[PATCH v1 03/12] libxl: add API wrapper for libxl_domain_shutdown

[Olaf Hering <olaf@xxxxxxxxx>]

Upcoming changes will use different LIBXL_API_VERSION variants.

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

No functional change intended.
