Implemented ring_buffer iterators.
* runtime/transport/ring_buffer.c (_stp_ring_buffer_empty_cpu): New function.
(_stp_ring_buffer_empty): Ditto.
(_stp_ring_buffer_iterator_increment): Ditto.
(_stp_tracing_wait_pipe): Calls _stp_ring_buffer_empty() instead of
ring_buffer_empty().
(_stp_peek_next_event): Looks at iterators first.
(_stp_find_next_event): Calls _stp_ring_buffer_empty_cpu() and
increments iterator.
(_stp_data_read_trace): Opens and closes ring_buffer iterators.
(_stp_data_poll_trace): Calls _stp_ring_buffer_empty().
(__stp_relay_wakeup_timer): Ditto.
* runtime/transport/control.c (_stp_ctl_write_cmd): Increased level
required to get a debug print.
