Removed automatic refresh of routes from the route_lookup() function and moved it into an explicit route_refresh() function. The previous behaviour was dangerous, since it meant that even bad routes that someone was looking for were considered fresh. Now such routes time out if they are not explictily refreshed (e.g., on a packet reception)

A new experimental network primitive called an 'announcement'. An
...
announcement is an (ID, value) tuple that is disseminated to local
area neighbors. An application or protocol can explicitly listen to
announcements from neighbors. When an announcement is heard, a
callback is invoked.
Announcements can be used for a variety of network mechanisms such as
neighbor discovery, node-level service discovery, or routing metric
dissemination.
Application programs and protocols register announcements with the
announcement module. An announcement back-end, implemented by the
system, takes care of sending out announcements over the radio, as
well as collecting announcements heard from neighbors.

Inform user about (most likely unintentional) call of dummy_tcpip_output_function.

Added dummy function so that tcpip_output() always is defined, even if tcpip_set_outputfunc() never has been called. This fixes a bug with programs attempting to use the network when compiled for the native platform.

Added logic for announcing that a network has a gateway to the outside world (with the function uip_over_mesh_make_announced_gateway()). The announced gateway sends a trickle message to the network, containing the address of the gateway. Other nodes will then know that packets destined to the outside world should go through the gateway node.

Bugfix: there was a problem with TCP segments not being properly retransmitted for protosockets-based applications. Cleaning up the logic around acknowledgements and retransmissions fixed the bugs pertaining to retransmissions of lost packets. This bugfix affects both the telnet server and the web server (which now work as expected wrt packet loss).
