A button is highlighted if the private variable in_button is TRUE.
This variable is set when the pointer is over the button and cleared when
it left the button. When a button is hidden while there is the pointer over
it, GTK generates a leave notification event, in_button is set to FALSE.
But when a button is removed from a container but not destroyed, it is
unrealized and loose its window. It cannot receive the leave notification
event and in_button stay TRUE. So when the button get a new parent it is still
highlighted.

Touch events don't generate crossing events themselves, so
do not rely on these to determine whether the button release
happened within the event window.
GtkButton currently draws itself as active (pressed down) in case we're
pressing and holding the mouse pointer outside its bounds; this is
misleading though, since we won't activate the button unless the mouse
is released inside the button itself.
Fix this by only setting the ACTIVE state flag when the button is
actually pressed down.

Setting state flags is actually needed here since this function is called by
GtkButton subclasses which add their specific state flags as a parameter.
This reverts commit e868b8d6ea.
This is the interface for GtkWidgets that can be associated with an
action on a GtkAppicationWindow or associated GtkApplication.
It essentially features 'action-name' and 'action-target' properties
with some associated convenience API.
This interface is implemented by GtkButton and GtkToolButton.

Since we allocate the standard CSS border to the button now, and center
the child accordingly, there's no need for an additional inner-border
style property. Deprecate it and ignore its values.

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.

This drops the AtkText implementation, and also strips handling
of children out. Instead of listening for enter/leave/press/released,
just listen for state changes on the widget.
Buttons may also be activated at any time from gtk_widget_activate()
or related functions. In that case, just do the 'show the button
as pushed for a short amount of time' trick, but don't actually
try to grab the keyboard device.

This change does not introduce any functionality change, mostly
cosmtic cleanups, like re-linebreak when introduced annotations messed
up indentation or whitespace errors fixes.
All current users of this CSS property have been updated to deal
with a GtkBorder.
Also a 0 border width has been set in the default CSS to ensure
GtkStyleContext and GtkThemingEngine always provide a non-NULL
pointer for this property.
