XENMEM_set_memory_map taking a struct { domain, range_list }. This can
initialise a small array embedded in the domain structure.
Plumb through libxc and python xc.so. Probably make the call from
LinuxImageHandler (or whatever it's called) in image.py.
Done.
Most of the pain is in the tools plumbing (in particular arg parsing in the
python wrapper).
