Previously we were ignoring "nodeset" attribute for hugepage pages
if there was no guest NUMA topology configured in the domain XML.
Commit <fa6bdf6afa878b8d7c5ed71664ee72be8967cdc5> partially fixed
that issue but it introduced a somehow valid regression.
In case that there is no guest NUMA topology configured and the
"nodeset" attribute is set to "0" it was accepted and was working
properly even though it was not completely valid XML.
This patch introduces a workaround that it will ignore the nodeset="0"
only in case that there is no guest NUMA topology in order not to
hit the validation error.
After this commit the following XML configuration is valid:
<memoryBacking>
<hugepages>
<page size='2048' unit='KiB' nodeset='0'/>
</hugepages>
</memoryBacking>
but this configuration remains invalid:
<memoryBacking>
<hugepages>
<page size='2048' unit='KiB' nodeset='0'/>
<page size='1048576' unit='KiB'/>
</hugepages>
</memoryBacking>
The issue with the second configuration is that it was originally
working, however changing the order of the <page> elements resolved
into using different page size for the guest. The code is written
in a way that it expect only one page configured and always uses only
the first page in case that there is no guest NUMA topology configured.

The virCapabilitiesDomainDataLookupInternal() is given a list of
parameters representing the desired domain characteristics. It then has
to look throught the capabilities to identify an acceptable match.
The virCapsDomainDataCompare() method is used for filtering out
candidates which don't match the desired criteria. It is called
primarily from the innermost loops and as such is doing many repeated
checks. For example if architcture and os type were checked at the top
level loop the two inner loops could be avoided entirely. If emulator
and domain type were checked in the 2nd level loop the 3rd level loop
can be avoided too.
This change thus removes the virCapsDomainDataCompare() method and puts
suitable checks at the start of each loop to ensure it executes the
minimal number of loop iterations possible. The code becomes clearer to
understand as a nice side-effect.

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.

When a variable of type virPerfPtr is declared using VIR_AUTOPTR,
the function virPerfFree will be run automatically on it when it
goes out of scope.
