Because of using Reference(Uint64) directly in the idl - the python
bindings autogenerate these type-marshalling functions. It's not quite
clear how these are supposed to be implemented in a generic way! :)
There ought to be a builtin type for this ala libxl_uuid and other types
to generate correct bindings.
Gianni, I suppose I need a builtin for the complete libxl_cpumap type, not
only for the uint64_t array due to the size info which is needed to access
the array correctly.
I'm not sure how to translate this into the correct bindings. I think the
cpumap should be translated into a python list. Which methods do I need to
include in xc.c? Or would it be okay to add just some minimal dummy
functions and put in the functionality if needed?
