adamdunkels 822149f943 Significant improvements to the Contiki X-MAC:
* the code is simplified, particularly the duty cycling logic
* old unused code has been removed
* Contiki X-MAC now listens before sending a strobe to avoid MAC-level
  collisions
* broadcasts are sent directly, without strobes, reducing the power
  consumption of receivers
* turn off radio for 1 ms between sending a strobe and expecting the
  strobe ack
