libxl: add API wrapper for libxl_retrieve_domain_configuration

Browse Source 
Upcoming changes will use different LIBXL_API_VERSION variants.

Prepare libxl_retrieve_domain_configuration, which got a new parameter
"libxl_asyncop_how" in Xen 4.12. libvirt does not use this parameter.

No functional change intended.
