/** 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.

   * Application::signal_handle_local_options() signal will be emitted.  At this
   * point, the application can inspect the values pointed to by @a arg_data
   * in the given OptionEntrys.
   * 
   * Unlike OptionContext, Application supports giving a <tt>0</tt>
   *  @a arg_data for a non-callback OptionEntry.  This results in the
   * argument in question being packed into a VariantDict which is also
   * passed to Application::signal_handle_local_options(), where it can be
   * inspected and modified.  If APPLICATION_HANDLES_COMMAND_LINE is
   * set, then the resulting dictionary is sent to the primary instance,
   * where g_application_command_line_get_options_dict() will return it.
   * This "packing" is done according to the type of the argument --
   * booleans for normal flags, strings for strings, bytestrings for
   * filenames, etc.  The packing only occurs if the flag is given (ie: we
   * do not pack a "false" Variant in the case that a flag is missing).
   * 
   * In general, it is recommended that all commandline arguments are
   * parsed locally.  The options dictionary should then be used to
   * transmit the result of the parsing to the primary instance, where
   * Glib::variant_dict_lookup() can be used.  For local options, it is
   * possible to either use @a arg_data in the usual way, or to consult (and
   * potentially remove) the option from the options dictionary.
   * 
   * This function is new in GLib 2.40.  Before then, the only real choice
   * was to send all of the commandline arguments (options and all) to the
   * primary instance for handling.  Application ignored them completely
   * on the local side.  Calling this function "opts in" to the new
   * behaviour, and in particular, means that unrecognised options will be
   * treated as errors.  Unrecognised options have never been ignored when
   * APPLICATION_HANDLES_COMMAND_LINE is unset.
   * 
   * If Application::signal_handle_local_options() needs to see the list of
   * filenames, then the use of OPTION_REMAINING is recommended.  If
   *  @a arg_data is <tt>0</tt> then OPTION_REMAINING can be used as a key into
   * the options dictionary.  If you do use OPTION_REMAINING then you
   * need to handle these arguments for yourself because once they are
   * consumed, they will no longer be visible to the default handling
   * (which treats them as filenames to be opened).

   * application can inspect the values of its OptionEntrys.
   * 
   * Application::signal_handle_local_options() is a good place to handle options
   * such as `--version`, where an immediate reply from the local process is
   * desired (instead of communicating with an already-running instance).
   * A Application::signal_handle_local_options() handler can stop further processing
   * by returning a non-negative value, which then becomes the exit status of
   * the process.
   * 
   * What happens next depends on the flags: if
   * APPLICATION_HANDLES_COMMAND_LINE was specified then the remaining
   * commandline arguments are sent to the primary instance, where a
   * Application::signal_command_line() signal is emitted.  Otherwise, the
   * remaining commandline arguments are assumed to be a list of files.
   * If there are no files listed, the application is activated via the
   * Application::signal_activate() signal.  If there are one or more files, and
   * APPLICATION_HANDLES_OPEN was specified then the files are opened
   * via the Application::signal_open() signal.
   * 
   * 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
   * [gapplication-example-cmdline2.c][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
   * impact of this is is that the wmclass of windows created by Gtk+ will
   * be set accordingly, which helps the window manager determine which
   * application is showing the window.
   * 
   * Since 2.40, applications that are not explicitly flagged as services
   * or launchers (ie: neither APPLICATION_IS_SERVICE or
   * APPLICATION_IS_LAUNCHER are given as flags) will check (from the
   * default handler for local_command_line) if "--gapplication-service"
   * was given in the command line.  If this flag is present then normal
   * commandline processing is interrupted and the
   * APPLICATION_IS_SERVICE flag is set.  This provides a "compromise"
   * solution whereby running an application directly from the commandline
   * will invoke it in the normal way (which can be useful for debugging)
   * while still allowing applications to be D-Bus activated in service
   * mode.  The D-Bus service file should invoke the executable with
   * "--gapplication-service" as the sole commandline argument.  This
   * approach is suitable for use by most graphical applications but
   * should not be used from applications like editors that need precise
   * control over when processes invoked via the commandline will exit and
   * what their exit status will be.
