    gdbus tool: print GVariant errors in context
    
    Use g_variant_parse_error_print_context() to format the error message
    from the GVariant parser.
    
    There is a slightly dubious interaction with the "parse me harder"
    functionality here.  We're probably going to have to deal with that
    separately.
