This allows to specify accelerators in a convenient way, by
adding accel="..." attributes to the menu items in the
XML for the menu.
Currently, the accelerators are extracted only once, when the
menu property is changed on the application.
Move internal accel map API there and update all users.
Also, add an internal function to create an accel path for
an action and parameter, and use it in gtkapplication.c and
gtkmodelmenuitem.c instead of duplicating that code.
This is a GtkWindow subclass that "application windows" will use. Each
is associated with a GtkApplication, has the ability to show menus and
will have its own associated set of actions.
This should be redone to show the label together with the
separator line, somehow. For now, just put the label below
the separator, as a separate item.
Removing the window from the window list before setting the
application to %NULL avoids gtk_application_remove_window() triggering
another call to gtk_application_window_removed(), which would release
the application a second time.

Sub-classes of GtkApplication might want to override the way an
application window is created - for instance, to hook into GtkBuilder
or to set up some basic UI or state.
A new GtkApplication::create_window() virtual function is added to the
GtkApplicationClass vtable, which returns the newly created GtkWindow.
The gtk_application_create_window() function calls the vfunc and adds
the returned window to the list of windows managed by the application
instance.
Calling gtk_application_add_window() will also set the default window,
if one is not already set.
This commit also removes a spurious g_object_ref_sink() on the newly
created GtkWindow.
This is a work in progress to stub out an application class. The
primary goal is to provide a mechanism for applications to export
GtkActions, and there is a standard "Quit" action.
This is based on GApplication.
Future work:
* Add a way to say "This is my application menubar", which gets
put into all toplevel windows on non-OS-X, and into the top
on OS X.
* Support session management.
* Support application settings.
