Commits 7b706f33 and 4acb7887 introduced some compound type *Free
wrappers in order to use them with VIR_DEFINE_AUTOPTR_FUNC. However,
since those were not used in the code right away, Clang complained about
unused functions (static ones that are defined by the macro above).
This patch puts the defined functions in use.

Technically, it was never used ever since commit @f4d06ca8 introduced
it, but the fact that we called VIR_FREE on it was enough for Clang to
never complain about it.

It is increasingly likely that some distro is going to change the
default "x86" machine type in QEMU from "pc" to "q35". This will
certainly break existing applications which write their XML on the
assumption that it is using a "pc" machine by default. For example they'll
lack a IDE CDROM and get PCIe instead of PCI which changes the topology
radically.

Libvirt promises to isolate applications from hypervisor changes that
may cause incompatibilities, so we must ensure that we always use the
"pc" machine type if it is available. Only use QEMU's own reported
default machine type if "pc" does not exist.

This issue is not x86-only, other arches are liable to change their
default machine, while some arches don't report any default at all
causing libvirt to pick the first machine in the list. Thus to
guarantee stability to applications, declare a preferred default
machine for all architectures we currently support with QEMU.

Note this change assumes there will always be a "pc" alias as long as a
versioned "pc-XXX" machine type exists. If QEMU were to ship a "pc-XXX"
machine type but not provide the "pc" alias, it is too hard to decide
which to default so. Versioned machine types are supposed to be
considered opaque strings, so we can't apply any sensible ordering
ourselves and QEMU isn't reporting the list of machines in any sensible
ordering itself.

Since commit ae83e02f#l3393 the
newPowerInfo pointer itself is used to track the ownership of the
AutoStartPowerInfo object to make Coverity understand the code better.
This broke the code that unset some members of the AutoStartPowerInfo
object that should not be freed the normal way.

Instead, transfer ownership of the AutoStartPowerInfo object to the
HostAutoStartManagerConfig object before filling in the values that
need special handling. This allows to free the AutoStartPowerInfo
directly without having to deal with the special values, or to let
the old (now restored) logic handle the special values again.

order to do that it calls virRandomBytes() to fill the integer
with random bytes and then masks out everything but requested

effectively, requesting 32 random bis or more always return 0
