Hi,

After I see the comments of this PR and check the code running, I
found that after run_inferior_call call the function, it change the
call_thread->state.
Then set_running will call observer_notify_target_resumed make GDB
output a lot of *running,thread-id="1".
So I make a patch to save call_thread->state and set it back in
run_inferior_call.

Thanks,
Hui
