GtkApplicationWindow frees its internal action group on dispose for the
usual reasons: to avoid the possibility of reference cycles caused by
actions referring back to the window again.
Unfortunately, if it happens to be inside of a GtkActionMuxer at the
time that it is disposed, it will (eventually) be removed from the muxer
after it has been disposed. Removing an action group from a muxer
involves a call to g_action_group_list_actions() which will crash
because the internal action group to which we normally delegate the call
has been freed.
A future patch that reworks the quartz menu code will introduce a use of
GtkActionMuxer in a way that causes exactly this problem.
We can guard against the problem in a number of ways.
First, we can avoid the entire situation by ensuring that we are removed
from the muxer before we destroy the action group. To this end, we
delay destruction of the action group until after the chain-up to the
dispose of GtkWindow (which is where the window is removed from the
GtkApplication).
Secondly, we can add checks to each of our GActionGroup and GActionMap
implementation functions to check that the internal action group is
still alive before we attempt to delegate to it.
We have to be careful, though: because our _list_actions() call will
suddenly be returning an empty list, people watching the group from
outside will have expected to see "action-removed" calls for the
now-missing items. Make sure we send those. but only if someone is
watching.

A widget intended to offer contextual actions for a given view.
It allows packing children into the start or end as well as offering
a single centered child box.

Add gtk_tree_path_new_from_indicesv which takes an array of
integers with a length. Use "Rename to" annotation to rename the
method as gtk_tree_path_new_from_indices. This is needed because
the original method takes variadic arguments which is not supported
by introspection.

GtkMenuItemAccessible was assuming that an accel label is
always the immediate child of a menu item. It also did not
deal with manually set accels. Fix both of these.

Improve the color swatch accessible to set a proper role
depending on whether the swatch is selectable or not, and
set the checked atk state when appropriate.

The initial state of GtkModelMenuItem is that of a normal menu
item, but the accessible we are using, GtkCheckMenuItemAccessible,
starts out with a role of 'check menu item'. Fix that up by
explicitly setting the initial accessible role.
GtkModelMenuItem does not emit the ::toggled signal when a radio
item is activated, so listen for property notification for that
property. We still keep the ::toggled signal handler, in order
to not break other uses of check and radio menu items.
https://bugzilla.gnome.org/show_bug.cgi?id=720983
GtkModelMenuItem emits no property notification, since none of its
properties are readable. But the toggled property is just a proxy
for GtkCheckMenuItem::active, so we should ensure that property
notification is emitted for the ::active property.
Ensure the hscrollbar & vscrollbar at gtk_scrolled_window_add() time,
this allows one to subclass GtkScrolledWindow with templates and add
children, as this will happen at instance initialization time before
the construct adjustment properties take effect.
And update the colorchooser a11y test to a) use GtkColorChooser
instead of the deprecated GtkColorSelection and b) match this
change. Pointed out in

This commit makes the label accessible implement AtkHypertext,
which returns a AtkHyperlink object for each link in the text.
At the same time, add AtkHyperlinkImpl objects as children
to the label accessible.
Also some private API to indicate that links have changed, and
call that from GtkLabel when needed.
Adjust expected output of the affected a11y tests.

The get_end_index implementation was casting the accessible
to AtkText even though GtkLinkButtonAccessible does not
implement this interface. This did not show up in the a11y
tests because the they were not dumping the affected AtkHyperlinkImpl
properties. Oops.
Ignacio Casal Quinteiro reported a problem whereby an empty section at
the start of a menu has a separator placed after it. This was caused by
the implementation of the logic that separators should be inserted at
the top of all non-empty sections that are not the first section. This
logic is obviously incorrect in the case that the first section is empty
(in which case we would not expect to see a separator at the top of the
second section).
Change the logic so that we only insert separators when we see a
non-zero number of actual items in the menu before us.

If the platform data passed with actions and activations includes
a startup notify ID, we should read it and pass it down to GDK.
This ensures that the right startup notify is completed after the
signal emission, and that the user time of the GdkDisplay is properly
updated (which in turn makes sure the windows are not subjected
to focus-stealing-prevention)

This header, which is not universally available, is accidently made to be
included unconditionally during the refactoring of gtkapplication.c,
so restore the #ifdef check.
Applications need a way to fix or adapt the decoration layout,
for situations like split header bars. Setting the layout from
the theme with a style property did not offer a good way to do
this, and the ::show-close-button property does not provide
fine-grained control.
To improve the situation, move the layout string to a property of
GtkHeaderBar which is backed by a setting. This allows platforms to
set a default button layout independent of the theme, while applications
can override the default.
The style GtkWindow style property is now deprecated and ignored.
The button now claims its menu as a child for a11y purposes,
which makes it possible for ATs to see it when the navigate
the tree top-down.
Update the a11y test to match.
