We've got multiple random open-coded versions. Switch to the helper
function which doesn't report errors as they'd be mostly wrong as the

Additionally this avoids use of 'host-model' with DO_TEST_CAPS_LATEST in

c7f3a1f787 qemu: simplify machine-type check for implicit floppy controller
Q35 machine types 2.3 and older had an integrated floppy controller.

Support for these machine types was removed by QEMU commit

  commit 86165b499edf8b03bb2d0e926d116c2f12a95bfe
      q35: Remove old machine versions
  git describe: v2.5.0-1530-g86165b499e contains: v2.6.0-rc0~76^2~4

In libvirt, we have bumped the minimum QEMU version to 2.11:

  commit b4cbdbe90b
    qemu: Formally deprecate support for qemu < 2.11
  git describe: v7.3.0-13-gb4cbdbe90b contains: v7.4.0-rc1~300

Since this QEMU version only supports Q35 machine versions 2.4+,
remove the code dealing with older ones.

fa8f99bbee conf: snapshot/checkpoint: Rewrite 'AlignDisk' logic to appease clang
New clang has a false-positive about value of 'olddisks' being unused
after being set. This is clearly wrong because we want to use
'g_autofree' to clear it later.

While I'm against modifying good code for the sake of bad static
analysis in this case it's not obvious that we depend on the lifetime of
'olddisks' being needed until the end of the function as we store
pointers into it into the hash table and later copy them out.

Rewrite the code by assigning to 'olddisks' earlier and then using
'olddisks' in the loop, so it's clear where the lifetime of the objects
ends, and this should also silence the warning.

78d4c12b8c virhostmem: Handle numactl-less build in hugepages allocation/reporting
When using 'virsh freepages' or 'virsh allocpages' then
virHostMemGetFreePages() or virHostMemAllocPages() is called,
respectively. But the following may happen: libvirt was built
without numactl support and thus a fake NUMA node was constructed
for capabilities, which means that startCell is going to be 0.
But we can't blindly pass startCell = 0 to virNumaGetPageInfo()
nor virNumaSetPagePoolSize() because they would operate over node
specific path (/sys/devices/system/node/nodeX) rather than NUMA
agnostic path (/sys/kernel/mm/hugepages/) and we are not
guaranteed that the former exists (kernel might have been built
without NUMA support).
