    libports: fix using ports.h in C++
    
    class is a reserved keyword, event when imported inside extern "C" { }
    
    * libports/ports.h (port_info) [__cplusplus]: Rename `class' field to
    `port_class'.
    (ports_create_port, ports_create_port_noinstall, ports_import_port,
    ports_lookup_port, ports_lookup_payload, ports_count_class,
    ports_enable_class, ports_class_iterate, _ports_bucket_class_iterate,
    ports_inhibit_class_rpcs, ports_resume_class_rpcs): Rename `class'
    parameter to `port_class'.
    [!__cplusplus] (ports_lookup_payload, ports_payload_get_name): Do not
    define extern inlines.
