iothread: export iothread_stop()
So that internal iothread users can explicitly stop one iothread without
destroying it.
Since at it, fix iothread_stop() to allow it to be called multiple
times. Before this patch we may call iothread_stop() more than once on
single iothread, while that may not be correct since qemu_thread_join()
is not allowed to run twice. From manual of pthread_join():
Joining with a thread that has previously been joined results in
undefined behavior.
