There were many bugs in the rtimer code, particularly one that made only one rtimer at a time work. We have a new rtimer system that we're testing, but in the meantime, I rewrote the rtimer code to explicitly support only one rtimer. Makes the code significantly simpler (and fixes a bug that was very hard to track down).

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

A simple addition with significant performance implications:
...
sicslowpan tags TCP packets with the PACKETBUF_ATTR_PACKET_TYPE_STREAM
flag, which makes the underlying power-saving MAC layer keep the radio
on for some time after transmitting the packet. This allows reply
packets to be processed directly, significantly increasing TCP latency
and throughput.

A new optimization to X-MAC: senders now keep track of when neighbors

last were known to be awake. When sending a packet, a sender does not

reduces power consumption for senders and decreases the contention in
the network as there are less packets in the air. Additionally, the
ACK optimization was improved so that data/ack exchanges now are
more efficient.
