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).

15ab655835 qemu: block: Use correct format name when formatting overlay of qcow2+luks
A logic bug in the code creating overlays on existing images resulted
into wrongly using "luks" instead of "qcow2" for the backing format if
the backing image is an luks-encrypted qcow2. The special format munging
is needed only for raw luks images.

In practice the impact is not as critical as to use encrypted images in
the backing chain the user must fully describe the backing chain
including backing images to provide encryption keys, which overrides the
metadata recorded in the qcow2 header.

0af0b7d87d syntax-check: drop useless useless-if-before-free
With most of new code using g_auto for cleanup, contributors
are used to most of the free fucntions handling NULL gracefully.

Also, despite finding some occurrences in current codebase:
  avoid_if_before_free
  ~/libvirt/src/ch/ch_monitor.c: if (mon->vm)
        virObjectUnref(mon->vm);
  ~/libvirt/src/util/virresctrl.c: if (a_type->masks[cache])
        virBitmapFree(a_type->masks[cache]);
the check passes succesfully, because the script's logic:

  Exit status:
    0   one or more matches
    1   no match
    2   an error

does not play nicely with xargs:

  xargs exits with the following status:
       0      if it succeeds
     123      if any invocation of the command exited with status 1-125

The list of functions is also out of date - e.g. qemuCapsFree has
been renamed since.

This also helps eliminate one more Perl script per our programming
languages strategy: https://libvirt.org/programming-languages.html
