[Libvirt-cim] [PATCH 00 of 12] Finish out the conversion to classname connections

This fixes the remaining uses of lv_connect() (except for ComputerSystemIndication, which I'll deal with later). A quick poke seems to indicate that things still work, but testing would be good. Next, I will work on get_typed_instance(), which also needs a per-classname change so that we don't return Xen_foo instances for non-xen cases. There are also a lot of fixes needed to prevent classes from returning instances for the incorrect platform. These would be any that don't depend on a valid libvirt connection for their work.
