As of 47503cc859 we are statically linking libtest_utils.a into
qemuhotplugmock.so (see the original commit for reasoning).
However, this breaks ASAN on older clang because now
qemuhotplugtest has two instances of virTestHostArch global
variable. One that comes from the binary itself (which also links
with libtest_utils.a) and the other from the mock. Resolve this
by making the variable static and introducing getter and setter.
Well, the former already exists (as virArchFromHost()) so only
the latter is needed.

And make callers check the return value as well. This helps error out early for
invalid environment variables.
That is desirable because it could lead to deadlocks. This can happen when
resetting logging after fork() reports translated errors because gettext
functions are not reentrant. Well, it is not limited to resetting logging after
fork(), it can be any translation at that phase, but parsing environment
variables is easy to make fail on purpose to show the result, it can also happen
just due to a typo.
Before this commit it is possible to deadlock the daemon on startup
with something like:
LIBVIRT_LOG_FILTERS='1:*' LIBVIRT_LOG_OUTPUTS=1:stdout libvirtd
where filters are used to enable more logging and hence make the race less rare
and outputs are set to invalid
Combined with the previous patches this changes
the following from:
...
<deadlock>
to:
...
libvirtd: initialisation failed
The error message is improved in future commits and is also possible thanks to
this patch.

Add support for deserializing the binary PCI/PCIe VPD format and storing
results in memory.
The VPD format is specified in "I.3. VPD Definitions" in PCI specs
(2.2+) and "6.28.1 VPD Format" PCIe 4.0. As section 6.28 in PCIe 4.0
notes, the PCI Local Bus and PCIe VPD formats are binary compatible
and PCIe 4.0 merely started incorporating what was already present in
PCI specs.
Linux kernel exposes a binary blob in the VPD format via sysfs since
v2.6.26 (commit 94e6108803469a37ee1e3c92dafdd1d59298602f) which requires

Memory on a NUMA node can have a side caches. Configuring these
for a domain was implemented in v6.6.0-rc1~249 and friends.
However, up until now mgmt applications did not really know what
values to pass because we were not exposing caches of the host.
With recent enough kernel these are exposed under sysfs and with
a bit of parsing we can extend our capabilities XML. The sysfs
structure is documented in kernel's
Documentation/admin-guide/mm/numaperf.rst and basically maps in
1:1 fashion to our virNumaCache structure.

When a test has a wrapper over main() (e.g. because it's
preloading some mock libraries). the main() is renamed to
something else (usually mymain()), and main() is generated by
calling one of VIR_TEST_MAIN() or VIR_TEST_MAIN_PRELOAD() macros.
This has a neat side effect - if mymain() returns an error a
short summary is printed, e.g.:
Some tests failed. Run them using:
VIR_TEST_DEBUG=1 VIR_TEST_RANGE=5-6 ./virtest
However, this detection only works if EXIT_FAILURE is returned by
mymain(). Document and enforce this limitation.

Historically, we declared pointer type to our types:
typedef struct _virXXX virXXX;
typedef virXXX *virXXXPtr;
But usefulness of such declaration is questionable, at best.
Unfortunately, we can't drop every such declaration - we have to
carry some over, because they are part of public API (e.g.
virDomainPtr). But for internal types - we can do drop them and
use what every other C project uses 'virXXX *'.
