Reverted the recent change from random_rand() to rand(). It turned out that
...
since libc rand() returns a signed int, there were frequently problems with
timer values wrapping. By reverting to random_rand(), we can provide a
random generator that returns an unsigned and the timer problems are solved.

Reduced the size of the packet cache from four to two to avoid falseley dismissing fresh packets (the header field that hold sequence numbers is only two bits wide, hence all sequence numbers fits in a four-entry cache...)

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.

Neighbor ETX should accumulate over retransmission timeouts;
...
Best neighbor has minimum sum of routing metric and neighbor ETX. Previously best neighbor prioritizes routing metric before neighbor ETX, which often causes a poor neighbor with a good upstream path to be selected.
