RFM22B: Added timing synchronization on transmit to try to eliminate both sides transmitting at the same time. This now achieves virtually 0 re-transmissions for close range transmission while transmitting both full telemety and PPM at 64k.

USB/COM/RFM22B: Added a standard com callback to test for link availability. This replaces the PIOS_USB_CheckAvailable function with a generic PIOS_COM_Available function. This is now used by the RFM22B com driver to test if a good link is up. This was originally written by James, and Brian merged it into the latest RFM22B branch.

RFM22B/RM: Added rfm22b com device, moved remaining functionality in the radio module to the rfm22 driver, and simplified configuration of the PipX/OPLink. The radio device now presents itself completely as a com device, both in RadioComBridge (OPLink devices) and Telemetry (RM). Also change the PipXStatus and PipXSettings UAVOs to OPLinkStatus/OPLinkSettings.

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).
