x86/libxc: add an arch domain config parameter to xc_domain_create
With the addition of HVMlite the hypervisor now always requires a non-null
arch domain config, which is different between HVM and PV guests.
Add a new parameter to xc_domain_create that contains a pointer to an arch
domain config. If the pointer is null, create a default arch domain config
based on guest type.
Fix all the in-tree callers to provide a null arch domain config in order to
mimic previous behaviour.
