    Drop local g_autoptr definitions for generated code
    
    Sadly, GLib's autoptr cleanup macros cannot be detected by the C
    pre-processor, because they generate a function. This means that we are
    forced to bump up the dependency on GLib 2.49, in order to build against
    a newer version of gdbus-codegen.
