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.

Bugfixes in low-power streaming mode, and re-added support for announcements. These now use the low-power streaming mode so that active listening for announcments have a radio duty cycle of 16% rather than 100%

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.
