Certain device introspection crashes used to only happen if you were
using a certain machine, e.g. if the machine was using serial_hd() or
nd_table[], and a device was trying to use these in its instance_init
function, too.
To be able to catch these problems, let's extend the device-introspect
test to check the devices on all machine types, with and without the
"-nodefaults" parameter (since this makes a difference sometimes, too).
Since this is a rather slow operation, and most of the problems are
already handled by testing with the "none" machine only, the test with
all machines is only run in the "make check SPEED=slow" mode.

The tests that check something for all machine types currently spend
a lot of time checking old machine types (like "pc-i440fx-2.0" for
example). The chances that we find something new there in addition
to checking the latest version of a machine type are pretty low, so
we should not waste the time of the developers by testing this again
and again in the "quick" testing mode.
Thus let's add some code to determine whether we are testing a current
machine type or an old one, and only test the old types if we are
running in "SPEED=slow" mode.
This decreases the testing time quite a bit now, e.g. the qom-test
now finishes within 4 seconds for qemu-system-x86_64 instead of 30
seconds when testing all machines.

Because qtest does not support s390 channel I/O, s390 only performs smoke tests on
those few devices that do not have any functional tests. Therefore, every time we
add functional tests for a virtio device, the choice is between removing
those tests from the s390 suite (so that s390 actually _loses_ coverage)
or sprinkling the test with architecture checks.
This patch simply creates a ccw-specific test that only performs smoke tests on
all virtio-ccw devices. If channel I/O support is ever added to qtest and libqos,
then this file can go away. In the meanwhile, it simplifies maintenance and
makes sure that all virtio devices are tested.

When read() from the qtest socket or the QMP socket fails or EOFs, we
report "Broken pipe" and exit(1). This commonly happens when QEMU
crashes. It also happens when QEMU refuses to run because the test
passed it bad arguments. Sadly, we neglect to report either.
Improve this by calling abort() instead of exit(1), so kill_qemu()
runs, and reports how QEMU died. This improves error reporting to
something like
/x86_64/device/introspect/list: Broken pipe
tests/libqtest.c:129: kill_qemu() detected QEMU death from signal 6 (Aborted) (dumped core)
Three exit() remain in libqtest.c:
* In qmp_response(), when we can't parse a QMP reply read from the QMP
socket. Change to abort() for consistency.
* In qtest_qemu_binary(), when QTEST_QEMU_BINARY isn't in the
environment. This can only happen before we start QEMU. Leave
alone.
* In qtest_init_without_qmp_handshake(), when the fork()ed child fails
to execlp(). Leave alone.
exit() elsewhere are unlikely due to QEMU dying on us. If that should
turn out to be wrong, we can move kill_qemu() from @abrt_hooks to
atexit() or something.

[Commit message tweaked slightly]
In kill_qemu() we have an assert that checks that the QEMU process
didn't dump core:
assert(!WCOREDUMP(wstatus));
Unfortunately the WCOREDUMP macro here means the resulting message
is not very easy to comprehend on at least some systems:
ahci-test: tests/libqtest.c:113: kill_qemu: Assertion `!(((__extension__ (((union { __typeof(wstatus) __in; int __i; }) { .__in = (wstatus) }).__i))) & 0x80)' failed.
and it doesn't identify what signal the process took. What's more,
WCOREDUMP is not reliable - in some cases, setrlimit() coupled with
kernel dump settings can result in the flag not being set. It's
better to log ALL death by signal, instead of caring whether a core
dump was attempted (although once we know a signal happened, also
mentioning if a core dump is present can be helpful).
Furthermore, we are NOT detecting EINTR (while EINTR shouldn't be
happening if we didn't install signal handlers, it's still better
to always be robust).
Finally, even non-signal death with a non-zero status is suspicious,
since qemu's SIGINT handler is supposed to result in exit(0).
Instead of using a raw assert, print the information in an
easier to understand way:
/i386/ahci/sanity: tests/libqtest.c:129: kill_qemu() detected QEMU death from signal 11 (Segmentation fault) (core dumped)
(Of course, the really useful information would be why the QEMU
process dumped core in the first place, but we don't have that
by the time the test program has picked up the exit status.)

When you build QMP input manually like this
cmd = g_strdup_printf("{ 'execute': 'migrate',"
"'arguments': { 'uri': '%s' } }",
uri);
rsp = qmp(cmd);
g_free(cmd);
you're responsible for escaping the interpolated values for JSON. Not
done here, and therefore works only for sufficiently nice @uri. For
instance, if @uri contained a single "'", qobject_from_vjsonf_nofail()
would abort. A sufficiently nasty @uri could even inject unwanted
members into the arguments object.
Leaving interpolation into JSON to qmp() is more robust:
rsp = qmp("{ 'execute': 'migrate', 'arguments': { 'uri': %s } }", uri);
It's also more concise.

Commit ab45015a96 "qobject: Let qobject_from_jsonf() fail instead of

abort due to its use of &error_abort.
Its rationale for letting it fail is that all remaining users cope
fine with failure. Well, they're just fine with aborting, too; it's
what they do on failure.
Simply reverting the broken commit would bring back the unfortunate

like sprintf(), and qtest_qmp() etc. work like qobject_from_jsonf().
Spell that out in the comments.
Also add GCC_FMT_ATTR() to qtest_hmp() etc. so that the compiler can
flag incorrect use.
We have some cleanup work to do before we can do the same for
qtest_qmp() etc. This would get us the same better-than-nothing
checking we already have for qobject_from_jsonf(): common incorrect
uses of supported conversion specifications will be flagged
(e.g. passing a double for %d), but use of unsupported ones won't.

qtest_qmp_discard_response(...) is shorthand for
qobject_unref(qtest_qmp(...), except it's not actually shorter.
Moreover, the presence of these functions encourage sloppy testing.
Remove them from libqtest. Add them as macros to the tests that use
them, with a TODO comment asking for cleanup.

qtest_init() still uses the qtest_qmp_discard_response(s, "") hack to
receive the greeting, even though we have qtest_qmp_receive() since
commit 66e0c7b187. Put it to use.
Bonus: gets rid of an empty format string. A step towards
compile-time format string checking without triggering
-Wformat-zero-length.

blockdev-mirror with the same node for source and target segfaults
today: A node is in its own backing chain, so mirror_start_job() decides
that this is an active commit. When adding the intermediate nodes with
block_job_add_bdrv(), it starts the iteration through the subchain with
the backing file of source, though, so it never reaches target and
instead runs into NULL at the base.
While we could fix that by starting with source itself, there is no
point in allowing mirroring a node into itself and I wouldn't be
surprised if this caused more problems later.
So just check for this scenario and error out.

The -drive option serial was deprecated in QEMU 2.10. It's time to
remove it.
Tests need to be updated to set the serial number with -global instead

This reinstates commit a7aff6dd10,

The -drive options cyls, heads, secs and trans were deprecated in
QEMU 2.10. It's time to remove them.
hd-geo-test tested both the old version with geometry options in -drive
and the new one with -device. Therefore the code using -drive doesn't
have to be replaced there, we just need to remove the -drive test cases.
This in turn allows some simplification of the code.

The previous patch fixes a problem in which draining a block device
with more than one throttled request can make it wait first for the
completion of requests in other members of the same group.
This patch updates test_remove_group_member() in iotest 093 to
reproduce that scenario. This updated test would hang QEMU without the
fix from the previous patch.

A throttle group can have several members, and each one of them can
have several pending requests in the queue.
The requests are processed in a round-robin fashion, so the algorithm
decides the drive that is going to run the next request and sets a
timer in it. Once the timer fires and the throttled request is run
then the next drive from the group is selected and a new timer is set.
If the user tried to remove a drive from a group and that drive had a
timer set then the code was not taking care of setting up a new timer
in one of the remaining members of the group, freezing their I/O.
This problem was fixed in 6fccbb475b,
and this patch adds a new test case that reproduces this exact
scenario.
