[gtk+/touchscreens: 17/67] entry: Handle ::grab-notify

[Carlos Garnacho <carlosg src gnome org>]

commit bbe21bd47fc762da88e1a78cb8b9b25b484eb3f2

    entry: Handle ::grab-notify
    
    Store the device, and unset private fields whenever the device
    is shadowed by another GTK+ grab, so popping up menus while
    selecting (i.e. press-and-hold) doesn't leave it in a confused
    state.
