Rewrite of the congestion logic. A node now report it being congested
...
when half the transmission queue is full. When a neighbor is heard to
be congested, the rtmetric of that node is inflated to avoid sending
more traffic in its direction.
Fixed problems with beacon intervals: intervals are now not reduced
when a path gets significantly worse, only when they get better.

Added a lifetime for link estimates: if they are too old, they are
...
reset so that a new probing period can produce more up-to-date
estimates. Added a congestion mechanism whereby a neighbor can be
marked as being congested for a period of time, during which the ETX
for the neighbor will be artificially inflated.

Rewrote the initial link estimate logic: link estimates are now
...
computed only over the actual samples, not over the entire
buffer. Also, the initial link estimate is much more conservative now
(16 transmissions) to favor links that have been probed, and which
therefore are likely to have better ETXs.

Moved the definition of the channel check rate used by the radio duty
...
cycling layer. This definition was previously held in net/mac/mac.h,
with the name MAC_CONF_CHANNEL_CHECK_RATE. But since the rate is used
by the radio duty cycling layer, it makes more sense to change its
name to reflect this. Also, the configuration option should be tied to
the netstack configuration instead.
So the new configuration option is called
NETSTACK_CONF_RDC_CHANNEL_CHECK_RATE.

Added support for the Atari to the Contiki download page.
...
The Atari disk image tools don't allow to place contiki.cfg at a fixed location. Therefore the byte offset of the contiki.cfg content isn't constant :-( However using the tool adir with the option -r allows to learn the block number of the contiki.cfg content. So this block number is stored for each Atari disk image in the PHP code (in the array $blk) and translated into the correct byte offset.
