Instead of delegating on the parent shell of a menu item/shell on a variety
of situations, Simplify event handling so:
1) Menu item selection is handled entirely on GtkMenuItem through crossing
events.
2) The deepmost menu shell handles clicks inside and outside of it.
This avoids the rather hard to follow gtk_widget_event() calls going on all
throughout the handling of crossing and button events, and makes menus work
again.
It was looping over all items, not breaking out when it found the first
selectable one, and then selecting the _last_ selectable one (if any)
found. So, it did exactly the opposite of its name. This made me quite
baffled when opening a submenu with right-arrow put me at its last item.
Originally, the loop set to_select and broke if the current item was
selectable and not tear-off, meaning that it would correctly select the
first suitable item. However, when tear-off functionality was removed
in commit 4ed9452e90, so was the break.
And with it, gtk_widget_get_visual() and gtk_widget_set_visual() are
gone.
We now always use the RGBA visual (if available) and otherwise fall back
to the system visual.
GtkMenu and GtkMenuBar, the two implementations of GtkMenuShell in GTK,
already draw it.
Furthermore, rendering a background here will overdraw any rendering
that the subclass will do, such as arrows for scrolling menus.
These days exposure happens only on the native windows (generally the
toplevel window) and is propagated down recursively. The expose event
is only useful for backwards compat, and in fact, for double buffered
widgets we totally ignore the event (and non-double buffering breaks
on wayland).
So, by not setting the mask we avoid emitting these events and then
later ignoring them.
We still keep it on eventbox, fixed and layout as these are used
in weird ways that want backwards compat.
Provide a mechanism for hiding the "Quit", "About" and "Preferences"
menu items from the normal places in a traditional menubar layout (in
the File and Edit menus) when the menu is being rendered in the Mac OS
menubar.
These items can already be found in the application menu.
With this feature, applications can now define a single menu to use in
all 'traditional' scenarios.
Use this new attribute in Bloatpad.

Currently we only take into account the window GActionGroup for
activating the accels.
However, the application could have some custom GActionGroup in the
chain of focused widgets that could want to activate some action if
some accel is activated while that widget is focused.
To allow applications to set accels on widgets that use custom
GActionGroups, simply use the muxer of the focused widget, which
already contains the actions of the parents.

We want to make sure that the submenu action is changed back to FALSE
_after_ the menu item has been activated. This prevents the menu
teardown handler from deleting the menu item before it can be activated.
Unfortunately, GtkMenuShell emits "hide" before the item activation.
This is probably done to prevent the application from doing things like
showing dialogs when the menu is still holding the grab.
In the case where we are doing an activate, set a boolean flag on each
of the open menus (following the parent stack) indicating that we'll be
emitting another signal soon (selection done). If that flag is set, we
defer the setting of the submenu action until we receive the second
signal.

GtkMenuTrackerItem::visible was removed a few commits ago.
It is not necessary to bind visible anyway, since the menu
tracker will insert and remove items as their visibility
changes.
Add the possibility of a GtkMenuTracker that performs no section
merging. Instead, it will report an item in the form of a separator for
subsections. It is then possible to get a separate tracker for the
subsection contents by using gtk_menu_tracker_new_for_item_link().
We have some API in GtkMenuTracker and GtkMenuTrackerItem that is
specifically designed to deal with submenus.
Generalise these APIs to take a 'link_name' parameter that we always
give as G_MENU_SUBMENU for now. In the future, this will allow creating
trackers for other types of links, such as sections.
gnome-terminal is still using this setting, so we'll let
applications override it for another cycle. It is no longer
backed by a system-wide setting, though, and it will still
go away eventually.

The window-dragging code had a number of issues: The code was
starting a drag on every button press, never bothering to cancel
them. This leads to the odd hand cursor occurring between the two
clicks to maximize. We relied on GDK's multi-click detection, which
gives us triple-clicks when we really want sequences of double-clicks.
Lastly, we didn't propery restrict double-click handling to the primary
button, so e.g. if you had a window on an empty workspace, double-right
click on the titlebar would maximize it, which is not intended.
This commit solves all three problem by a doing our own double-click
detection, and only starting a drag when the pointer goes out of
'double-click range'. We change the way dragging is implemented for
menubars and toolbars to just letting events bubble up, so they
get the same behaviour as the titlebar. To make this work, we
have to select for pointer motion events in a few more places.
If a menu is opened and it doesn't fit entirely below or above
the menu bar, gtk+ will place it on top. The button release will
then activate the popup item that happens to appear under the
cursor. Avoid this by ignoring release events if they originated
in the parent menu bar and the duration of the press was too short.

When creating separators we were binding the "label" property on the
tracker to the "label" property on the GtkSeparatorMenuItem.
This was problematic for two reasons.
First, it was pointless. The section header label will never change.
Second, it was causing problems: doing the binding caused the value to
be initially synced up, even if it was NULL. Doing this caused
GtkMenuItem to create a GtkAccelLabel and add it as a child, which
prevented the separator from being shown normally.
Change the code a bit so that we just call gtk_menu_item_set_label()
when creating the item, if we find the label to be non-NULL.
Also, show() the separator item at first. GtkMenu manages visibility of
separators internally, but it seems "more correct" to show it ourselves
at first.
In the non-submenu case we bind the 'visibility' attribute to the
tracker, which takes care of showing the item. In the submenu case, we
don't bind all of the properties, so we miss this one.
Deal with it by just show()ing the submenu item.

Add a new class, GtkMenuTrackerItem that represents a menu item, to be
used with GtkMenuTracker.
GtkMenuTracker's insert callback now works in terms of this new type
(instead of passing reference to the model and an index to the item).
GtkMenuShell now handles all of the binding tasks internally, mostly
through the use of property bindings. Having bindings for the label and
visibility attributes, in partiular, will help with supporting upcoming
extensions to GMenuModel.
GtkModelMenu has been reduced to a helper class that has nothing to do
with GMenuModel. It represents something closer to an "ideal" API for
GtkMenuItem if we didn't have compatibility concerns (eg: not emitting
"activate" when setting toggle state, no separate subclasses per menu
item type, supporting icons, etc.) Improvements to GtkMenuItem could
eventually shrink the size of this class or remove the need for it
entirely.
Some GtkActionHelper functionality has been duplicated in
GtkMenuTracker, which is suboptimal. The duplication exists so that
other codebases (such as Unity and gnome-shell) can reuse the
GtkMenuTracker code, whereas GtkActionHelper is very much tied to
GtkWidget. Supporting binding arbitrary GtkWidgets to actions vs.
supporting the full range of GMenuModel features for menu items turns
out to be two overlapping but not entirely similar problems. Some of
the duplication (such as roles) can be removed from GtkActionHelper once
Gtk's internal Mac OS menubar support is ported to GtkMenuTracker.
The intent to reuse the code outside of Gtk is also the reason for the
unusual treatment of the enum type introduced in this comment.
This adds no new "public" API to the Gtk library, other than types that
we cannot make private due to GType limitations.
