+ Implement continue/interrupt of thread groups.
+
+ * mi/mi-main.c (proceed_thread_callback): New.
+ (mi_cmd_exec_continue): If --thread-group is specified, resume all
+ threads in that group.
+ (interrupt_thread_callback): New.
+ (mi_cmd_exec_interrupt): If --thread-group is specified, interrupt
+ all threads in that group.
