Updated Contiki X-MAC to use hardware acks, which allows for tighter timing and results in a lower duty cycle. Hardware acks also make X-MAC more robust against packet losses, as there is a direct way for the CSMA layer to detect loss of data packets. Before, Contiki X-MAC only detected loss of strobes.

Rework of the CSMA layer: instead of using one timer per packet, the module now uses one central timer and a queue of outgoing packets. This helps to keep packets in order, which is extremely useful for TCP transfers, and reduces the amount of congestion since consecutive packets now are spaced in time if there is a collision. Based on the observations and ideas of Simon Duquennoy.
