RFM22B: Major refactoring of te RFM22B driver to implement a state machine for the driver. The state machine should now be complete, and the driver seems to be working pretty well on both the RM and the pipx.

RFM22B: Start at cleaning up the processing interrupt handling, and starting to make it more of a state machine. Also removed the supervisor, which was causing unnecessary resets. The supervisor functionality is not in the the driver thread.

RFM22b: Block transfers for more large SPI transfers
...
Preallocated buffers with various preambles etc. Used SPI_TransferBlock for
anything over a few bytes instead of burstWrite. Also make more of the
communications wrappered in a large semaphore grab using a new rfm22_write_noclaim()
Still needs work - probably because most of the methods to repeated calls they should
all use the noclaim, or more specifically that function becomes rfm22_write/read.

RFM22b: Begin doing blocks of transfers when possible between semaphore claims
...
The abstraction should probably be improved but ideally we start using
the DMA SPI transfers for PipX and grabbing/releasing the semaphore less
frequently (e.g. not for each 1-2 bytes).

Split out the PipX radio interface from RadioComBridge module to a separate Radio module. Now the RadioComBridge module just routes messages between the com ports and handles sending/receiving the PipX UAVOs.

Added Reed-Solomon error correction to PipXtreme. The code is a slight modification of rsscode ( http://rscode.sourceforge.net ). Packet acking has also been turned on as the default, so each packet is error corrected, and if errors remain, the packet is NACKed, otherwise it is ACKed. Also temporarily turned off UAVTalk parsing. This was causing the CC to be identified as a PipX due to the PipX sending UAVObjects (I believe) from the system module. The system module is going to have to be modified/replaced for the PipX.
