uart0 functionality is removed by #3164. This patch implements periph/uart, rather than deprecated uart0, using /dev/tty. To use with netdev2_tap simultaneously, this patch adds asynchronus read system and modifies netdev2_tap to use it. A TTY device is specified on command line with -c (COM) option, since -t was used by the old implementation. This patch also implements empty GPIO driver needed by the xbee driver.
