Rework how accels are handled on GtkApplicationWindow.
Instead of having GtkApplication fill the GtkAccelMap which is then used
by GtkApplicationWindow to create a GtkAccelGroup filled with closures
that is then associated with the window, do it directly.
GtkApplication now keeps a list of accels and their actions.
Accelerators on a GtkApplicationWindow ask GtkApplication to execute the
appropriate action.
This saves a fair bit of complexity and memory use (due to not having to
create all those closures and accelmap entries). The new approach also
supports multiple accels per action (although there is not yet a public
API for it).
This patch (and the ones before) Reviewed and ACK'd by Matthias Clasen.
Previously, GtkWindow would add the "app" action group to its own
toplevel muxer.
Change the setup so that GtkApplication creates the toplevel muxer and
adds itself to it as "app". Use this muxer as the parent muxer of any
GtkWindow associated with the application.
This saves a small amount of memory and will allow for accels to be
propagated from the application through to all of the windows.
Resize modes don't work anymore, both because nobody ever uses them and
because the frame clock changed the way things work quite a bit. So we
don't want to advertise them as a good idea.

Previously, we were showing and hiding the custom titlebar
widget in response to state changes such as maximization.
Instead, use gtk_widget_set_child_visible() and leave
show/hide to applications. This makes it possible to set
a custom titlebar and hide it, for a titlebar-less appearance.

The size of the shadow and invisible borders can (and usually
will) change between backdrop and focused windows, while the
overall window size remains unchanged. This causes the visible
window to visually 'jump'. We can avoid this by always reserving
the maximum of the focused and unfocused border sizes. The code
for positioning the input-only windows making up the invisible
border is adjusted to deal with this. We now always place the
invisible border right outside the visible content, even if the
shadow extends out much farther.

We need to subtract border_width from the size we're passing to the
children hfw functions as those are added by ourselves.
Fixes the window-border-width.ui reftest.
At least for header bars, there's often application controls
in this area, which should be included in the focus chain.
We make it so that the initial focus avoids the titlebar,
but tabbing around will eventually get there.

There were some code added to this file that is meant for the X11 backend,
but they are being unconditionally built. Add build-time checks for the
X11 backend for these to fix the build on non-X11 platforms.
We'll use a style class to be able to give this a different appearance,
but for the time being we don't really need to give this such different
margin.

"title_box" is used for both a custom header bar and for a titlebar.
Since we want to help differentiate these cases in the code, rename
everything titlebar-internal to use "titlebar_".

Attached widgets inherit from the style of the widget they are
attached to. This can sometimes have unintended consequences,
like a context menu in the main view of gedit inheriting the font
that is configured for documents, or the context menu of the preview
in the font chooser coming up with humongous font size.
To fix this problem, we introduce a context menu style class
and use it for all menus that are used like that. The theme
can then set a font for this style class.

Make sure we always deal with the same screen when
connecting / disconnecting the theme-variant changed handler.

We've recently a number of classes wholly. For these cases,
move the headers and sources to gtk/deprecated/ and adjust
Makefiles and includes accordingly.
Affected classes:
GtkAction
GtkActionGroup
GtkActivatable
GtkIconFactory
GtkImageMenuItem
GtkRadioAction
GtkRecentAction
GtkStock
GtkToggleAction
GtkUIManager
Other code assumes that the widget has a window if it is realized.
Since we might trigger such code indirectly from gtk_window_realize,
don't mark the window as realized before we've registered its window.
