2f168d0708 migration: Route more error paths
vmstate_save_state is called in lots of places.
Route error returns from the easier cases back up;  there are lots
of more complex cases where their own error paths need fixing.

44b1ff319c migration: pre_save return int
Modify the pre_save method on VMStateDescription to return an int
rather than void so that it potentially can fail.

Changed zillions of devices to make them return 0; the only
case I've made it return non-0 is hw/intc/s390_flic_kvm.c that already
had an error_report/return case.

Note: If you add an error exit in your pre_save you must emit
an error_report to say why.

f3adefb2ce qemu-io: Drop write permissions before read-only reopen
qemu-io provides a 'reopen' command that allows switching from writable
to read-only access. We need to make sure that we don't try to keep
write permissions to a BlockBackend that becomes read-only, otherwise
things are going to fail.

This requires a bdrv_drain() call because otherwise in-flight AIO
write requests could issue new internal requests while the permission
has already gone away, which would cause assertion failures. Draining
the queue doesn't break AIO requests in any new way, bdrv_reopen() would
drain it anyway only a few lines later.

b1149c1a2a iotests: use virtio aliases for 067
The default cpu model on s390x does not provide zPCI, which is
not yet wired up on tcg. Moreover, virtio-ccw is the standard
on s390x.

Using virtio-scsi will implicitly pick the right device, so just
switch to that for simplicity.

05b4cd5d3c qemu-iotests: Add missing -machine accel=qtest
A basic set of qemu options is initialised in ./common:

    export QEMU_OPTIONS="-nodefaults -machine accel=qtest"

However, two test cases (172 and 186) overwrite QEMU_OPTIONS and neglect
to manually set '-machine accel=qtest'. Add the missing option for 172.
186 probably only copied the code from 172, it doesn't actually need to
overwrite QEMU_OPTIONS, so remove that in 186.

0789700019 tests/boot-sector: Increase timeout to 600 seconds
If QEMU has been compiled with the flags --enable-tcg-interpreter and
--enable-debug, the guest is running incredibly slow. The pxe boot test
can take up to 400 seconds when testing the pseries ppc64 machine. While
we should still look for ways to speed up the test on the pseries machine,
it's better to increase the timeout in this test to 600 seconds anyway to
allow the test to pass successfully now with this unusal configuration
already.

7b899f4dd5 qtest: Avoid passing raw strings through hmp()
hmp() passes its string argument through the sprintf() family;
with a proper attribute, gcc -Wformat warns us when we do something
dangerous like passing a non-constant format string.  Fortunately,
all our strings were safe, but checking whether the string can
contain an unintended % is easy to avoid and therefore worth doing.

4fb609adc9 libqtest: Remove dead qtest_instances variable
Prior to commit 063c23d9, we were tracking a list of parallel
qtest objects, in order to safely clean up a SIGABRT handler
only after the last connection quits.  But when we switched to
more of glib's infrastructure, the list became dead code that
is never assigned to.

f94b3f64e6 test-qga: Kill broken and dead QGA_TEST_SIDE_EFFECTING code
Back when the test was introduced, in commit 62c39b307, the
test was set up to run qemu-ga directly on the host performing
the test, and defaults to limiting itself to safe commands.  At
the time, it was envisioned that setting QGA_TEST_SIDE_EFFECTING
in the environment could cover a few more commands, while noting
the potential danger of those side effects running in the host.

But this has NEVER been tested: if you enable the environment
variable, the test WILL fail.  One obvious reason: if you are not
running as root, you'll probably get a permission failure when
trying to freeze the file systems, or when changing system time.
Less obvious: if you run the test as root (wow, you're brave), you
could end up hanging if the test tries to log things to a
temporarily frozen filesystem.  But the cutest reason of all: if
you get past the above hurdles, the test uses invalid JSON in
test_qga_fstrim() (missing '' around the dictionary key 'minimum'),
and will thus fail an assertion in qmp_fd().

Rather than leave this untested time-bomb in place, rip it out.
Hopefully, as originally envisioned, we can find an opportunity
to test an actual sandboxed guest where the guest-agent has
full permissions and will not unduly affect the host running
the test - if so, 'git revert' can be used if desired, for
salvaging any useful parts of this attempt.

4446158a1a tests: Fix broken ivshmem-server-msi/-irq tests
Broken with commit b4ba67d9a7025 ("libqos: Change PCI accessors to take
opaque BAR handle") a while ago, but nobody noticed since the tests are
not run by default: The msix_pba_bar is not correctly initialized
anymore if bir_pba has the same value as bir_table. With this fix,
"make check SPEED=slow" should work fine again.
