Xbee 802.15.4 modem driver for Arduino

This radio driver allows to use an XBee 802.15.4 modem with an Arduino board, using the official Arduino Wireless/SD shield (see http://arduino.cc/en/Main/ArduinoWirelessShield) for connection.

We don't use a C++ compiler to compile C files. Probably most of RIOT would be broken if you compile it with G++, because of some subtle differences between C and C++.
