Rewrote the parent selection to favour parents with a low ETX and a good rank. The old parent selection would always favour parents with a lower rank, regardless of their ETX, which in some cases lead to suboptimal parent selections. Also, the old code was buggy in that it would always pick the worst parent (the one with the highest ETX).

Rework of the CSMA layer: instead of using one timer per packet, the module now uses one central timer and a queue of outgoing packets. This helps to keep packets in order, which is extremely useful for TCP transfers, and reduces the amount of congestion since consecutive packets now are spaced in time if there is a collision. Based on the observations and ideas of Simon Duquennoy.

A simple but substantial change: uIP used the htons()/HTONS() macro
...
functions for converting between host and network byte order. These
names are the de facto standard names for this functionality because
of the original BSD TCP/IP implementation. But they cause problems for
uIP/Contiki: some platforms define these names themselves (Mac OS,
most notably), causing compilation problems for Contiki on those
platforms.
This commit changes all htons to uip_htons instead. Same goes for

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.

Don't call sink recv function for zero-size packets, since these most likely are link estimate probes or keepalive packets. Explicitly set eseqno to zero when opening a new connection.

Bugfix: when a node's rtmetric was lower than SIGNIFICANT_RTMETRIC_PARENT_CHANGE, its beacon timers would always be bumped to its lowest value

Several bugfixes to the proactive link estimate maintenance code, which is now enabled by default. Simplified DRAW_TREE code for drawing routing graph in Cooja. Added routing metric penalty to parents that are congested or that drop packets.
