This header, which is not universally available, is accidently made to be
included unconditionally during the refactoring of gtkapplication.c,
so restore the #ifdef check.
gtkapplication.c has turned into a bit of an #ifdef mess over time, and
many of the current checks are incorrect. As an example, if you build
Gtk for wayland, and exclude the X11 backend, much of the functionality
required by wayland (such as exporting menu models) will be disabled.
Solve that by introducing a backend mechanism to GtkApplication (named
GtkApplicationImpl) similar to the one in GApplication. Add backends
for Wayland, X11 and Quartz, with X11 and Wayland sharing a common
'DBus' superclass.

GtkApplicationImpl itself is essentially a bunch of vfuncs that serve as
hooks for various things that the platform-specific backends may be
interested in doing (startup, shutdown, managing windows, inhibit, etc.)
With this change, all platform specific code has been removed from
gtkapplication.c and gtkapplicationwindow.c (both of which are now free
of #ifdefs, except for a UNIX-specific use of GDesktopAppInfo in
gtkapplicationwindow.c).
Additionally, because of the movement of the property-setting code out
of GtkApplicationWindow, the _GTK_APPLICATION_ID properties (and
friends) will be set on non-GtkApplicationWindows, such as dialogs.

Rework how accels are handled on GtkApplicationWindow.
Instead of having GtkApplication fill the GtkAccelMap which is then used
by GtkApplicationWindow to create a GtkAccelGroup filled with closures
that is then associated with the window, do it directly.
GtkApplication now keeps a list of accels and their actions.
Accelerators on a GtkApplicationWindow ask GtkApplication to execute the
appropriate action.
This saves a fair bit of complexity and memory use (due to not having to
create all those closures and accelmap entries). The new approach also
supports multiple accels per action (although there is not yet a public
API for it).
This patch (and the ones before) Reviewed and ACK'd by Matthias Clasen.
Previously, GtkWindow would add the "app" action group to its own
toplevel muxer.
Change the setup so that GtkApplication creates the toplevel muxer and
adds itself to it as "app". Use this muxer as the parent muxer of any
GtkWindow associated with the application.
This saves a small amount of memory and will allow for accels to be
propagated from the application through to all of the windows.
Applications have no way of finding out if a session manager proxy was
successfully created in gtk_application_startup_session_dbus(), so it's not
appropriate for certain public GtkApplication functions to be asserting the
presence of a session manager proxy as if it were a programmer error.
This affects:
gtk_application_inhibit()
gtk_application_is_inhibited()
If sm_proxy is NULL, the function should just return silently.
In the case of gtk_application_uninhibit(), the application should only be
calling this if it obtained a valid cookie, which implies the presence of a
session manager proxy. I noted that with a comment.

This is fallout from commit 257b42e2f9 -
those fields were already getting freed in
gtk_application_shutdown_x11() and my commit caused crashes on quit
instead.
Thanks to Rico Tzschichholz for reporting the bug and testing this fix.
Makes name consistent with other quartz-only modules and makes it clear that this works with the GMenuModel system rather than the older GtkMenu system.
GApplication now makes the session bus and object path available as a
public API on the application instance. Use that instead of trying to
guess values for ourselves.
This causes this version of Gtk+ to depend on GLib 2.32.2, so bumping
version dependency accordingly.

We currently have a couple of cases where GtkApplication assumes that
the session bus will be non-NULL causing critical error output or (in
the case of trying to publish menus) an infinite loop.
Three fixes:
- if the session bus is NULL due to not having registered the
GtkApplication yet then give a g_critical on the entry point to the
menu setters instead of going into an infinite loop. Document this.
- check for NULL session bus even when calling the menu setters at the
right time in order to prevent the infinite loop for
non-programer-error cases (ie: because we had trouble connecting to
the session bus)
- check for NULL session bus when publishing the X11 properties on the
GtkApplicationWindow and skip publishing them if we're not on the bus

gtk_application_set_app_menu(), gtk_application_set_menubar():
Mention that you probably want to call this in the startup signal
handler. If you do it earlier you will likely get a warning about
a missing D-Bus connection, because doing it earlier does not
make sense anyway.
Instead of firing a 'quit' signal and expecting the application to do
something that will cause it to quit, just call the new
g_application_quit() API for ourselves.

This seems a bit "too powerful" and unlikely to be used by most
applications. Remove it from now, until someone comes up with a strong
desire for it.
