We need to be able to cast from virObjectEventPtr to one of
its many subclasses. Some of these subclasses have 8 byte
alignment on 32-bit platforms, but virObjectEventPtr only
has 4 byte alignment.
Previously the virObject base class had 8 byte alignment
but this dropped to 4 byte when converted to inherit from
GObject. This introduces cast alignment warnings on 32-bit:
../../src/conf/domain_event.c: In function 'virDomainEventDispatchDefaultFunc':
../../src/conf/domain_event.c:1656:30: error: cast increases required alignment of target type [-Werror=cast-align]

Forcing 8-byte alignment on virObjectEventPtr removes the
alignment increase during casts to subclasses.

Similar to commits 55ce656463 and 6c17606b7c in the qemu driver, make
separate copies of persistent and live device config and normalize the MAC
address between the two. This avoids having different MAC address for the
persistent and live config, ensuring the device has the same address when
the persistent config takes affect after a VM restart.

Prior to 2621d48f00 "gnulib: delete all gnulib integration",
one could pass ./autogen.sh --no-git to prevent the libvirt build
system from running git submodule update.
This feature is needed by systems like the Xen Project CI which want
to explicitly control the revisions of every tree. These will
typically arrange to initialise the submodules check out the right
version of everything, and then expect the build system not to mess
with it any more.
Despite to the old documentation comments referring only to gnulib,
the --no-git feature is required not only because of gnulib but also
because of the other submodule, src/keycodemapdb.
(And in any case, even if it were no longer required because all the
submodules were removed, it ought ideally to have been retained as a
no-op for compaibility reasons.)
So restore the --no-git feature.
Because of the way the argument parsing of autogen.sh works, it is
easiest to recognise this option only if it comes first. This works
for the Xen Project CI, which has always passed this option first.
If something else is using this option (and hasn't introduced a
different workaround in the meantime), not in the first position,
then perhaps a more sophisticated approach will be needed. But I
think this will do for now.

Commit v3.10.0-182-g237f045d9a ("qemu: Ignore fallback CPU attribute
on reconnect") forced CPU 'fallback' to ALLOW, regardless of user
choice. This fixed a situation in which guests created with older
Libvirt versions, which used CPU mode 'host-model' in runtime, would
fail to launch in a newer Libvirt if the fallback was set to FORBID.
This would lead to a scenario where the CPU was translated to 'host-model'
to 'custom', but then the FORBID setting would make the translation
process fail.
PSeries can operate with 'host-model' in runtime due to specific PPC64
mechanics regarding compatibility mode. The update() implementation of
the cpuDriverPPC64 driver is a NO-OP if CPU mode is 'host-model', and
the driver does not implement translate(). The commit mentioned above
is causing PSeries guests to get their 'fallback' setting to ALLOW,
overwriting user choice, exposing a design problem in
qemuProcessRefreshCPU() - for PSeries guests, handling 'host-model'
as it is being done does not apply.
All other cpuArchDrivers implements update() and changes guest mode
to VIR_CPU_MODE_CUSTOM, meaning that PSeries is currently the only
exception to this logic. Let's make it official.
