this ensures we never block while writing a MAVLink message to a
serial port, by checking the number of available bytes in the serial
transmit buffer and deferring any message that would cause a blocking
write.
This should prevent the main loop from clagging up due to excessive
telemetry data being sent

moved reading sonar to the 50hz loop so the Mode filter could do it's thing without causing so much latency

Change the way Rate nav works. we now take into account both forward *and lateral* rates. The signs may be backward so be careful! Let me know if the quad shoots off to one side and I'll flip the signs.

RTL no longer yaws towards home
Circle mode for flying a 10m circle around the point where it was engaged. - Not tested at all! Consider Circle mode as alpha.

this makes most of the variables and functions in the main
ArduCopterMega.pde code static, which allows the compiler to optimise
better, and exposes unused variables as compiler warnings

Added Yaw control when descending in Alt hold
