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.

Brian Webb
80509d264e
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).
