9a943e21d3 stack: Update HIDDEN a11y state for stack pages
This will let us handle additions and removals
in the AT-SPI backend.

434b145ee0 stack: Don't transition when the visible child is remove
This is a corner-case, and it is causing crashes in
the shortcuts window, after a11ab6c995.

1d802881eb stack: Change ordering for removal
Unparent the child widget before tearing down its
stack page. This is necessary so a11y can still access
the stack page accessible to emit change notification
when it learns that the child is removed.

7c6c718e19 stack: Turn pages into accessibles
This requires some cleanup to remove assumptions
about accessibles being widgets in the backend,
and some code to navigate the tree with these
extra objects in between widgets.

The accessibles for stack pages have the role
GTK_ACCESSIBLE_ROLE_TAB_PANEL. This is the first
step towards implementing the tabs patterns
as described in the aria authoring guidelines
for GtkStack.

cc9fe4b354 stack: Add gtk_stack_add_child
The name of children is not essential, so add
a way to add children without providing one.

c63087a563 Remove ATK
To build a better world sometimes means having to tear the old one down.
        -- Alexander Pierce, "Captain America: The Winter Soldier"

ATK served us well for nearly 20 years, but the world has changed, and
GTK has changed with it. Now ATK is mostly a hindrance towards improving
the accessibility stack:

 - it maps to a very specific implementation, AT-SPI, which is Linux and
   Unix specific
 - it requires implementing the same functionality in three different
   layers of the stack: AT-SPI, ATK, and GTK
 - only GTK uses it; every other Linux and Unix toolkit and application
   talks to AT-SPI directly, including assistive technologies

Sadly, we cannot incrementally port GTK to a new accessibility stack;
since ATK insulates us entirely from the underlying implementation, we
cannot replace it piecemeal. Instead, we're going to remove everything
and then incrementally build on a clean slate:

 - add an "accessible" interface, implemented by GTK objects directly,
   which describe the accessible role and state changes for every UI
   element
 - add an "assistive technology context" to proxy a native accessibility
   API, and assign it to every widget
 - implement the AT context depending on the platform

The stack wasn't updating its visible-child when
the stack pages visible property changes. This
showed up in the inspector, when showing the details

3bd648e72e stack: stop keeping a cached child render node around
All widgets cache their render node already. Just allocate the
last_visible_child always at 0/0 and then move its rendernode around
during snapshot.

b55195fa2e Move the idle sizer to GtkWindow
This was only living in gtkcontainer.c for historic
reasons. Move it closer to where it belongs, and
rename it from 'idle' to 'layout', since it is
really about the layout phase of the frame clock,
nowadays.
