b7350118a6 AP_AHRS: enable EKF wind estimate with no airspeed sensor 
EKF can now estimate with IMU and GPS only

4abc2999a6 AP_NavEKF: start with a wind estimate of 3m/s, when no direct measurement 
this will cope better with users with low roll/pitch gains, to ensure
they get enough control on takeoff

d745dc2b6f AP_NavEKF : Increased position gate default to reduce impact of accel errors 
Flight testing with windup turns has shown that the position gate threshold
can be tripped with good GPS data causing position jerks. This increases the
initial GPS glitch rejection threshold to effectively 5m when using the
default POSNE_NOISE value of 0.5m.

188bea6bab AP_NavEKF : Enable calc of wind velocity when not using airspeed sensing 
This patch also cleans up the logic associated with use of the synthetic
sideslip measurement so that it can never be used for a non fly-forward
vehicle type

This patch adds functionality that initialises the wind-speed vector to the
reciprocal of the ground speed vector, and scaled to 6 m/s. On average this gives
a better initial wind velocity estimate on launch by assuming:

a) launch will be into wind
b) wind speed is equal to global average

It also helps prevent a headwind causing initial underestimation of airspeed
causing high autopilot gains and limit cycles on climb-out, until first
turn when the EKF is able to estimate the wind.
