[PATCH v2 4/8] convert code to object_new_dynamic() where appropriate

["Daniel P. Berrangé" <berrange@redhat.com>]

In cases where object_new() is not being passed a static, const
string, the caller cannot be sure what type they are instantiating.
There is a risk that instantiation could fail, if it is an abstract
type.

Convert such cases over to use object_new_dynamic() such that they
are forced to expect failure. In some cases failure can be easily
propagated, but in others using &error_abort or &error_fatal will
maintain existnig behaviour.
