Add ability to target platforms to individually include user-mode
support for system calls from "stat" group of system calls.
This change is related to new nanoMIPS platform in the sense that
it supports a different set of "stat" system calls than any other
target. nanoMIPS does not support structures stat and stat64 at
all. Also, support for certain number of other system calls is
dropped in nanoMIPS (those are most of the time obsoleted system
calls).
Without this patch, build for nanoMIPS would fail.

the warning is turnend on by -Wimplicit-fallthrough. With this patch,
there will be no such warnings in target/mips directory. If such

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.)

qtest_qmp_device_add() and its wrappers interpolate into JSON as

* qtest_qmp_device_add() interpolates members into a JSON object.

* usb_test_hotplug() additionally interpolates strings and numbers

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.
Clean up the simple cases where we interpolate exactly a JSON value.

We have two flavors of vararg usage in qtest: qtest_hmp() etc. work
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.

This function returns a BDS's driver-specific options, excluding also
those from its children. Since we have just removed all children
options from bs->options there's no need to do this last step.
We allow references to children, though ("backing": "node0"), so those
we still have to remove.

If bdrv_reopen() succeeds then bs->explicit_options is updated with
the new values, but bs->options never changes.
Here's an example:
{ "execute": "blockdev-add",
"arguments": {
"driver": "qcow2",
"node-name": "hd0",
"overlap-check": "all",
"file": {
"driver": "file",
"filename": "hd0.qcow2"
}
}
}
After this, both bs->options and bs->explicit_options contain
"overlap-check": "all".
Now let's change that using qemu-io's reopen command:
(qemu) qemu-io hd0 "reopen -o overlap-check=none"
After this, bs->explicit_options contains the new value but
bs->options still keeps the old one.
This patch updates bs->options after a BDS has been successfully
reopened.

If a bdrv_reopen_multiple() call fails, then the explicit_options
QDict has to be deleted for every entry in the reopen queue. This must
happen regardless of whether that entry's bdrv_reopen_prepare() call
succeeded or not.
This patch simplifies the cleanup code a bit.

When bdrv_open_inherit() opens a BlockDriverState the options QDict
can contain options for some of its children, passed in the form of
child-name.option=value
So while each child is opened with that subset of options, those same
options remain stored in the parent BDS, leaving (at least) two copies
of each one of them ("child-name.option=value" in the parent and
"option=value" in the child).
Having the children options stored in the parent is unnecessary and it
can easily lead to an inconsistent state:
$ qemu-img create -f qcow2 hd0.qcow2 10M
$ qemu-img create -f qcow2 -b hd0.qcow2 hd1.qcow2
$ qemu-img create -f qcow2 -b hd1.qcow2 hd2.qcow2
$ $QEMU -drive file=hd2.qcow2,node-name=hd2,backing.node-name=hd1
This opens a chain of images hd0 <- hd1 <- hd2. Now let's remove hd1
using block_stream:
(qemu) block_stream hd2 0 hd0.qcow2
After this hd2 contains backing.node-name=hd1, which is no longer
correct because hd1 doesn't exist anymore.
This patch removes all children options from the parent dictionaries
at the end of bdrv_open_inherit() and bdrv_reopen_queue_child().
