Rework of parts of the ContikiMAC code based on input from experimental results. When channel check is triggered because of a false positive, the new version checks the radio several times to make sure that there really is an incoming packet. Otherwise, the radio is switched off. Cleaned up and removed old unused code. Added a few temporary debugging mechanisms and functions.

Improved backoff management: timer is now doubled on every transmission, until the using module calls the neighbor_discovery_start() function again. Don't cancel the transmission even if a lower value arrives (this fixes a problem with multi-hop ETX propagaion).

Reworked the Rime/Chameleon interface so that packets now always hit Rime before Chameleon. Chameleon is now only called by Rime. This makes packet sniffing easier, and allows for sniffing packets after their header has been processed by Chameleon, thereby making per-packet power profiling much easier to implement

A work-in-progress rework of the Contiki MAC and radio layers. The
...
main ideas are:
* Separates the Contiki low-layer network stack into four layers:
network (e.g. sicslowpan / rime), Medium Access Control MAC
(e.g. CSMA), Radio Duty Cycling RDC (e.g. ContikiMAC, X-MAC), and
radio (e.g. cc2420).
* Introduces a new way to configure the network stack. Four #defines
that specify what mechanism/protocol/driver to use at the four
layers: NETSTACK_CONF_NETWORK, NETSTACK_CONF_MAC, NETSTACK_CONF_RDC,
NETSTACK_CONF_RADIO.
* Adds a callback mechanism to inform the MAC and network layers about
the fate of a transmitted packet: if the packet was not possible to
transmit, the cause of the failure is reported, and if the packets
was successfully transmitted, the number of tries before it was
finally transmitted is reported.
* NULL-protocols at both the MAC and RDC layers: nullmac and nullrdc,
which can be used when MAC and RDC functionality is not needed.
* Extends the radio API with three new functions that enable more
efficient radio duty cycling protocols: channel check, pending
packet, and receiving packet.
* New initialization mechanism, which takes advantage of the NETSTACK
#defines.

ntikiMAC: a new radio duty cycling mechanism that uses a combination
...
of link-layer and MAC-layer mechanisms to achieve a very low power
consumption: during idle listening the radio is switched off between
99.2% and 99.6% of the time. One unicast transmission typically adds
between 0.07% and 1.2% additional radio time, depending on packet
size.
ContikiMAC uses the standard IEEE 802.15.4 message format and adds no
additional headers.
ContikiMAC is simple: it uses periodic two-shot channel sampling
during idle listening to keep the radio on-time down. Transmissions
are done with repeated transmissions until a link-layer ACK is
received.
