radio connection update: radio should not be removed from destinations, but instead flagged as interfered.
...
(and the radio medium will keep delivering data also to interfered destinations to avoid the half-filled RXFIFO problem)

radio medium update: receiving nodes that become interfered still receive connection data, but may (should) choose to ignore or corrupt it.
...
this solves a problem with half-filled FIFO buffers on CC2420 radio platforms
+ minor fixes: the received signal strength is the maximum of all active connection, and a transmitting radio may still be interfered

ab01f2b901
added new radio medium: directed graph radio medium (short: dgrm).
...
this radio medium will likely later be used to implement other more complex radio mediums such as udgm and mrm.
currently the user interface (dgrm config plugin) for defining radio links is very limited.
experimental: the new radio medium supports propagation delays, configurable via the plugin.

e87d94439e
added experimental per destination propagation delay in radio connections. uses cooja time events to delay radio events.
...
currently only delaying the four main events: reception started, packet delivery, byte delivery, and reception ended
note that propagation delay is not yet implemented for all radio events - interfered radios will for example still be interfered immediately
