        This keeps the GUI alive while running an RDI target and lets the
        STOP button be used to stop the target.
        * remote-rdi.c (arm_rdi_stop): New function.  Implements target_stop.
        (init_rdi_ops): Set to_stop target vector entry to the above.
        * rdi-share/ardi.c (stop_request): New variable.  Tells when a stop
        has been requested.
        (angel_RDI_stop_request): New function. Registers that a stop has
        been requested.
        (angel_RDI_ExecuteOrStep): Add call to ui_loop_hook() in loop that
        waits while target is executing.  Initialize and reset stop_request.
        * rdi-share/ardi.h: Add declaration of angel_RDI_stop_request().
