OsinfoFeature is a new type intended to represent *guest* features. Its
XML representation is something towards the lines of:
<features>
<feature supported="false">cpu-hotplug</feature>
<feature>pci-device-hotplug</feature>
<feature>numa</feature>
</features>
Where supported is an optional attribute which has "true" as its default
value.
