Fast mem and devices snapshots (#16)
* Run docker probe only if docker or podman are available

The docker probe uses "sudo -n" which can cause an e-mail with a security warning
each time when configure is run. Therefore run docker probe only if either docker
or podman are available.

That avoids the problematic "sudo -n" on build environments which have neither
docker nor podman installed.

* tests/avocado/machine_aspeed.py: Reduce noise on the console for SDK tests

The Aspeed SDK images are based on OpenBMC which starts a lot of
services. The output noise on the console can break from time to time
the test waiting for the logging prompt.

Change the U-Boot bootargs variable to add "quiet" to the kernel
command line and reduce the output volume. This also drops the test on
the CPU id which was nice to have but not essential.

* tests/avocado: introduce alpine virt test for CI

The boot_linux tests download and run a full cloud image boot and
start a full distro. While the ability to test the full boot chain is
worthwhile it is perhaps a little too heavy weight and causes issues
in CI. Fix this by introducing a new alpine linux ISO boot in
machine_aarch64_virt.

This boots a fully loaded -cpu max with all the bells and whistles in
31s on my machine. A full debug build takes around 180s on my machine
so we set a more generous timeout to cover that.

We don't add a test for lesser GIC versions although there is some
coverage for that already in the boot_xen.py tests. If we want to
introduce more comprehensive testing we can do it with a custom kernel
and initrd rather than a full distro boot.

* vhost: mask VIRTIO_F_RING_RESET for vhost and vhost-user devices

Commit 69e1c14aa2 ("virtio: core: vq reset feature negotation support")
enabled VIRTIO_F_RING_RESET by default for all virtio devices.

This feature is not currently emulated by QEMU, so for vhost and
vhost-user devices we need to make sure it is supported by the offloaded
device emulation (in-kernel or in another process).
To do this we need to add VIRTIO_F_RING_RESET to the features bitmap
passed to vhost_get_features(). This way it will be masked if the device
does not support it.

This issue was initially discovered with vhost-vsock and vhost-user-vsock,
and then also tested with vhost-user-rng which confirmed the same issue.
They fail when sending features through VHOST_SET_FEATURES ioctl or
VHOST_USER_SET_FEATURES message, since VIRTIO_F_RING_RESET is negotiated
by the guest (Linux >= v6.0), but not supported by the device.

* acpi: x86: move RPQx field back to _SB scope

Commit 47a373faa6b2 (acpi: pc/q35: drop ad-hoc PCI-ISA bridge AML routines and let bus ennumeration generate AML)
moved ISA bridge AML generation to respective devices and was using
aml_alias() to provide PRQx fields in _SB. scope. However, it turned
out that SeaBIOS was not able to process Alias opcode when parsing DSDT,
resulting in lack of keyboard during boot (SeaBIOS console, grub, FreeDOS).

While fix for SeaBIOS is posted
  https://mail.coreboot.org/hyperkitty/list/seabios@seabios.org/thread/RGPL7HESH5U5JRLEO6FP77CZVHZK5J65/
fixed SeaBIOS might not make into QEMU-7.2 in time.
Hence this workaround that puts PRQx back into _SB scope
and gets rid of aliases in ISA bridge description, so
DSDT will be parsable by broken SeaBIOS.

That brings back hardcoded references to ISA bridge
  PCI0.S08.P40C/PCI0.SF8.PIRQ
where middle part now is auto generated based on slot it's
plugged in, but it should be fine as bridge initialization
also hardcodes PCI address of the bridge so it can't ever
move. Once QEMU tree has fixed SeaBIOS blob, we should be able
to drop this part and revert back to alias based approach

* target/arm: Don't do two-stage lookup if stage 2 is disabled

In get_phys_addr_with_struct(), we call get_phys_addr_twostage() if
the CPU supports EL2.  However, we don't check here that stage 2 is
actually enabled.  Instead we only check that inside
get_phys_addr_twostage() to skip stage 2 translation.  This means
that even if stage 2 is disabled we still tell the stage 1 lookup to
do its page table walks via stage 2.

This works by luck for normal CPU accesses, but it breaks for debug
accesses, which are used by the disassembler and also by semihosting
file reads and writes, because the debug case takes a different code
path inside S1_ptw_translate().

This means that setups that use semihosting for file loads are broken
(a regression since 7.1, introduced in recent ptw refactoring), and
that sometimes disassembly in debug logs reports "unable to read
memory" rather than showing the guest insns.

Fix the bug by hoisting the "is stage 2 enabled?" check up to
get_phys_addr_with_struct(), so that we handle S2 disabled the same
way we do the "no EL2" case, with a simple single stage lookup.

* target/arm: Use signed quantity to represent VMSAv8-64 translation level

The LPA2 extension implements 52-bit virtual addressing for 4k and 16k
translation granules, and for the former, this means an additional level
of translation is needed. This means we start counting at -1 instead of
0 when doing a walk, and so 'level' is now a signed quantity, and should
be typed as such. So turn it from uint32_t into int32_t.

This avoids a level of -1 getting misinterpreted as being >= 3, and
terminating a page table walk prematurely with a bogus output address.

The logs in the gitlab-CI have a size constraint, and sometimes
we already hit this limit. The biggest part of the log then seems
to be filled by the qom-test, so we should decrease the size of
the output - which can be done easily by not printing the path
for each property, since the path has already been logged at the
beginning of each node that we handle here.

However, if we omit the path, we should make sure to not recurse
into child nodes in between, so that it is clear to which node
each property belongs. Thus store the children and links in a
temporary list and recurse only at the end of each node, when
all properties have already been printed.

* ui/gtk: prevent ui lock up when dpy_gl_update called again before current draw event occurs

A warning, "qemu: warning: console: no gl-unblock within" followed by
guest scanout lockup can happen if dpy_gl_update is called in a row
and the second call is made before gd_draw_event scheduled by the first
call is taking place. This is because draw call returns without decrementing
gl_block ref count if the dmabuf was already submitted as shown below.

(gd_gl_area_draw/gd_egl_draw)

        if (dmabuf) {
            if (!dmabuf->draw_submitted) {
                return;
            } else {
                dmabuf->draw_submitted = false;
            }
        }

So it should not schedule any redundant draw event in case draw_submitted is
already set in gd_egl_fluch/gd_gl_area_scanout_flush.

* hw/usb/hcd-xhci: Reset the XHCIState with device_cold_reset()

Currently the hcd-xhci-pci and hcd-xhci-sysbus devices, which are
mostly wrappers around the TYPE_XHCI device, which is a direct
subclass of TYPE_DEVICE.  Since TYPE_DEVICE devices are not on any
qbus and do not get automatically reset, the wrapper devices both
reset the TYPE_XHCI device in their own reset functions.  However,
they do this using device_legacy_reset(), which will reset the device
itself but not any bus it has.

Switch to device_cold_reset(), which avoids using a deprecated
function and also propagates reset along any child buses.

* hw/audio/intel-hda: don't reset codecs twice

Currently the intel-hda device has a reset method which manually
resets all the codecs by calling device_legacy_reset() on them.  This
means they get reset twice, once because child devices on a qbus get
reset before the parent device's reset method is called, and then
again because we're manually resetting them.

Drop the manual reset call, and ensure that codecs are still reset
when the guest does a reset via ICH6_GCTL_RESET by using
device_cold_reset() (which resets all the devices on the qbus as well
as the device itself) instead of a direct call to the reset function.

This is a slight ordering change because the (only) codec reset now
happens before the controller registers etc are reset, rather than
once before and then once after, but the codec reset function
hda_audio_reset() doesn't care.

This lets us drop a use of device_legacy_reset(), which is
deprecated.

1. qemu_cleanup() closes all drives, setting blk->root to NULL
2. qemu_cleanup() calls user_creatable_cleanup(), which results in a RAM
   block notifier callback because the memory-backend-file is destroyed.
3. blk_unregister_buf() is called by virtio-blk's BlockRamRegistrar
   notifier callback and undefined behavior occurs.

* vhost: enable vrings in vhost_dev_start() for vhost-user devices

Commit 02b61f38d3 ("hw/virtio: incorporate backend features in features")
properly negotiates VHOST_USER_F_PROTOCOL_FEATURES with the vhost-user
backend, but we forgot to enable vrings as specified in
docs/interop/vhost-user.rst:

    If ``VHOST_USER_F_PROTOCOL_FEATURES`` has not been negotiated, the
    ring starts directly in the enabled state.

    If ``VHOST_USER_F_PROTOCOL_FEATURES`` has been negotiated, the ring is
    initialized in a disabled state and is enabled by
    ``VHOST_USER_SET_VRING_ENABLE`` with parameter 1.

Some vhost-user front-ends already did this by calling
vhost_ops.vhost_set_vring_enable() directly:
- backends/cryptodev-vhost.c
- hw/net/virtio-net.c
- hw/virtio/vhost-user-gpio.c

But most didn't do that, so we would leave the vrings disabled and some
backends would not work. We observed this issue with the rust version of
virtiofsd [1], which uses the event loop [2] provided by the
vhost-user-backend crate where requests are not processed if vring is
not enabled.

Let's fix this issue by enabling the vrings in vhost_dev_start() for
vhost-user front-ends that don't already do this directly. Same thing
also in vhost_dev_stop() where we disable vrings.

* hw/nvme: fix aio cancel in format

There are several bugs in the async cancel code for the Format command.

Firstly, cancelling a format operation neglects to set iocb->ret as well
as clearing the iocb->aiocb after cancelling the underlying aiocb which
causes the aio callback to ignore the cancellation. Trivial fix.

Secondly, and worse, because the request is queued up for posting to the
CQ in a bottom half, if the cancellation is due to the submission queue
being deleted (which calls blk_aio_cancel), the req structure is
deallocated in nvme_del_sq prior to the bottom half being schedulued.

Fix this by simply removing the bottom half, there is no reason to defer
it anyway.

* Sync pc on breakpoints

* tests/qtest/migration-test: Fix unlink error and memory leaks

When running the migration test compiled with Clang from Fedora 37
and sanitizers enabled, there is an error complaining about unlink():

 ../tests/qtest/migration-test.c:1072:12: runtime error: null pointer
  passed as argument 1, which is declared to never be null
 /usr/include/unistd.h:858:48: note: nonnull attribute specified here
 SUMMARY: UndefinedBehaviorSanitizer: undefined-behavior
  ../tests/qtest/migration-test.c:1072:12 in
 (test program exited with status code 1)
 TAP parsing error: Too few tests run (expected 33, got 20)

The data->clientcert and data->clientkey pointers can indeed be unset
in some tests, so we have to check them before calling unlink() with
those.

While we're at it, I also noticed that the code is only freeing
some but not all of the allocated strings in this function, and
indeed, valgrind is also complaining about memory leaks here.
So let's call g_free() on all allocated strings to avoid leaking
memory here.

* target/s390x/tcg: Fix and improve the SACF instruction

The SET ADDRESS SPACE CONTROL FAST instruction is not privileged, it can be
used from problem space, too. Just the switching to the home address space
is privileged and should still generate a privilege exception. This bug is
e.g. causing programs like Java that use the "getcpu" vdso kernel function
to crash (see https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=990417#26 ).

While we're at it, also check if DAT is not enabled. In that case the
instruction is supposed to generate a special operation exception.

Expected AML change:
ISA devices under separate _SB.PCI0.ISA scope are moved
directly under Device(ISA) node.

Example from PC machine, and q35 have similar changes:

For both pc and q35, there is but a small difference between this
DSDT.acpierst and the corresponding DSDT. In both cases, the changes
occur under the hiearchy:

    Scope (\_SB)
    {
        Scope (PCI0)
        {

which leads me to believe that the change to the DSDT was needed
due to the introduction of the ERST PCI device.

And is explained in detail by Ani Sinha:
I have convinced myself of the changes we see in the DSDT tables.
On i440fx side, we are adding a non-hotpluggable pci device on slot 3.
So the changes we see are basically replacing an empty hotpluggable
slot on the pci root port with a non-hotplugggable device.
On q35, bsel on pcie root bus is not set (its not hotpluggable bus),
so the change basically adds the address enumeration for the device.
