AHRS: removed AP_AHRS_Quaternion
...
this AHRS backend is causing compiler errors with the Arduino build
environment on windows. The quaternion AHRS backend is currently not
being developed/supported anyway. We can resurrect it if someone wants
to start developing it again.

AHRS: avoid a compiler bug in quaternion code
...
Having _wind in the AP_AHRS class causes a register allocation error
when building the Quaternion code with some versions of avr-gcc. Quite
bizarre.

AHRS: added wind estimation code

this allows us to estimate the wind while we have GPS lock, then use
that estimate in the long term dead reckoning

AHRS: normalize the ge vector in drift correction, and use barometer
...
The normalisation ensures the error term scales uniformly with
different accelerations.
The barometer is used for vertical acceleration estimation

DCM: drop the 'drop z' method
...
the 'drop z' method reduced the impact of noise on omegaI, but it also
made us more sensitive to errors in accelerometer calibration and
scaling, as demonstated by the logs from Gabor here:
http://diydrones.com/xn/detail/705844:Comment:834373
Simulation testing shows that the other noise suppression methods
applied in the DCM code, in particular the slope limiting on omegaI
the removal of the weighting and the upcoming use of a _omega_I_sum
buffer have reduced the impact of noise enough that we can now safely
include z in the acceleration calculation.
