[gtk/readonly-events-1: 39/51] New focus change handling



commit fdee5482bb6434fab80fa72b8e467d98fbf5ab01
Author: Matthias Clasen <mclasen redhat com>
Date:   Wed Feb 12 20:26:29 2020 -0500

    New focus change handling
    
    Instead of relying on gdk's antiquated crossing events,
    create a new GtkCrossingData struct that contains the
    actual widgets, and a new event controller vfunc that
    expects this struct. This also saves us from making sense
    of X's crossing modes and details, and makes for a
    generally simpler api.
    
    The ::focus-in and ::focus-out signals of GtkEventControllerKey
    have been replaced by a single ::focus-change signal that
    takes GtkCrossingData as an argument. All callers have
    been updated.
