[Xen-devel] [PATCH v4 3/3] golang/xenlight: Implement DomainCreateNew

[George Dunlap <george.dunlap@xxxxxxxxxx>]

This implements the wrapper around libxl_domain_create_new().  With
the previous changes, it's now possible to create a domain using the
golang bindings (although not yet to unpause it or harvest it after it
shuts down).

v4:
- Remove hand-crafted constructor code, make non-RFC
