Move all the functions in ui.c to be members of a ScreenRecoveryUI class, which is a subclass of an abstract RecoveryUI class. Recovery then creates a global singleton instance of this class and then invoke the methods to drive the UI. We use this to allow substitution of a different RecoveryUI implementation for devices with radically different form factors (eg, that don't have a screen).
