Default behaviour should be unchanged.

Added the low-power streaming mode where frequent channel checks are performed when streaming is on. Enabling this will (by setting WITH_STREAMING to 1), however, significantly slow down Cooja/MSPsim simulations.

Let ContikiMAC remember the state that the radio should have when duty cycling is turned off. This fixes a bug in which the radio was turned on after sending, even when NETSTACK_RDC.off(0) was enabled.

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.
