Uart communication timer is now bound to rt_timer_read() and no longer to common_ticktime__. Swapping of uart buffers is repositioned, so it is executed just befor/after the actual uart communication. Uart timeout is set according to buffer size: long buffer -> 20ms, short buffer -> 40ms. Decreased max uart devices from 68 to 32.
