/** Application - Core application class.
 * An Application is the foundation of an application, unique for a given
 * application identifier. The Application class wraps some low-level
 * platform-specific services and is intended to act as the foundation for
 * higher-level application classes such as Gtk::Application or MxApplication.
 * In general, you should not use this class outside of a higher level
 * framework.
 *
 * One of the core features that Application provides is process uniqueness,
 * in the context of a "session". The session concept is platform-dependent,
 * but corresponds roughly to a graphical desktop login. When your application
 * is launched again, its arguments are passed through platform communication
 * to the already running program. The already running instance of the program
 * is called the <i>primary instance</i>.
 *
 * Before using Application, you must choose an "application identifier". The
 * expected form of an application identifier is very close to that of of a
 * <a href="
 * http://dbus.freedesktop.org/doc/dbus-specification.html#message-protocol-names-interface">DBus
 * bus name</a>. Examples include: "com.example.MyApp",
 * "org.example.internal-apps.Calculator". For details on valid application
 * identifiers, see id_is_valid().
 *
 * Application provides convenient life cycle management by maintaining a
 * <i>use count</i> for the primary application instance. The use count can be
 * changed using hold() and release(). If it drops to zero, the application
 * exits.
 *
 * Application also implements the ActionGroup interface and lets you easily
 * export actions by adding them with set_action_group(). When
 * invoking an action by calling Gio::ActionGroup::activate_action() on the
 * application, it is always invoked in the primary instance.
 *
 * There is a number of different entry points into an Application:
 *
 * - via 'Activate' (i.e. just starting the application)
 * - via 'Open' (i.e. opening some files)
 * - via activating an action
 *
 * The signal_startup() signal lets you handle the application initialization
 * for all of these in a single place.
 *
 * See the C API docs for an example.

   * to pass <tt>0</tt> if @a argv is not available or commandline handling is not
   * required.
   * 
   * First, the local_command_line() virtual function is invoked.
   * This function always runs on the local instance. It gets passed a pointer
   * to a <tt>0</tt>-terminated copy of @a argv and is expected to remove the arguments
   * that it handled (shifting up remaining arguments). See
   * <xref linkend="gapplication-example-cmdline2"/> for an example of
   * parsing @a argv manually. Alternatively, you may use the OptionContext API,
   * after setting <tt>argc = g_strv_length (argv);</tt>.
   * 
   * The last argument to local_command_line() is a pointer to the @a status
   * variable which can used to set the exit status that is returned from
   * g_application_run().
   * 
   * If local_command_line() returns <tt>true</tt>, the command line is expected
   * to be completely handled, including possibly registering as the primary
   * instance, calling g_application_activate() or g_application_open(), etc.
   * 
   * If local_command_line() returns <tt>false</tt> then the application is registered
   * and the Application::signal_command_line() signal is emitted in the primary
   * instance (which may or may not be this instance). The signal handler
   * gets passed a ApplicationCommandLine object that (among other things)
   * contains the remaining commandline arguments that have not been handled
   * by local_command_line().
   * 
   * If the application has the APPLICATION_HANDLES_COMMAND_LINE
   * flag set then the default implementation of local_command_line()
   * always returns <tt>false</tt> immediately, resulting in the commandline
   * always being handled in the primary instance.
   * 
   * Otherwise, the default implementation of local_command_line() tries
   * to do a couple of things that are probably reasonable for most
   * applications.  First, g_application_register() is called to attempt
   * to register the application.  If that works, then the command line
   * arguments are inspected.  If no commandline arguments are given, then
   * g_application_activate() is called.  If commandline arguments are
   * given and the APPLICATION_HANDLES_OPEN flag is set then they
   * are assumed to be filenames and g_application_open() is called.
   * 
   * If you need to handle commandline arguments that are not filenames,
   * and you don't mind commandline handling to happen in the primary
   * instance, you should set APPLICATION_HANDLES_COMMAND_LINE and
   * process the commandline arguments in your Application::signal_command_line()
   * signal handler, either manually or using the OptionContext API.
   * 
   * If you are interested in doing more complicated local handling of the
   * commandline then you should implement your own Application subclass
   * and override local_command_line(). In this case, you most likely want
   * to return <tt>true</tt> from your local_command_line() implementation to
   * suppress the default handling. See
   * <xref linkend="gapplication-example-cmdline2"/> for an example.
   * 
   * If, after the above is done, the use count of the application is zero
   * then the exit status is returned immediately.  If the use count is
   * non-zero then the default main context is iterated until the use count
   * falls to zero, at which point 0 is returned.
   * 
   * If the APPLICATION_IS_SERVICE flag is set, then the service will
   * run for as much as 10 seconds with a use count of zero while waiting
   * for the message that caused the activation to arrive.  After that,
   * if the use count falls to zero the application will exit immediately,
   * except in the case that g_application_set_inactivity_timeout() is in
   * use.
   * 
   * This function sets the prgname (Glib::set_prgname()), if not already set,
   * to the basename of argv[0].  Since 2.38, if APPLICATION_IS_SERVICE
   * is specified, the prgname is set to the application ID.  The main
