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.

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
git-svn-id: https://arducopter.googlecode.com/svn/trunk@2888 f9c3cf11-9bcb-44bc-f272-b75c42450872
Added Yaw control when descending in Alt hold
lowered kP & kD for Alt hold a tad
Adjusted RTL behavior to do speed control up to 4m to home, then go into Loiter

Added camera reversing parameters in AP_Var
Added RTL Throttle Hold set/check
Added dynamic speed control to slow down as you reach waypoints and RTL Home
upped Yaw Dead zone slightly.

Before: -> After
Stabilize P –> Stabilize P (Use NG values, or 8.3 x the older AC2 value)
Stabilize I –> Stabilize I (Stays same value)
Stabilize D –> Rate P (Stays same value)
–> Rate I (new)
Added a new value – an I term for rate. The old stabilization routines did not use this term. Please refer to the config.h file to read more about the new PIDs.
Added framework for using DCM corrected Accelerometer rates. Code is commented out for now.
Added set home at Arming.
Crosstrack is now a full PID loop, rather than just a P gain for more control.
Throttle now slews when switching out of Alt hold or Auto modes for less jarring transitions
Sonar and Baro PIDs are now combined into a throttle PID Yaw control is completely re-written.
Added Octa_Quad support - Max
git-svn-id: https://arducopter.googlecode.com/svn/trunk@2836 f9c3cf11-9bcb-44bc-f272-b75c42450872
Slighted tuned down D term in Loiter PIDs after testing, tuned up P slightly
fixed alt hold bug cause when gaining 3D lock in alt hold.

Reverted to prior Rangefinderlib in case that was causing bad sonar readings.

added D gain to WP_nav to avoid speed oscillations
upped navigation speed to 6m/s from 4.5m/s

Nav loiter D was added (.03) - verify this helps.
