This test case checks that expanding NUMA distance works. On

Commit 82576d8f35 used a string "on" to enable the 'pmem' property.
This is okay for the command line visitor, but the property is declared
as boolean in qemu and thus it will not work when using QMP.
Modify the type to boolean. This changes the command line, but
fortunately the command line visitor in qemu parses both 'yes' and 'on'
as true for the property.

Firstly, SEV is present only on AMD, so we can safely assume x86.
Secondly, the problem with looking up capabilities in the cache by arch
is that it's using virHashSearch with a callback to find the right
capabilities and get the binary name from it as well, but since the
cache is empty, it will return NULL and we won't get the corresponding
binary name out of the lookup either. Then, during the cache validation
we try to create a new cache entry for the emulator, but since we don't
have the binary name, nothing gets created.
Therefore, virQEMUCapsCacheLookupDefault is used to fix this issue,
because it doesn't rely on the capabilities cache to construct the
emulator binary name.

The semantics of the backup operation don't strictly require that all
disks being backed up are part of the same incremental part (when a disk
was checkpointed/backed up separately or in a different VM), or even
they may not have a previous checkpoint at all (e.g. when the disk
was freshly hotplugged to the vm).
In such cases we can still create a common checkpoint for all of them
and backup differences according to configuration.
This patch adds a per-disk configuration of the checkpoint to do the
incremental backup from via the 'incremental' attribute and allows
perform full backups via the 'backupmode' attribute.
Note that no changes to the qemu driver are necessary to take advantage
of this as we already obey the per-disk 'incremental' field.

Although libvirt itself uses g_malloc0() and friends, which exit when
there isn't enouogh memory, libxml2 uses standard malloc(), which just
returns NULL on OOM - this means we must check for NULL on return from
any libxml2 functions that allocate memory.
xmlBufferCreate(), for example, might return NULL, and we don't always
check for it. This patch adds checks where it isn't already done.
(NB: Although libxml2 has a provision for changing behavior on OOM (by
calling xmlMemSetup() to change what functions are used to
allocating/freeing memory), we can't use that, since parts of libvirt
code end up in libvirt.so, which is linked and called directly by
applications that may themselves use libxml2 (and may have already set
their own alternate malloc()), e.g. drivers like esx which live totally
in the library rather than a separate process.)
