Add a new function object_resolve_and_typecheck(), whose purpose is
to look up the object at a given QOM path, confirm that it is the
expected type, and return it. This is similar to the existing
object_resolve_path_type(), but it insists on a non-ambiguous path.
We were already using this functionality internally to object.c as
part of the object_resolve_link() function, so this patch implements
the new function by pulling the link-property specific parts out of
the more generic resolve-and-typecheck part.
The motivation for this function is that we want to allow devices to
provide an array of link properties; for that we will need to be able
to provide the expected type of the linked object in a different way
to the single-item link properties.
