From Grant Edwards <grante@visi.com>
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().
