[libvirt] [libvirt-glib 06/37] Use glib-mkenums to register enums with glib

[Christophe Fergeau]

We don't currently have any enum in our API, but we will need some.
This commit adds the generation of libvirt-gconfig-enum-types.[ch]
using glib-mkenums. These files will register the various enums
that will get added to libvirt-gconfig header files with glib.
