Emmanuele Bassi 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

/**
* SECTION:gtkentry
* @Short_description: A single line text entry field
* @Title: GtkEntry
* @See_also: #GtkTextView, #GtkEntryCompletion
*
* The #GtkEntry widget is a single line text entry
* widget. A fairly large set of key bindings are supported
* by default. If the entered text is longer than the allocation
* of the widget, the widget will scroll so that the cursor
* position is visible.
*
* When using an entry for passwords and other sensitive information,
* it can be put into “password mode” using gtk_entry_set_visibility().
* In this mode, entered text is displayed using a “invisible” character.
* By default, GTK+ picks the best invisible character that is available
* in the current font, but it can be changed with
* gtk_entry_set_invisible_char().
*
* GtkEntry has the ability to display progress or activity
* information behind the text. To make an entry display such information,
* use gtk_entry_set_progress_fraction() or gtk_entry_set_progress_pulse_step().
*
* Additionally, GtkEntry can show icons at either side of the entry. These
* icons can be activatable by clicking, can be set up as drag source and
* can have tooltips. To add an icon, use gtk_entry_set_icon_from_gicon() or
* one of the various other functions that set an icon from an icon name or a
* paintable. To trigger an action when the user clicks an icon,
* connect to the #GtkEntry::icon-press signal. To allow DND operations
* from an icon, use gtk_entry_set_icon_drag_source(). To set a tooltip on
* an icon, use gtk_entry_set_icon_tooltip_text() or the corresponding function
* for markup.
*
* Note that functionality or information that is only available by clicking
* on an icon in an entry may not be accessible at all to users which are not
* able to use a mouse or other pointing device. It is therefore recommended
* that any such functionality should also be available by other means, e.g.
* via the context menu of the entry.
*
* # CSS nodes
*
* |[<!-- language="plain" -->
* entry[.flat][.warning][.error]
* ├── text[.readonly]
* ├── image.left
* ├── image.right
* ╰── [progress[.pulse]]
* ]|
*
* GtkEntry has a main node with the name entry. Depending on the properties
* of the entry, the style classes .read-only and .flat may appear. The style
* classes .warning and .error may also be used with entries.
*
* When the entry shows icons, it adds subnodes with the name image and the
* style class .left or .right, depending on where the icon appears.
*
* When the entry shows progress, it adds a subnode with the name progress.
* The node has the style class .pulse when the shown progress is pulsing.
*
* For all the subnodes added to the text node in various situations,
* see #GtkText.
*
* # GtkEntry as GtkBuildable
*
* The GtkEntry implementation of the GtkBuildable interface supports a
* custom <attributes> element, which supports any number of <attribute>
* elements. The <attribute> element has attributes named “name“, “value“,
* “start“ and “end“ and allows you to specify #PangoAttribute values for
* this label.
*
* An example of a UI definition fragment specifying Pango attributes:
* |[
* <object class="GtkEnry">
* <attributes>
* <attribute name="weight" value="PANGO_WEIGHT_BOLD"/>
* <attribute name="background" value="red" start="5" end="10"/>
* </attributes>
* </object>
* ]|
*
* The start and end attributes specify the range of characters to which the
* Pango attribute applies. If start and end are not specified, the attribute is
* applied to the whole text. Note that specifying ranges does not make much
* sense with translatable attributes. Use markup embedded in the translatable
* content instead.
