This is an initial commit of an implementation of the Chameleon
...
architecture for the Rime stack for Contiki. The Chameleon
architecture separates the header processing from the Rime protocol
logic. Instead of having each protocol create its own part of the
packet header, protocols use packet attributes. Before sending a
packet, a special Chameleon header processing module creates a packet
header from the packet attributes. The same Chameleon module parses
incoming packets and creates packet attributes from the header.
The details are in our SenSys 2007 paper:

Architecture for Wireless Sensor Networks. In Proceedings of the Fifth
ACM Conference on Networked Embedded Sensor Systems (SenSys 2007),
Sydney, Australia, November 2007.

Reverted part of recent change. The 32-bit member causes 32-bit alignment on 32-bit machines - at least without specific compiler options. That 32-bit alignment causes padding i.e. the ARP structure breaking the existing code.

Rewrote the process code so that initialization events are posted synchronously instead of asynchronously, so that we don't have to explicitly wait for processes to be initialized. This also reduces the size of the event queue by half on the Tmote Sky platform since the queue was maximized during system bootup. This change also prompted an update of the process invokation code to ensure that a process is not invoked again when processing an event. General cleanup of the code also.

Changed default transmission behaviour to be to send without checking for channel activity first (in anticipation of radio API change that adds a CCA function to the radio API). General code cleanup. Added optional timetable profiling. Added simple_cc2420_get_channel() function, changed simple_cc2420_set_chan_pan to simple_cc2420_set_pan since we now have a dedicated simple_cc2420_set_channel
