Update gtk3 to version 3.8.2
Rename patch-gtk_a11y_gail.c to patch-gtk_a11y_gtkaccessibility.c

Many improvements, bug fixes and translation updates:
https://git.gnome.org/browse/gtk+/tree/NEWS?id=3.8.2

Highlights:

* Deprecations and removals:
 - Custom CSS properties have been deprecated
 - Support for color schemes has been removed
 - gtk_style_provider_get_style, gtk_style_provider_get_icon_factory
 - GtkGradient and GtkSymbolicColor
 - All the padding style properties in menus

* CSS improvements:
 - Add cycle detection to color resolving

* A lot of filechooser button fixes

* The print dialog now shows printers that are discovered
  using avahi, if configured with --enable-avahi-browsing

* We now support the Window Manager frame synchronization protocol draft (when
  running under a WM that supports it). This means applications will throttle
  their drawing cycle to what the compositor is drawing, and the compositor
  will never render half-updated windows, for seamless resizing and improved
  smoothness in drawing.
  See https://mail.gnome.org/archives/wm-spec-list/2013-January/msg00000.html
  and the articles at http://blog.fishsoup.net/ for more details.

* We now support setting an opacity to any GtkWidget, not just toplevels:
  gtk_window_set_opacity has been deprecated in favor of gtk_widget_set_opacity.

* GtkIconTheme gained asynchronous loaders for GtkIconInfo objects

* GtkIconInfo has changed from being a boxed type to a GObject. This
  is technically an ABI change, but basically all existing code
  will keep working if its used as a boxed type, and its not
  possible to instantiate GtkIconInfos outside Gtk, so this is not
  expected to be a big problem.

* GtkTreeView and GtkIconView allow single-click activation

* GtkImage can be set from a resource

* GdkWaylandDisplay is now public

* gdk_window_set_fullscreen_mode: new function to let windows
  be fullscreened across multiple monitors

* We now use state flags for text direction: GTK_STATE_FLAG_LTR/RTL.
  gtk_style_context_set_direction() has been deprecated.

* We install headers for accessible implementations of GTK+ widgets.
  This makes it possible to implement accessibility for third-party
  widgets by subclassing the proper GTK+ implementation. To do this,
  include gtk/gtk-a11y.h.

* Invisible widgets now return a size of 0x0. This is an experimental
  change that makes GtkWidget::visible essentially behave the same way
  that "display: none" does in CSS. If you want the effect of CSS's
  "visibility: hidden", you can use a GtkNotebook with an empty page.

* GtkFrame now draws a background.

* The Broadway backend now installs a separate server: broadwayd.

* GtkBuilder now lets you refer to external objects from a ui
  file if the objects have been exported with the new function
  gtk_builder_expose_object()

* Font handling has been improved:
 - The default font is no longer handled like a custom style sheet
   that overrides everything, but as the initial value. This is the
   same behavior as in web browsers.
 - It is now possible to set font-family and font-size like other
   CSS properties, and relative font sizes are supported. Font
   sizes in CSS can be specified as numbers or with keywords
   like xx-small, medium, smaller, larger,...

* GTK+ now uses proper Unicode ellipses in strings.
Updated x11/gtk3 to 3.8.2
Update py-gobject3 to 3.8.2

Many bug fixes and improvemnts:
https://git.gnome.org/browse/pygobject/tree/NEWS?id=3.8.2

Highlights:
 - Dot not clobber original Gdk/Gtk functions with overrides
   (Martin Pitt) (#686835)
 - Fix array arguments on 32 bit architectures (Martin Pitt)
 - Add backwards compatible API for GLib.unix_signal_add_full()
   (Martin Pitt)
 - Drop MININT64/MAXUINT64 workaround, current g-i gets this right now
   (Martin Pitt)
 - [API change] Drop almost all static GLib bindings and replace them
   with proper introspection. This gets rid of several cases where the
   PyGObject API was not matching the real GLib API, makes the full GLib
   API available through introspection, and makes the code smaller,
   easier to maintain. For backwards compatibility, overrides are
   provided to emulate the old static binding API, but this will throw a
   PyGIDeprecationWarning for the cases that diverge from the official
   API (in particular, GLib.io_add_watch() and GLib.child_watch_add()
   being called without a priority argument). (Martin Pitt, Simon Feltman)
 - [API change] Deprecate calling GLib API through the GObject
   namespace. This has always been a misnomer with introspection, and
   will be removed in a later version; for now this throws a
   PyGIDeprecationWarning.
 - [API change] Do not bind gobject_get_data() and gobject_set_data().
   These have been deprecated for a cycle, now dropped entirely.
   (Steve Frécinaux) (#641944)
 - [API change] Deprecate void pointer fields as general PyObject
   storage. (Simon Feltman) (#683599)
