When GtkApplication starts listening to the screensaver's D-Bus
status, the screensaver-active property is not initialised and
applications making use of the property are out of sync until the
first state change. Any application starting when the screensaver is
active will think it's inactive.
To fix this, we set the property when we first start monitoring the
screensaver.
This is named gdkconstructor.h to avoid any possible conflicts. This fixes
the current usages of G_HAS_CONSTRUCTORS, as that header is not installed
by glib.
A number of applications want to track the state of the screensaver.
Make this information available as a boolean property. We only listen
for state changes when ::register-session is set to TRUE.
This is implemented for unsandboxed D-Bus access by talking
directly to org.gnome.ScreenSaver or org.freedesktop.ScreenSaver,
and for sandboxed D-Bus by using a (new) portal API.
A Quartz implementation is missing.
This function returns global session state that may
not be available to applications (e.g. in sandboxed
environments), and is not needed by applications,
so just drop it, instead of keeping a function around
that can't be guaranteed to work.
When running uninstalled tests with GtkApplication on an autobuilder with
a fake session bus, warnings will cause the tests to abort. The GNOME
session manager, the Xfce session manager, and the Inhibit portal are all
not needed for normal operation of GTK, so we should not log warnings if
they are not found.
As well as not being present on a fake session bus, it's also not
expected that they'll be present on all platforms.

Always return an error if we fail to get a dbus proxy; the callers
are only looking whether error is set, not whether the return value
is NULL.
Use the same function for the inhibit proxy as well, and clean up
the sm_proxy in finalize.
xdg-desktop-portal now has a portal for inhibiting session status
changes. We don't need to use it if we can talk to the session
manager, but if can't, try org.freedesktop.portal.Inhibit.

Xfce4-session-manager added support for managing dbus based clients.
This patch adds support for checking if Xfce session manager is
around after trying the gnome one.

gnome-session takes an "app id" for client and inhibitor registration,
This app id is supposed to be a desktop file id (complete with the
.desktop extension), but gtk+ currently uses g_get_prgname ().
This commit changes gtkapplication to use the application id instead,
which is a much more natural fit. gnome-session is going to be updated
to stop using the .desktop extension, too, so everything is consistent.

Override the gtk-shell-shows-app-menu and gtk-shell-shows-menubar
settings to FALSE, if we can detect that we are not on the same
session bus as the xsettings provider that we got these settings
from.
We determine this by comparing the bus ID of 'our' session
bus with the one reported in the Gtk/SessionBusId xsetting.
If they are different, then it very likely that we are in an ssh
situation where we see the forwarded X display, but not the
session bus. The D-Bus based menu exporting will not work
in this situation.
https://bugzilla.gnome.org/show_bug.cgi?id=671802
Applications can call this to determine if they should an app menu.
This will be %FALSE on desktop environments that do not have an
application menu like the one in gnome-shell. It is %FALSE on Windows
and Mac OS.
Applications are completely free to totally ignore this API -- it is
only provided as a hint to help applications that may be interested in
supporting non-GNOME platforms with a more native 'look and feel'.

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.
