Cole Robinson eb4068cc47 xmlbuilder: Add infrastructure for parsing into subclasses
We already had this open coded in several classes with varying methods.
Now all someone has to do is

features = XMLChildProperty(CPUFeature)

The xmlbuilder code will pull the relevant xpath from the CPUFeature class,
handling parsing into instances of that class directly. The only
thing that needs to be manually added is the add_* remove_* functions.
