Submenus are not actually attached to a menubar, but styling them
as if they were imposes some problems (at least with Adwaita).
Just using GDK_WINDOW_TYPE_HINT_POPUP_MENU for submenus instead
fixes the issue.

And the getter, too: gtk_menu_item_get_right_justified() and the
corresponding property. Also make the only caller use the private
structure (as it did before the recent patches).
Copy over the implementation of _gtk_menu_shell_activate
so that C4013 warning/error (aka gcc's "implicit
declaration of ...") can be avoided when compiling with MSVC
This is in response of the changes for bug 554057 in commit

This is needed by GtkTreeMenu to ensure that child menu items
reserve space for the submenu indicator even if they dont have
submenus... in this way we ensure the same size of all cell
areas in the menu items at allocation/request time.
The show_submenu_indicator flag was explicitly set in various
places from GtkMenu/GtkMenuBar at request times, since the
GtkMenuItem already checks the parent type for GTK_IS_MENU_BAR()
in various places, removed this flag in favor of just checking
the parent type (only in the interest of better readable code).
It doesn't make sense to keep them separate as GtkSizeRequest requires a
GtkWidget and GtkWidget implements GtkSizeRequest, so you can never have
one without the other.
It also makes the code a lot easier because no casts are required when
calling functions.
Also, the names would translate to gtk_widget_get_width() and people
agreed that this would be a too generic name, so a "preferred" was added
to the names.
So this patch moves the functions:
gtk_size_request_get_request_mode() => gtk_widget_get_request_mode()
gtk_size_request_get_width() => gtk_widget_get_preferred_width()
gtk_size_request_get_height() => gtk_widget_get_preferred_height()
gtk_size_request_get_size() => gtk_widget_get_preferred_size()
gtk_size_request_get_width_for_height() =>
gtk_widget_get_preferred_width_for_height()
gtk_size_request_get_height_for_width() =>
gtk_widget_get_preferred_height_for_width()
... and moves the corresponding vfuncs to the GtkWidgetClass.
The patch also renames the implementations of the vfuncs in widgets to
include the word "preferrred".
With the demise of GtkList and GtkTree, it has GtkMenuItem as sole
derived class, and is not really adding any value as a separate class.
Its few useful features have been merged into GtkMenuItem.
Bug 629104
The GtkSubmenuDirection and GtkSubmenuPlacement enumerations
have been deprecated as public API for a while, but are still used
internally in the menu code. Move them to a private header. This
also prevents to generation of GObject boilerplate for these enums.
