This adds gtk_widget_get/set_opacity, as well as a GtkWidget.opacity
property. Additionally it deprectates gtk_window_get/set_opacity and
removes the GtkWindow.opacity property (in preference for the new
identical inherited property from GtkWidget, which should be ABI/API
compat).
The implementation is using the new gdk_window_set_opacity child
window support for windowed widgets, and cairo_push/pop_group()
bracketing in gtk_widget_draw() for non-window widgets.

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.

The window size can be queried on widget->window directly, no need to
store it in widget->allocation.
This change is necessary because gtk_widget_set_allcation() is now
checking invariants that assume it's called from insize
gtk_widget_size_allocate() and that wasn;t the case here.
GtkWindow always queues a resize on style updates if there is
a grip, because it may have been the grip size style properties
that changed. However, even if it *were*, and it likely wasn't
that would not affect the windows size request, so no need
to queue a resize.
This reverts the size_allocate removal from commit
8449e05865. That code was using
_gtk_window_set_allocation() instead of gtk_widget_set_allocation(). And
that broke glade.
Showing mnemonics immediately on modifier press can be annoying and
distracting when the user is just trying to Alt+Tab into another
application/window since the mnemonic will show up and quickly vanish
again when we receive the focus out event.

Each GtkWindow with an associated GtkApplication should add this as
"app" to its action context. Each GtkApplicationWindow is its own
GActionGroup, and it should add itself to itself with the prefix "win".
There is now some duplication here because we have the new GActionMuxer
hierarchy managed by GtkWidget, but GtkApplicationWindow still carries
its own muxer. The redundancy will be removed in a future patch.
This call was forcing needless work since gtk_window_map() already
does a gdk_window_show() which initially sets GDK_WINDOW_STATE_FOCUSED
that we then handle regularly on the widget's window state event
handler.

gtk_window_get/set_attached_to() is a new API that allows for windows to
be attached to a GtkWidget.
The attachment is a logical binding between the toplevel window and the
widget that generated it; this kind of information is currently used to
propagate style information from the widget to the window, but is also
useful e.g. for accessibility.

'window-unfocused' is too long and mentions "focus" which is historically
loaded with the meaning "input focus".
'backdrop' isn't generally used in GUI speak and still conveys the state the
widgets in an unfocused or background toplevel window are in.
This also removes setting the FOCUSED state flag when
gtk_window_has_toplevel_focus() since this effect can now be done with the new
WINDOW_UNFOCUSED flag instead which actually works better regarding X grabs
and modal windows.
For maximized windows, titlebars cannot be used to reposition or
scale the window, so if an application does not use it to convey
useful information (other than the application name), the screen
space occupied by titlebars could be put to better use.
Add a new window property which requests from the window manager
to hide titlebars when windows are maximized to account for this.

Instead of painting the window background on the grip_window we now
only paint it on the GtkWindow->window, and we make the grip_window
have a transparent background.
We can't really make transparent window handle background optional
via css atm, because the handle color is actually based on the
background color, so if that is set to transparent we won't draw
anything.
gdk_cairo_region_create_from_surface doesn't work correctly on PPC.
This is most prominently seen with the GTK window resize grip, the
shape of which is mirrored every eight pixels horizontally.
At the same time, use an A1 surface for the resize grip shape to
eliminates an A8->A1 surface conversion.
We have an event, so the correct thing to do is to pass
the device into the function that we are calling. GDK
just grew a variant that takes a device, for this purpose.

This commit introduces a new setting, gtk-visible-focus, backed
by the Gtk/VisibleFocus X setting. Its three values control how
focus rectangles are displayed.
'always' is equivalent to the traditional GTK+ behaviour of always
rendering focus rectangles.
'never' does what it says, and is intended for keyboardless
situations, e.g. tablets.
'automatic' hides focus rectangles initially, until the user
interacts with the keyboard, at which point focus rectangles
become visible.
