I'm happy with exposing Xen datatypes if that is the approach we want to
take but not with returning an xc_domaininfo_t.
I think the right compromise is therefore to declare that
libxl_dominfo.shutdown_reason contains the values defined in
xen/.../sched.h rather than a new libxl enum and retain the switch to
returning libxl_dominfo.
(Maybe that's what you meant anyhow)
Ian.
