We want the menu realized so we know the size it's allocating to itself.
And we need that size to position the menu properly.
This is best visible on right-to-left.
Lots of code calls gtk_menu_popup() and we don't want to resize the
window needlessly.
In this particular case, keyboard navigation to submenus caused those
submenus to shrink.
Note: I'm not sure this fix doesn't have nasty side effects, as I'm not
a specialist on menu popup code, so if it does, we'll need to revert it.
Until then, let's keep it, it fixes a bug.
This change does not introduce any functionality change, mostly
cosmtic cleanups, like re-linebreak when introduced annotations messed
up indentation or whitespace errors fixes.
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).
All current users of this CSS property have been updated to deal
with a GtkBorder.
Also a 0 border width has been set in the default CSS to ensure
GtkStyleContext and GtkThemingEngine always provide a non-NULL
pointer for this property.
Some GtkSettings property are registered by other classes. This leads
to the "interesting" issue that setting GtkSettings:gtk-button-images
requires that the GtkButton class is referenced first - or that a
GtkButton is created.

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".
