As of libssh commit of libssh-0.11.0~70 [1] the
ssh_channel_get_exit_status() function is deprecated and a new
one is introduced instead: ssh_channel_get_exit_state().
It's not a drop-in replacement, but it's simple enough.
Adapt our libssh handling code to this change.

This mostly reverts commit 65491a2dfe.
There was a bug introduced in glib 2.67.0 which impacted libvirt with
clang causing -Wincompatible-pointer-types-discards-qualifiers warnings.
This was actually fixed quite quickly in 2.67.1 with
https://gitlab.gnome.org/GNOME/glib/-/merge_requests/1719
Our workaround was then broken with glib 2.81.1 due to commit
14b3d5da9019150d821f6178a075d85044b4c255 changing the signature of the
(private) macro we were overriding.
Since odd-number glib releases are development snapshots, and the
original problem was only present in 2.67.0 and no other releases,
just drop the workaround entirely.

Latest qemu will be dropping some very old machine types (2.0 - 2.3) and
some of our tests use them. As in none of the cases the test actually
needs given machine type, switch them to 'pc' instead.

modern syntax for NUMA memory specification, but the test is testing a
different aspect, thus we can modernize this.

This excercises the old-style NUMA memory commandline used with 5.0 and

-numa node,nodeid=0,cpus=0-7,mem=107 \
-numa node,nodeid=1,cpus=8-15,mem=107 \
in contrast to the modern syntax:
-smp 16,sockets=2,dies=1,clusters=1,cores=4,threads=2 \
-object '{"qom-type":"memory-backend-ram","id":"ram-node0","size":112197632}' \

-numa node,nodeid=1,cpus=8-15,memdev=ram-node1 \
which is tested by the 'cpu-numa1' test case where this was copied from.
This test is added so that other irrelevant test can be modernized.

Depending on timing between QEMU and libvirt an attempt to resume failed
post-copy migration could immediately report a failure in post-copy
phase again even though the migration actually resumed and is
progressing just fine.
This is caused by QEMU reporting the original migration state (i.e.,
postcopy-paused) until migration is successfully resumed and QEMU
switches to postcopy-active. QEMU 9.1 introduced a new
postcopy-recover-setup migration state which is entered immediately
after requesting migration to be resumed and we can reliably wait for
the migration to either continue or fail without being confused by the
old state.

Thing about vshReadlineInit() is - it's called multiple times.
The first time from vshInit(), when @ctl was filled only
partially (most notably, before any argv parsing is done, hence
ctl->imode is set to false). The second time after argv parsing,
from virshInit() -> vshInitReload(). In here, ctl->imode might
have changed and thus vshReadlineInit() can't exit early - it
needs to set up stuff for interactive mode (history basically).
To allow vshReadlineInit() to be called again,
vshReadlineDeinit() must set @autoCompleteOpaque to NULL.

The s390(x) machines never supported ACPI. That didn't stop users
enabling ACPI in their config. As of libvirt-9.2 (98c4e3d073) with new
enough qemu we reject configs which require ACPI, but qemu can't satisfy
it.
This breaks migration of existing VMs with the old wrong configs to new
libvirt installations.
To address this introduce a post-parse fixup removing the ACPI flag
specifically for s390 machines which do enable it in the definition.
The advantage of doing it in post-parse, rather than simply relaxing the
ABI stability check to allow users providing an fixed XML when migrating
(allowing change of the ACPI flag for s390 in ABI stability check, as it
doesn't impact ABI), is that only the destination installation needs to
be patched in order to preserve migration.
To mitigate the disadvantage of simply stripping it from all s390(x)
configs the hack is not applied when defining or starting a new domain
from the XML, to preserve the error about unsupported configuration.

The whole point of pstore device is that the guest writes crash
dumps into it. But the way SELinux label is set on the
corresponding file warrants RO access only. This is due to a
copy-paste from code around: kernel/initrd/DTB/SLIC - these are
RO indeed, but pstore MUST be writable too. In a sense it's
closer to NVRAM/disks - hence set imagelabel on it.

So far we are relying on QEMU or sysadmin to create the file for
pstore. This is suboptimal as in the case of the former we can
not set proper seclabels (there's nothing to set seclabels on
until QEMU is started).
Therefore, make sure the file is created before launching QEMU
and that it has the correct size.
