[Libvirt-cim] [PATCH 00 of 27] Fix uses of get_typed_*()
This is a huge set that changes the semantics of get_typed_class() and
get_typed_instance() to take a reference class name for proper typing. I
have only smoke-tested it, but it fixes several issues with returning
incorrectly-typed instances that I know of.
A healthy amount of testing would be appreciated :)
