data. I don't like this but because of the way the calibration routine works
(sets all gains to 1) this makes the values so far out or range the EKF doesn't
get to run and the mag wasn't previously being updated.

(which is good) but that stops the comms polling. This makes it happen
ocassionally but not too much.

interaction.

data that is all zeros although we shouldn't see this.

little aggressive. Also increased the drift rate of the gyro bias per Sambas'
testing (thanks) although not to the levels required for flying through 40 deg
C transitions.
Made the dump_ekf function handle both numbers of states

default.

than the ekf runs and also be more tolerant of timing jitter

from the AHRS code (which will facilitate code integration with new INS) and
also will help set up a fifo queue for the downsampled data to allow gyro data
output from AHRS faster than EKF output. Also decreased ADC interrupt priority
so the SPI comms don't drop out.

bias correction. This is useful for stabilization to get rid of the gyro bias.
Making it an option is important for calibration.

in practice I need this.

indoor from the name since it's used for both indoor and outdoor mode now.
Increased default value to 0.4 to better reflect the GPS accuracy.

track offset between GPS and baro in outdoor mode.

Changes in ahrs.c for new initialization and to fix issues with outdoor algorithm. The changes in ahrs.c are pretty messy, but committed mostly to get the code to Peabody for more extensive restructuring of ahrs.c.
