      Refactor GtkApplication · 7fd81cf1

      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.
