Since you can't take grabs on unmapped windows, GtkMenu takes a grab on
the menu in a convoluted way: it first grabs another window, shows the
menu window, and then transfers the grab over to the GtkMenu widget.
For normal menubars, this is perfectly fine, as the first window it grabs
is our toplevel, and that gets picked up in our transient path. For
GtkMenuButton or other spurious uses of gtk_menu_popup, it creates a new
temporary input-only window which it takes the grab on, known as the "grab
transfer window". Since this window isn't a transient-for of our new menu
widget window, the grab isn't noticed when we go to show it, and thus the
menu ends up as a new toplevel.
Add a special hack to GtkMenu and the Wayland backend which lets us notice
this "grab transfer window", and include it in our grab finding path.
It's sort of terrible to have to hack up the widgets instead of just the
backend, but the alternative would be an entirely new window type which is
managed correctly by GDK. I don't want to write that.
GtkMenu calls gtk_widget_size_allocate on its GtkWindow during
gtk_menu_popup_for_device if the menu has not been realised. This can cause the
allocation of the GtkWindow and the size of the GdkWindow to become out of sync
because a top level GtkWindow does not attempt to re-size the GdkWindow when
its allocation is set.

This replaces the previously hardcoded calls to gdk_window_set_user_data,
and also lets us track which windows are a part of a widget. Old code
should continue working as is, but new features that require the
windows may not work perfectly.
We need this for the transparent widget support to work, as we need
to specially mark the windows of child widgets.

Make the main (and only) entry-point to gtkmodelmenu.c the now-public
gtk_menu_shell_bind_model().
Move the convenience constructors (gtk_menu_new_from_model() and
gtk_menu_bar_new_from_model()) to their proper files.
Remove the private header file.
Simplify the code a bit by making the initial populate part of the
bind() call.

This allows adding a GActionGroup with a given name at an arbitrary
point in the widget tree.
This patch also adds an internal _get_action_muxer() API. Calling this
will create a GActionMuxer associated with the widget. The parent of
the muxer will be the muxer of the widget's conceptual parent. For
non-menus, that is the normal parent. For menus, it is the attach
widget.
In this way, we end up with a hierarchy of GActionMuxer that largely
reflects the hierarchy of GtkWidget, but only in places that the action
context has been requested. These muxers are the ones on which the
inserted actions groups are installed.
A following patch will add a user of this API.
Specially in the case of comboboxes, those menus could enable scrolling
even if the contents could fit in the work area, and could show blank
space in order to line up the selected item with the combobox.
When such thing happens, take into account scroll_offset when relocating
the menu contents so contents don't jump directly onscreen, and apply
it so scrolling is allowed in the direction that brings the menu onscreen
and blocked in the opposite direction.
Also, wait for cancelling the scroll operation until the touch is released
even if the scrolling arrows disappeared, so the menu item underneath isn't
selected right away.

When the menu is detached, the attach-widget property changes value to
NULL, so we should notify a property change, like
gtk_menu_attach_to_widget() does.

This was broken since before GTK+ 3.0, when we replaced
a use of requisition by allocation. Fix this by using the
requisition height, that is already cached by the menu code.
The math is not quite right here; if you page all the way
down a long menu, you end up on the second-to-last menuitem.
But at least, page up/down let you move up and down the menu
again.

Add an internal API that allows GtkStyleContext to create a widget path
for the widget and with that bypassing gtk_widget_get_path() and that
function caching the path.
