RDC phase optimization: correct the behavior in case of memory allocation failure
...
phase_wait did not check whether queuebuf_new_from_packetbuf() returns NULL. This potentially causes send_packet to behave incorrectly; the proper packet would not be sent out (because queuebuf_to_packetbuf(NULL) is a no-op). Instead, whatever has been left in the packet buffer by its previous user will be sent out.

Improved phase lock behaviour when neighbor is not duty cycling: senders notify receivers via the 802.15.4 pending bit that they are not duty cycling. Neighbors then will start sending packets immediately and not wait for neighbors' phase. Tweaking of ContikiMAC timers to make it more reliable.

Two major changes:
...
* Low-power streaming. Experimental support for a low-power mode which
allows rapid exchange of packets with a 16% duty cycle. Does not
seem to function correctly yet though.
* Phase locking. When the phase of a neighbor has been detected, the
sender assumes that the neighbor will keeps it phase and does not
send more strobes than necessary to hit the receiver's channel
check - even if the receiver does not acknowledge the reception of
the strobes when it should have been awake. Instead, the sender
stops strobing and tries again at a later time.
