical region.

(Additionally, a forthcoming patch allows the use of either legacy or
async QMP to be toggled with an environment variable. In this
circumstance, we can't amend the iotest output to just always expect the
error message, either. Just suppress it for now. More rigorous log
filtering can be investigated later if/when it is deemed safe to
permanently replace the legacy QMP library.)

af6d4c56e1 iotests: add 'qemu' package location to PYTHONPATH in testenv
We can drop the sys.path hacking in various places by doing
this. Additionally, by doing it in one place right up top, we can print
interesting warnings in case the environment does not look correct. (See
next commit.)

If we ever decide to change how the environment is crafted, all of the
"help me find my python packages" goop is all in one place, right in one
function.

Silences a new pylint warning. The dangers of *not* doing this are
somewhat unclear; I believe the file object gets garbage collected

non-deterministic. Maybe this is a valid warning, but if there are
consequences of not doing it, I am not aware of them at present.

Because the python script does not know in advance the valgrind
PID to assign to the log file name, use the "%p" flag in valgrind
log file name that automatically puts the process PID at runtime.
