We currently create stub 'setcon', 'setcon_raw' and 'security_disable'
APIs in the securityselinuxhelper.c mock, which set env variables to
control how other mock'd libselinux APIs respond. These stubs merely
set some env variables, and we have no need to call these stubs from
the library code, only test code.
The 'security_disable' API is now deprecated in libselinux, so we
stubbing it generates compiler warnings. Rather than workaround that,
just stop stubbing these APIs and set the required env variables
directly. With this change, we now only mock API calls we actually
use from the library code.

Introduce capabilities based on qemu commit 'v9.1.0-803-g05adb38839'.
Notable changes:
- new 9.2 machine types
- 'gluster' disk backend deprecated
- 'reconnect' option of chardevs replaced by 'reconnect-ms'
- this includes test output changes happening in this patch
as 'reconnect' was deprecated in the same patch that
introduced 'reconnect-ms' and thus couldn't be changed
incrementally
- cpu flags:
- 'ibpb-brtype' added
- 'vmx-exit-secondary-ctls' added
- 'vmx-entry-load-rtit-ctl' added
- migration capabilities/parameters
- 'zero-blocks' deprecated
- 'multifd-qatzip-level' added
- 'pty' chardev backend gained 'path' attribute
- 'cris' and 'she4b' arches removed (from 'query-cpus-fast' data)

everywhere. Currently, users have two options:
1) configure <memory dumpCore=''/> in domain XML, or
2) configure dump_guest_core in qemu.conf
While these work, they may harm user experience as "things just
don't work" out of the box. Provide sane default in
virQEMUDriverConfigNew() so neither of two options is required.

If the configuration explicitly requests a specific type of
firmware image, be it pflash or ROM, we should ignore all images
that are not of that type.
If no specific type has been requested, of course, any type is
considered a match and the selection will be based upon the
other attributes.

This new test case covers the scenario in which the user
specifically asked for a read/write pflash image.
From the output files, we can see that the firmware selection
algorithm has picked a ROM image, which demonstrates the
presence of another bug. We're going to fix it with an upcoming
commit.

Sync with the edk2-20240524-4.fc39 package from Fedora.
The only notable change is that the inteltdx variant now declares
support for Secure Boot and is a ROM image instead of a stateless
pflash one.
The latter causes it to be considered eligible for the
configuration described by the firmware-auto-efi-rw test cases,
which now passes instead of failing.
Of course that doesn't make any sense, because a ROM image by
definition cannot be read/write. So this indicates the presence
of a bug in our firmware selection algorithm, which we're going
to address with an upcoming commit.

Now that we have a fake virtiofsd json descriptor in our vhost-user
test data, we can remove the explicitly specified binary and our
mocking will ensure this test won't be affected by the host state.
Also remove the locking options, since they were never supported
by the Rust version of virtiofsd.

The "modify" command allows to replace an existing record (its

duplicity or missing record detected, throw error.

The "modify" command allows to replace an existing Srv record
(some of its elements respectively: port, priority and weight).
The primary key used to choose the modify record is the remaining
parameters, only one of them is required. Not using some of these
parameters may cause duplicate records and error message. This
logic is there because of the previous implementation (Add and
Delete options) in the function.

Similarly to commit 2482801608 we can safely ignore connectionId,
portId and portgroupId in both XML and VMX as they are only a blind
pass-through between XML and VMX and an ethernet without such parameters
was spotted in the wild. On top of that even our documentation says the
whole VMWare Distrubuted Switch configuration is a best-effort.

mem_nodes[i].ndistances is written outside the loop causing an out-of-bounds
write leading to heap corruption.
While we are at it, the entire cleanup portion can be removed as it can be
handled in virDomainNumaFree. One instance of VIR_FREE is also removed and
replaced with g_autofree.
This patch also adds a testcase which would be picked up by ASAN, if this
portion regresses.

Under the test environment, driver->domainEventState is uninitialized. If a
disk gets dropped, it will attempt to queue an event which will cause a
segmentation fault. This crash does not occur during normal use.
This patch moves driver->domainEventState initialization from qemuhotplugtest
to qemuTestDriverInit in testutilsqemu (Credit goes to Michal Privoznik as he
had already provided the diff).
An additional test case is added to test dropping of disks with startupPolicy
set as optional.

The current hostdev parsing logic sets rawio or sgio even if the hostdev type
is not 'scsi'. The rawio field in virDomainHostdevSubsysSCSI overlaps with
wwpn field in virDomainHostdevSubsysSCSIVHost, consequently setting a bogus
pointer value such as 0x1 or 0x2 from virDomainHostdevSubsysSCSIVHost's
point of view. This leads to a segmentation fault when it attempts to free
wwpn.
While setting sgio does not appear to crash, it shares the same flawed logic
as setting rawio.
Instead, we ensure these are set only after the hostdev type check succeeds.
This patch also adds two test cases to exercise both scenarios.
