f135105567 Added support for multiple objective functions. 
Extended the objective function API with a callback function that receives link-layer neighbor information.

Throttled DAO transmissions to one per DEFAULT_DAO_LATENCY period.

Added support for an ETX objective function (hysteresis control still lacking though).

Fixed a leak of routes installed by DAOs.

Control that dst_adv_supported is set before sending DAOs.

Improved debugging output.

f6e0b46f38 * Made Chameleon header processing module configurable (CHAMELEON_CONF_MODULE) 
* Removed the unused init function from header processing modules
* Added option CHAMELEON_CONF_WITH_MAC_LINK_ADDRESSES to specify that
  MAC link addresses should be used instead of Chameleon's own encoding
  of sender and receiver. This avoids encoding the link addresses twice
  when the MAC RDC has its own addresses.

e5665fb968 The recent change turning uip_buf from an array to a pointer seems a quite heavyweight way to have the uip_buf alligned to a 32-bit boundary. Contiki is - still - supposed to be portable across a wide range of toolchains - therefore it i.e. intentionally doesn't use C99 features. From that perspective it seems questionable if all toolchains are able to optimize away the overhead imposed by an "unnecessary" indirection to access uip_buf - and uIP consists mostly of accesses to uip_buf. Even if the future is supposed to bring support for multiple uip_bufs which would turn the uip_buf pointer from a mere workaround to an neceesary element on can still presume that there will be targets with resources limited in a way prohibiting the use of several uip_bufs. So at least for those targets will still be a usecase for a "plain", not indirected uip_buf. 
Therefore it seems reasonable to allow to stay with the "plain" uip_buf at compile-time.

7bab9316da Two major changes: 
* Low-power streaming. Experimental support for a low-power mode which
  allows rapid exchange of packets with a 16% duty cycle. Does not
  seem to function correctly yet though.

* Phase locking. When the phase of a neighbor has been detected, the
  sender assumes that the neighbor will keeps it phase and does not
  send more strobes than necessary to hit the receiver's channel
  check - even if the receiver does not acknowledge the reception of
  the strobes when it should have been awake. Instead, the sender
  stops strobing and tries again at a later time.

7165a3866f Significant rework of the Contiki data collection protocol: 
* the new version makes use of MAC-layer feedback so that bad paths
  can be identified quicker and then avoided.

* the new code uses transport layer ACKs that contain feedback from
  the collect protocol: when a packet cannot be forwarded due to lack
  of resources, the ACK contains a flag that indicates that the packet
  could not be forwarded. ACKs also contain the routing metric of the
  sender, which improves agility in face of rapid path changes.

* loop detection and management has been improved: with higher path
  metric agility, the system is more prone to short-lived routing
  loops. Instead of dropping looping packets, the new version adjusts
  the routing metric for the routes that exhibit loops so that the
  risk for future loops is reduced.

* make use of packet attributes to inform the MAC layer of how many
  times packets should be retransmitted.
